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.
