5. Electrical Characteristics

Notes:

Program/erase definition

This value represents the number of erasures per block.

If the flash memory is programmed/erased n times, each block can be erased n times.

i.e. If 4-word write is performed in 512 different addresses in the block A of 4 Kbyte 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).

The data retention time includes the periods when the supply voltage is not applied and no clock is

provided.

Please contact a Renesas Electronics sales office regarding data retention time other than the

above.
