13.6 MEMORY CHARACTERISTICS

13.6.1 RAM and Hardware Registers

13.6.2 XFlash Program Memory

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.
