Note 1. The reprogram/erase cycle is the number of erasures for each block. When the reprogram/erase cycle is n times (n = 1,000),

erasing can be performed n times for each block. For instance, when 4-byte programming is performed 512 times for different

addresses in 2-KB blocks, and then the entire block is erased, the reprogram/erase cycle is counted as one. However, programming

the same address for several times as one erasure is not enabled (overwriting is prohibited).

Note 2. Characteristic when using the flash memory programmer and the self-programming library provided by Renesas Electronics.

Note 3. This result is target spec, may changed after reliability testing.
