† 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: Self-write and Block Erase.
2: Refer to Section 11.2 “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 V
PP output. Circuitry to limit the MPLAB ICD 2 VPP voltage must
be placed between the MPLAB ICD 2 and target system when programming or debugging with the MPLAB
ICD 2.
