Notes 1.

1 erase + 1 write after the erase is regarded as 1 rewrite.

The retaining years are until next rewrite after the rewrite.

2. When using flash memory programmer and Renesas Electronics self programming library.

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

Electronics Corporation.

4. The specified data retention time is given under the condition that the average temperature (TA) is 85°C or

below.

Caution Different voltage between EVDD and VDD is allowed only when LCDM register is initial value.
