Notes:

1. Minimum VDD supply voltage without losing data stored in RAM (in HALT mode or under RESET) or in hardware reg-

isters (only in HALT mode). Guaranteed by construction, not tested in production.

2. Up to 32 bytes can be programmed at a time.

3. The data retention time increases when the TA decreases.

4. Data based on reliability test results and monitored in production.

5. Data based on characterization results, not tested in production.

6. Guaranteed by Design. Not tested in production.

7. Design target value pending full product characterization.
