† 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 7.7 “Using the Data EEPROM” for a more detailed discussion on data EEPROM
endurance.
3: Required only if Single-Supply Programming is disabled.
4: Minimum voltage is 3.2V for PIC18LF devices in the family. Minimum voltage is 4.2V for PIC18F devices in
