12.6 MEMORY CHARACTERISTICS
Subject to general operating condition for VDD,fOSC, and TA unless otherwise specified.
12.6.1 RAM and Hardware Registers
12.6.2 EEPROM Data Memory
12.6.3 EPROM Program Memory
Notes:
1. Minimum VDD supply voltage without losing data stored into RAM (in in HALT mode or under RESET) or into hardware
registers (only in HALT mode). Guaranteed by construction, not tested in production.
2. The data retention time increase when the TA decreases.
3. Data based on reliability test results and monitored in production.
4. Data given only as guidelines.
