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 V
isters (only in HALT mode). Guaranteed by construction, not tested in production.
2. Data based on characterization results, tested in production at T
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 T
5. Data based on reliability test results and monitored in production.
