† Data in “Typ” column is at 3.0V, 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 5.8 “Using the Data EEPROM” for a more detailed discussion on data EEPROM endurance.
3: Required only if single-supply programming is disabled.
4: The MPLAB ICD 2 does not support variable VPP output. Circuitry to limit the ICD 2 VPP voltage must be placed
between the ICD 2 and target system when programming or debugging with the ICD 2.
