Make sure to turn on the A/D converter power supply (AVCC, AVRH, AVRL) and analog inputs (AN0 to AN23) after turning-on the digital power supply (VCC).

Turn-off the digital power after turning off the A/D converter supply and analog inputs. In this case, make sure that the voltage does not exceed AVRH or AVCC (turning on/off the analog and digital power supplies simulta- neously is acceptable).

The X0, X1 pins and X0A, X1A pins may be possible causes of abnormal operation. Make sure to provide bypass capacitors via the shortest distance from X0, X1 pins and X0A, X1A pins, crystal oscillator (or ceramic oscillator) and ground lines, and make sure, to the utmost effort, that the oscillation circuit lines do not cross the lines of other circuits. It is highly recommended to provide a printed circuit board art work surrounding X0, X1 pins and X0A, X1A pins with a ground area for stabilizing the operation.

For each of the mass-production products, request an oscillator evaluation from the manufacturer of the oscillator you are using. The MB90340E Series does not support internal pull-up/down resistors (except for the pull-up resistors built into ports 0 to 3). Use external components where needed. If you do not connect pins X0A and X1A to an oscillator, use pull-down handling on the X0A pin, and leave the X1A pin open.

If PLL clock mode is selected, the microcontroller attempt to be working with the self-oscillating circuit even when there is no external oscillator or the external clock input is stopped. Performance of this operation, however, cannot be guaranteed. To prevent the internal regulator circuit from malfunctioning, set the voltage rise time during power-on to 50 ms or more (0.2 V to 2.7 V)

CMOS IC chips may suffer latch-up under the following conditions:

A voltage higher than VCC or lower than VSS is applied to an input or output

A voltage higher than the rated voltage is applied between VCC and VSS

The AVCC power supply is applied before the VCC

Latch-up may increase the power supply current drastically, causing thermal damage to the device.

For the same reason, also be careful not to let the analog power-supply voltage (AVCC, AVRH) exceed the digital power-supply voltage.

Leaving unused input pins open may result in misbehavior or latch-up and possible permanent damage to the device. Therefore they must be pulled up or pulled down through resistors. In this case those resistors should be more than 2 kL .

Unused bidirectional pins should be set to the output state and can be left open, or the input state with the above described connection.

If there are multiple VCC and VSS pins, that are designed to be set to the same potential are connected the inside of the device to prevent malfunctions such as latch-up.

To reduce unnecessary radiation, prevent malfunctioning of the strobe signal due to the rise of ground level, and observe the standard for total output current, be sure to connect the VCC and VSS pins to the power supply and ground externally. Connect VCC and VSS pins to the device from the current supply source at a low impedance.

Output transition is not programmable.

CAN module is enhanced: ST10F273 implements two C-CAN modules, so the programming model is slightly different. Besides, the possibility to map in parallel the two CAN modules is added (on P4.5/P4.6).

On-chip main oscillator input frequency range has been reshaped, reducing it from 1 to 25 MHz down to 4 to 12 MHz. This is a low power oscillator amplifier, that allows a power consumption reduction when Real Time Clock is running in Power down mode, using as reference the on-chip main oscillator clock. When this on-chip amplifier is used as reference for Real Time Clock module, the Power-down consumption is dominated by the consumption of the oscillator amplifier itself.

A second on-chip oscillator amplifier circuit (32 kHz) is implemented for low power modes: it can be used to provide the reference to the Real Time Clock counter (either in Power down or Stand-by mode). Pin XTAL3 and XTAL4 replace a couple of VDD/VSS pins of ST10F272M-4QR3.

8-bit bidirectional I/O port, bit-wise programmable for input or output via direction bit. Programming an I/O pin as input forces the corresponding output driver to high impedance state. Port 6 outputs can be configured as push-pull or open drain drivers. The input threshold of Port 6 is selectable (TTL or CMOS). The following Port 6 pins have alternate functions:

External access enable pin.

A low level applied to this pin during and after Reset forces the ST10F273 to start the program from the external memory space. A high level forces ST10F273 to start in the internal memory space. This pin is also used (when Stand-by mode is entered, that is ST10F273 under reset and main VDD turned off) to bias the 32 kHz oscillator amplifier circuit and to provide a reference voltage for the low-power embedded voltage regulator which generates the internal 1.8V supply for the RTC module (when not disabled) and to retain data inside the Stand-by portion of the XRAM (16Kbyte).

It can range from 4.5 to 5.5V (6V for a reduced amount of time during the device life, 4.0V when RTC and 32 kHz on-chip oscillator amplifier are turned off). In running mode, this pin can be tied low during reset without affecting 32 kHz oscillator, RTC and XRAM activities, since the presence of a stable VDD guarantees the proper biasing of all those modules.

