16.6 MEMORY CHARACTERISTICS
16.6.1 RAM and Hardware Registers
16.6.2 EEPROM Data Memory
16.6.3 FLASH 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. Data based on characterization results, tested in production at TA=25°C.
3. Up to 16 bytes can be programmed at a time for a 4kBytes FLASH block (then up to 32 bytes at a time for an 8k device)
4. The data retention time increases when the TA decreases.
5. Data based on reliability test results and monitored in production.
