Break IC Renesas R5F2L388CNFP Firmware

Break IC Renesas R5F2L388CNFP protection, decapsulate the silicon package of Microcontroller R5F2L388CNFP and readout firmware from MCU R5F2L388CNFP data memory and code memory, then make R5F2L388CNFP MCU clone units through this firmware;

Features

The R8C/L35C Group, R8C/L36C Group, R8C/L38C Group, and R8C/L3AC Group of single-chip MCUs when incorporate the R8C CPU core, which implements a powerful instruction set for a high level of efficiency and supports a 1 Mbyte address space, allowing execution of instructions at high speed. In addition, the CPU core integrates a multiplier for high-speed operation processing.

Power consumption is low, and the supported operating modes allow additional power control. These MCUs are designed to maximize EMI/EMS performance.

Integration of many peripheral functions, including multifunction timer and serial interface, helps reduce the number of system components.

These groups have data flash (1 KB × 4 blocks) with the background operation (BGO) function.
