† Data in “Typ” column is at 5.0V, 25°C unless otherwise stated. These parameters are for design guidance

only and are not tested.

Note 1: These specifications are for programming the on-chip program memory through the use of table write

instructions.

2: Refer to Section 7.8 “Using the Data EEPROM” for a more detailed discussion on data EEPROM

endurance.

3: Required only if single-supply programming is disabled.
