5. Electrical Characteristics
Notes:
1.
Program/erase definition
This value represents the number of erasure per block.
If the flash memory is programmed/erased n times, each block can be erased n times.
i.e. If a word write is performed in different 16 addresses in a block and then the block is erased, it
is considered the programming/erasure is performed just once. However a write in the same
address more than once for one erasure is disabled. (overwrite disabled).
2.
The data retention time includes the periods when the supply voltage is not applied and no clock is
provided.
3.
This data retention includes 3000 hours in Ta = 125°C and 7000 hours in Ta = 85°C.
4.
Please contact a Renesas sales office regarding data retention time other than the above.
