Dump Protective STM32F038K6 Microprocessor Firmware from its locked flash memory, security locked bit will be broken by focus ion beam technique which is one of the most commonly used method for breaking microcontroller stm32f038k6 fuse bit, and then readout embedded heximal file from stm32f038k6 mcu flash memory;
The I2C interface meets the timings requirements of the I2C-bus specification and user manual rev. 03 for:
The I2C timings requirements are guaranteed by design when the I2Cx peripheral is properly configured (refer to Reference manual).
The SDA and SCL I/O requirements are met with the following restrictions: the SDA and SCL I/O pins are not “true” open-drain by replicating stm32f031c6 microcontroller flash program. When configured as open-drain, the PMOS connected between the I/O pin and VDDIOx is disabled, but is still present. Only FTf I/O pins support Fm+ low level output current maximum requirement.
Refer to Section 6.3.13: I/O port characteristics for the I2C I/Os characteristics. All I2C SDA and SCL I/Os embed an analog filter. Refer to the table below for the analog filter characteristics:
