Notes: 1. Definition of programming/erasure endurance
The programming and erasure endurance is defined on a per-block basis.
If the programming and erasure endurance is n (n = 1000, 10000), each block can be
erased n times.
For example, if 1024 4-byte writes are performed to different addresses in data flash A,
a 4-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).
2. Endurance to guarantee all electrical characteristics after program and erase (1 to Min.
value can be guaranteed).
3. 40°C for D version.
