Data Memory STOP Mode Low Supply Voltage Data Retention Characteristics

Note

The value depends on the POR detection voltage. When the voltage drops, the data is retained before a POR reset is

effected, but data is not retained when a POR reset is effected.

2.10

Flash Memory Programming Characteristics

Note 1.

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

Note 2.

When using flash memory programmer and Renesas Electronics self programming library

Note 3.

These are the characteristics of the flash memory and the results obtained from reliability testing by Renesas Electronics

Corporation.
