12.6 MEMORY CHARACTERISTICS

12.6.1 RAM and Hardware Registers

12.6.2 FLASH 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). Not tested in production.

2. Data based on characterization results, not tested in production.

3. VPP must be applied only during the programming or erasing operation and not permanently for reliability reasons.

4. Data based on simulation results, not tested in production

5. In Write/Erase mode the IDD supply current consumption is the same as in Run mode (section 12.4.1 on page 251)