CLKOUT function can output either the CPU clock (like in ST10F272M-4T3) or a software programmable prescaled value of the CPU clock. On-chip RAM memory and FLASH size have been increased. PLL multiplication factors have been adapted to new frequency range. A/D Converter is not fully compatible versus ST10F272M-4T3 (timing and programming model). Formula for the conversion time is still valid, while the sampling phase programming model is different.

Besides, additional 8 channels are available on P1L pins as alternate function: The accuracy reachable with these extra channels is reduced with respect to the standard Port5 channels. External Memory bus is affected by limitations on maximum speed and maximum capacitance load: ST10F272m is not able to address an external memory at 64 MHz with 0 wait states in the process of cloning flash memory of locked mcu st10f272m.

The independent watchdog is based on a 12-bit downcounter and 8-bit prescaler. It is clocked from an independent 40 kHz internal RC and as it operates independently of the main clock, it can operate in Stop and Standby modes. It can be used either as a watchdog to reset the device when a problem occurs after replicating stm32f105r8 mcu chip embedded flash program, or as a free-running timer for application timeout management. It is hardware- or software-configurable through the option bytes. The counter can be frozen in debug mode.

The window watchdog is based on a 7-bit downcounter that can be set as free-running. It can be used as a watchdog to reset the device when a problem occurs. It is clocked from the main clock. It has an early warning interrupt capability and the counter can be frozen in debug mode.

This timer is dedicated for OS, but can be used also as a standard downcounter. It features:

• A 24-bit downcounter
• Autoreload capability
• Maskable system interrupt generation when the counter reaches 0
• Programmable clock source

Up to two I²C bus interfaces can operate in multimaster and slave modes. They can support standard and fast modes. They support dual slave addressing (7-bit only) and both 7/10-bit addressing in master mode to decrypt mcu chip stm32f105vc secured memory binary program. A hardware CRC generation/verification is embedded. They can be served by DMA and they support SM Bus 2.0/PM Bus.

The advanced-control timer (TIM1) can be seen as a three-phase PWM multiplexed on 6 channels. It has complementary PWM outputs with programmable inserted dead-times. It can also be seen as a complete general-purpose timer. The 4 independent channels can be used for

• Input capture
• Output compare
• PWM generation (edge- or center-aligned modes)
• One-pulse mode output

If configured as a general-purpose 16-bit timer, it has the same features as the TIMx timer. If configured as the 16-bit PWM generator, it has full modulation capability (0-100%).

In debug mode, the advanced-control timer counter can be frozen and the PWM outputs disabled to turn off any power switch driven by these outputs.

Many features are shared with those of the general-purpose TIM timers which have the same architecture. The advanced-control timer can therefore work together with the TIM timers via the Timer Link feature for synchronization or event chaining to recover stm32f103c6 locked mcu flash full content.

There are up to three synchronizable general-purpose timers embedded in the STM32F103xx performance line devices. These timers are based on a 16-bit auto-reload up/down counter, a 16-bit prescaler and feature four independent channels each for input capture/output compare, PWM or one-pulse mode output. This gives up to 12 input captures/output compares/PWMs on the largest packages.

The general-purpose timers can work together with the advanced-control timer via the Timer Link feature for synchronization or event chaining. Their counter can be frozen in debug mode. Any of the general-purpose timers can be used to generate PWM outputs. They all have independent DMA request generation when recovering arm microprocessor stm32f103cb flash program.

These timers are capable of handling quadrature (incremental) encoder signals and the digital outputs from one to three Hall-effect sensors.

The device has an integrated power-on reset (POR) / power-down reset (PDR) circuitry. It is always active, and ensures proper operation starting from/down to 2 V to pull out stm32f103t8 microcontroller flash data. The device remains in reset mode when VDD is below a specified threshold, VPOR/PDR, without the need for an external reset circuit.

The device features an embedded programmable voltage detector (PVD) that monitors the VDD/VDDA power supply and compares it to the VPVD threshold. An interrupt can be generated when VDD/VDDA drops below the VPVD threshold and/or when VDD/VDDA is higher than the VPVD threshold. The interrupt service routine can then generate a warning message and/or put the MCU into a safe state. The PVD is enabled by software.

The regulator has three operation modes: main (MR), low-power (LPR) and power down.

• MR is used in the nominal regulation mode (Run)
• LPR is used in the Stop mode
• Power down is used in Standby mode: the regulator output is in high impedance: the kernel circuitry is powered down, inducing zero consumption (but the contents of the registers and SRAM are lost)

This regulator is always enabled after reset. It is disabled in Standby mode, providing high impedance output. The STM32F103xx performance line supports three low-power modes to achieve the best compromise between low-power consumption, short startup time and available wakeup sources:

• Sleep mode

In Sleep mode, only the CPU is stopped. All peripherals continue to operate and can wake up the CPU when an interrupt/event occurs.

