13.6 MEMORY CHARACTERISTICS

Subject to general operating conditions for VDD,fOSC, and TA unless otherwise specified.

13.6.1 RAM and Hardware Registers

13.6.2 FLASH Program Memory

Notes:

1. Minimum VDD supply voltage without losing data stored in RAM (in in HALT mode or under RESET) or in hardware

registers (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.
