1. Minimum supply voltage without losing data stored in RAM (in halt mode or under reset) or in hardware
Flash program memory/data EEPROM memory
General conditions: T

1. Guaranteed by characterization, not tested in production.
2. The physical granularity of the memory is 4 bytes, so cycling is performed on 4 bytes even when a
