Data in “Typ” column is at 3.0V, 25°C unless otherwise stated. These parameters are for design guidance
only and are not tested.
Self-write and Block Erase.
Refer to Section 11.2 “Using the Data EEPROM” for a more detailed discussion on data EEPROM
endurance.
Required only if single-supply programming is disabled.
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.