• Stop mode

The Stop mode achieves the lowest power consumption while retaining the content of SRAM and registers. All clocks in the 1.8 V domain are stopped by cracking stm32f103vet7 arm ic mcu flash memory, the PLL, the HSI RC and the HSE crystal oscillators are disabled. The voltage regulator can also be put either in normal or in low-power mode.

System clock selection is performed on startup, however the internal RC 8 MHz oscillator is selected as default CPU clock on reset. An external 4-16 MHz clock can be selected, in which case it is monitored for failure. If failure is detected, the system automatically switches back to the internal RC oscillator when restoring stm32f103c4 arm microcontroller flash binary file. A software interrupt is generated if enabled. Similarly, full interrupt management of the PLL clock entry is available when necessary (for example on failure of an indirectly used external crystal, resonator or oscillator).

Several prescalers allow the configuration of the AHB frequency, the high-speed APB (APB2) and the low-speed APB (APB1) domains. The maximum frequency of the AHB and the high-speed APB domains is 72 MHz. The maximum allowed frequency of the low-speed APB domain is 36 MHz. See Figure 2 for details on the clock tree.

At startup, boot pins are used to select one of three boot options:

• Boot from user Flash
• Boot from System memory
• Boot from embedded SRAM

The boot loader is located in System memory. It is used to reprogram the Flash memory by using USART1. For further details refer to AN2606, available on www.st.com.

• VDD = 2.0 to 3.6 V: external power supply for I/Os and the internal regulator. Provided externally through VDD
• VSSA, VDDA = 2.0 to 3.6 V: external analog power supplies for ADC, reset blocks, RCs and PLL (minimum voltage to be applied to VDDA is 2.4 V when the ADC is used) by restoring stm32f103c8 microcontroller flash program code. VDDA and VSSA must be connected to VDD and VSS,
• VBAT = 8 to 3.6 V: power supply for RTC, external clock 32 kHz oscillator and backup registers (through power switch) when VDD is not present.

For more details on how to connect power pins, refer to Figure 14: Power supply scheme.

Input to the inverting Oscillator amplifier and input to the internal clock operating circuit. Output from the inverting Oscillator amplifier if enabled by Fuse. Also serves as a generic I/O. This documentation contains simple code examples that briefly show how to use various parts of the device. Be aware that not all C compiler vendors include bit definitions in the header files and interrupt handling in C is compiler dependent. Please confirm with the C compiler documen- tation for more details.

These code examples assume that the part specific header file is included before compilation. For I/O registers located in extended I/O map, “IN”, “OUT”, “SBIS”, “SBIC”, “CBI”, and “SBI” instructions must be replaced with instructions that allow access to extended I/O. Typically “LDS” and “STS” combined with “SBRS”, “SBRC”, “SBR”, and “CBR”. Reliability Qualification results show that the projected data retention failure rate is much less than 1 PPM over 20 years at 85°C or 100 years at 25°C.

This section discusses the AVR core architecture in general. The main function of the CPU core is to ensure correct program execution. The CPU must therefore be able to access memories when reversing atmega16u2 microcontroller protection, perform calculations, control peripherals, and handle interrupts.

In order to maximize performance and parallelism, the AVR uses a Harvard architecture – with separate memories and buses for program and data. Instructions in the program memory are executed with a single level pipelining. While one instruction is being executed, the next instruction is prefetched from the program memory after recovering atmega8u2 encrypted microprocessor flash memory. This concept enables instructions to be executed in every clock cycle. The program memory is In-System Reprogrammable Flash memory.

The ATmega8U2/16U2/32U2 are supported with a full suite of program and system develop- ment tools including: C compilers, macro assemblers, program debugger/simulators, in-circuit emulators, and evaluation kits.

AVCC is the supply voltage pin (input) for all analog features (Analog Comparator, PLL). It should be externally connected to VCC through a low-pass filter.

Port B is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The Port B output buffers have symmetrical drive characteristics with both high sink and source capability. As inputs, Port B pins that are externally pulled low will source current if the pull-up resistors are activated. The Port B pins are tri-stated when a reset condition becomes active, even if the clock is not running.

Port B also serves the functions of various special features of the ATmega8U2/16U2/32U2 as listed on page 74. Port D serves as analog inputs to the analog comparator.

Port D also serves as an 8-bit bi-directional I/O port, if the analog comparator is not used (con- cerns PD2/PD1 pins). Port pins can provide internal pull-up resistors (selected for each bit). The Port D output buffers have symmetrical drive characteristics with both high sink and source capability. As inputs, Port D pins that are externally pulled low will source current if the pull-up resistors are activated. The Port D pins are tri-stated when a reset condition becomes active, even if the clock is not running.

Reset input. A low level on this pin for longer than the minimum pulse length will generate a reset, even if the clock is not running. The minimum pulse length is given in “System Control and Reset” on page 47. Shorter pulses are not guaranteed to generate a reset. This pin alternatively serves as debugWire channel or as generic I/O. The configuration depends on the fuses RST- DISBL and DWEN.
