† Data in “Typ” column is at 3.3V, 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 9.8 “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 MPLAB ICD 2 VPP voltage
must be placed between the MPLAB ICD 2 and the target system when programming or debugging with
the MPLAB ICD 2.
