NOTES:
1.
VCC = 2.7 to 5.5 V at Topr = -40 to 85
°C (J version) / -40 to 125°C (K version), unless otherwise specified.

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 = 10,000), each block can be erased n times.
For example, if 1,024 1-byte writes are performed to different addresses in 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).
3.
MInimum endurance to guarantee all electrical characteristics after program and erase (1 to Min. value can be guaranteed).
4.
Standard of block A and block B when program and erase endurance exceeds 1,000 times. Byte program time to 1,000 times
are the same as that in program ROM.
5.
In a system that executes multiple programming operations, the actual erasure endurance 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. In addition, averaging the erasure endurance between blocks A and B
can further reduce the actual erasure endurance. It is also advisable to retain data on the erasure endurance of each block
and limit the number of erase operations to a certain number.
6.
If error occurs during block erase, attempt to execute the clear status register command, then the block erase command at
least three times until the erase error does not occur.
7.
Customers desiring program/erase failure rate information should contact their Renesas technical support representative.
8.
125
°C for K version.
9.
The data hold time includes time that the power supply is off or the clock is not supplied.
