Break R5F21258SNFP MCU Flash Memory Locking and clone renesas r5f21258sn flash memory content from original chip, extract microprocessor embedded firmware from its flash memory.

R5F21258SNFP has an On-chip Brown-out Detection (BOD) circuit for monitoring the VCC level during operation by comparing it to a fixed trigger level. The trigger level for the BOD can be selected by the fuse BODLEVEL to be

2.7V (BODLEVEL unprogrammed), or 4.0V (BODLEVEL programmed). The trigger level has a hysteresis to ensure spike free Brown-out Detection when copy r5f212aasd locked flash memory data. The hysteresis on the detection level should be interpreted as VBOT+ = VBOT

+ VHYST/2 and VBOT- = VBOT – VHYST/2.

The BOD circuit can be enabled/disabled by the fuse BODEN. When the BOD is enabled (BODEN programmed), and VCC decreases to a value below the trigger level (VBOT- in Figure 11-5), the Brown-out Reset is immediately activated after reverse engineering r5f21226df microprocessor binary code. When VCC increases above the trigger level (VBOT+ in Figure 11-5), the delay counter starts the MCU after the time-out period tTOUT has expired. The BOD circuit will only detect a drop in VCC if the voltage stays below the trigger level for longer than tBOD given in Table 26-3 on page 235.
