Note

This depends on the POR detection voltage. For a falling voltage, data in RAM are retained until the voltage

reaches the level that triggers a POR reset but not once it reaches the level at which a POR reset is generated.

Caution

Data in RAM are not retained if the CPU operates outside the specified operating voltage range.

Therefore, place the CPU in STOP mode before the operating voltage drops below the specified range.

Notes 1.

1 erase + 1 write after the erase is regarded as 1 rewrite. The retaining years are until next rewrite after the

rewrite.

When using flash memory programmer and Renesas Electronics self programming library

This characteristic indicates the flash memory characteristic and based on Renesas Electronics reliability test.

Remark

When updating data multiple times, use the flash memory as one for updating data.
