5. Electrical Characteristics

Note:

The value listed in the table is the minimum VCC1 to retain RAM data.

Notes:

Program/erase definition

This value represents the number of erasures per block.

When the number of program/erase cycles is n, each block can be erased n times.

For example, if a 4-word write is performed in 512 different addresses in the 4-Kbyte block A and

then the block is erased, this is counted as a single program/erase operation.

However, the same address cannot be written to more than once per erasure (overwrite disabled).

Data retention includes periods when no supply voltage is applied and no clock is provided.

Contact a Renesas Electronics sales office for data retention times other than the above condition.
