The ATtiny48/88 is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATtiny48/88 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.

The AVR core combines a rich instruction set with 32 general purpose working registers. All the 32 registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two independent registers to be accessed in one single instruction executed in one clock cycle if Reverse engineering pic18f248 MCU.

The resulting architecture is more code efficient while achieving throughputs up to ten times faster than conventional CISC microcontrollers. The ATtiny48/88 provides the following features: 4/8K bytes of In-System Programmable Flash, 64/64 bytes EEPROM, 256/512 bytes SRAM, 24 general purpose I/O lines (28 I/Os in 32-lead TQFP and 32-pad QFN/MLF packages).

32 general purpose working registers, two flexible Timer/Counters with compare modes, internal and external interrupts, a byte-oriented 2-wire serial interface, an SPI serial port, a 6-channel 10-bit ADC (8 channels in 32-lead TQFP and 32-pad QFN/MLF packages), a programmable Watchdog Timer with internal oscillator, and three software selectable power saving modes.

Idle mode stops the CPU while allowing Timer/Counters, 2-wire serial interface, SPI port, and interrupt system to continue functioning. Power-down mode saves the register contents but freezes the oscillator, disabling all other MCU functions until the next interrupt or hardware reset. ADC Noise Reduction mode stops the CPU and all I/O modules except ADC, and helps to minimize switching noise during ADC conversions.

The device is manufactured using Atmel’s high density non-volatile memory technology. The On-MCU ISP Flash allows the program memory to be reprogrammed In-System through an SPI serial interface, by a conventional non-volatile memory programmer, or by an on-MCU boot program running on the AVR core.

The boot program can use any interface to download the application program in the Flash memory. By combining an 8-bit RISC CPU with In-System Self-Programmable Flash on a monolithic MCU, the Atmel ATtiny48/88 is a powerful microcontroller that provides a highly flexible and cost effective solution to many embedded control applications.

The ATtiny48/88 AVR is supported by a full suite of program and system development tools including: C compilers, macro assemblers, program debugger/simulators and evaluation kits. This documentation contains simple code examples that briefly show how to use various parts of the device.

These code examples assume that the part specific header file is included before compilation. 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 documentation for more details.

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. Typical values contained in this datasheet are based on simulations and characterization of other AVR microcontrollers manufactured on the same process technology. Min and Max values will be available after the device is characterized.

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, 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 pre-fetched from the program memory.

This concept enables instructions to be executed in every clock cycle. The program memory is In-System Reprogrammable Flash memory. The fast-access Register File contains 32 x 8-bit general purpose working registers with a single clock cycle access time.

This allows single-cycle Arithmetic Logic Unit (ALU) operation. In a typical ALU operation, two operands are output from the Register File, the operation is executed, and the result is stored back in the Register File – in one clock cycle if Reverse engineering atmega1281 MCU.

Six of the 32 registers can be used as three 16-bit indirect address register pointers for

Data Space addressing – enabling efficient address calculations. One of the these address pointers can also be used as an address pointer for look up tables in Flash program memory. These added function registers are the 16-bit X-, Y-, and Z-register, described later in this section.

The ALU supports arithmetic and logic operations between registers or between a constant and a register. Single register operations can also be executed in the ALU. After an arithmetic operation, the Status Register is updated to reflect information about the result of the operation.

Program flow is provided by conditional and unconditional jump and call instructions, able to directly address the whole address space. Most AVR instructions have a single 16-bit word format. Every program memory address contains a 16- or 32-bit instruction.

Program Flash memory space is divided in two sections, the Boot Program section and the Application Program section. Both sections have dedicated Lock bits for write and read/write protection. The SPM instruction that writes into the Application Flash memory section must reside in the Boot Program section.
