† Data in “Typ” column is at 3.3V, 25°C unless otherwise stated. These parameters are for design guidance
only and are not tested.

These specifications are for programming the on-chip program memory through the use of table write
instructions.
Refer to Section 9.8 “Using the Data EEPROM” for a more detailed discussion on data EEPROM
endurance.
Required only if Single-Supply Programming is disabled.
The MPLAB ICD2 does not support variable VPP output. Circuitry to limit the ICD2 VPP voltage must be
placed between the ICD2 and target system when programming or debugging with the ICD2.
