Break R5F21292SDSP Locked MCU Flash Memory and clone microcontroller r5f21292 heximal file to new units which will provide the same functions as original ones;
VCC = 2.7 to 5.5 V at Topr = -20 to 85°C (N version) / -40 to 85°C (D version), unless otherwise specified.
The programming and erasure endurance is defined on a per-block basis.
If the programming and erasure endurance is n (n = 100 or 10,000), each block can be erased n times. For example, if 1,024 1-byte writes are performed to block A, a 1 Kbyte block, and then the block is erased, the programming/erasure endurance still stands at one.
However, the same address must not be programmed more than once per erase operation (overwriting prohibited).
Endurance to guarantee all electrical characteristics after program and erase. (1 to Min. value can be guaranteed).
Standard of block A and block B when program and erase endurance exceeds 1,000 times. Byte program time to 1,000 times is the same as that in program ROM.
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. 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 operation.
