ST Microcomputer ST72F340K2 Flash Program Memory Unlocking needs to disable the fuse bit of tamper resistance system and readout embedded firmware from Microcontroller, pull extracted heximal to new st72f340k2 microprocessor flash memory;

To perform ICP the microcontroller must be switched to ICC (In-Circuit Communication) mode by an external controller or programming tool.

Depending on the ICP code downloaded in RAM, Flash memory programming can be fully customized (number of bytes to program, program locations, or selection serial communication interface for downloading) when copy embedded binary firmware to new microcontroller st72f325s6.

When using an STMicroelectronics or third-party programming tool that supports ICP and the specific microcontroller device, the user needs only to implement the ICP hardware interface on the application board (see below Figure). For more details on the pin locations, refer to the device pinout description.

This mode uses a BootLoader program previously stored in Sector 0 by the user (in ICP mode or by plugging the device in a programming tool). This mode is fully controlled by user software in the process of cloning st72f325k4 secured microcontroller flash memory content. This allows it to be adapted to the user application, (us- er-defined strategy for entering programming mode, choice of communications protocol used to fetch the data to be stored, etc.).
