Reverse ARM STM32F031F4 Microprocessor Source Code from its flash memory, and copy flash firmware to new mcu stm32f031f4 by programmer, the locked bits of microcontroller stm32f031f4 has been disabled by mcu cracking technique;
The MCU is placed under the following conditions:
- VDD = VDDA = 3.3 V
- All I/O pins are in analog input configuration
- The Flash memory access time is adjusted to fHCLK frequency:
- 0 wait state and Prefetch OFF from 0 to 24 MHz
- 1 wait state and Prefetch ON above 24 MHz
- When the peripherals are enabled, fPCLK = fHCLK
- PLL is used for frequencies greater than 8 MHz
AHB prescaler of 2, 4, 8 and 16 is used for the frequencies 4 MHz, 2 MHz, 1 MHz and 500 kHz respectively.
The current consumption of the I/O system has two components: static and dynamic when recover flash firmware from stm32f031e6 arm microcontroller.
All the I/Os used as inputs with pull-up generate current consumption when the pin is externally held low. The value of this current consumption can be simply computed by using the pull-up/pull-down resistors values given in Table 46: I/O static characteristics.
обратный исходный код микропроцессора ARM STM32F031F4 из его флэш-памяти и копирование прошивки флэш-памяти на новый микроконтроллер STM32F031F4 с помощью программиста, заблокированные биты микроконтроллера STM32F031F4 были отключены методом взлома микроконтроллера;
For the output pins, any external pull-down or external load must also be considered to estimate the current consumption. Additional I/O current consumption is due to I/Os configured as inputs if an intermediate voltage level is externally applied by breaking arm microprocessor stm32f030cc flash memory.
This current consumption is caused by the input Schmitt trigger circuits used to discriminate the input value. Unless this specific configuration is required by the application, this supply current consumption can be avoided by configuring these I/Os in analog mode. This is notably the case of ADC input pins which should be configured as analog inputs.
