Secured Renesas Microcontroller R5F212A7SDFA Code Extraction needs to crack mcu r5f212a7sdfa security fuse bit by focus ion beam, and dump the embedded binary out from r5f212a7 flash memory;

Endurance to guarantee all electrical characteristics after program and (1 to Min. value can be guaranteed).

If emergency processing is required, a suspend request can be generated independent of this In that case the normal time delay to suspend can be applied to the request. However, we recommend that a suspend request with an interval of less than 650 ms is only used once because, if the suspend state continues, erasure cannot operate and the incidence of erasure error rises.

In a system that executes multiple programming operations, the actual erasure count can be reduced by writing to sequential addresses in turn so that as much of the block as possible is used up before performing an erase operation to extract ic mcu code. For example, when programming groups of 16 bytes, the effective number of rewrites can be minimized by programming up to 128 groups before erasing them all in one;

In addition, averaging the number of erase operations between block A and block B can further reduce the effective number of rewrites. It is also advisable to retain data on the erase count of each block and limit the number of erase operations to a certain number.

If an error occurs during block erase, attempt to execute the clear status register command, then execute the block erase command at least three times until the erase error does not occur to read microcontroller firmware; Customers desiring programming/erasure failure rate information should contact their Renesas technical support.

The data hold time includes time that the power supply is off or the clock is not supplied.
