For each physical address
† 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:
2:
3:
These specifications are for programming the on-chip program memory through the use of table write
instructions.
Refer to Section 8.8 “Using the Data EEPROM” for a more detailed discussion on data EEPROM
endurance.
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.
