1 / 14 page ![]() 2002 Microchip Technology Inc. Preliminary DS39588A-page 1 M PIC16F72 This document includes the programming specifications for the following device: 1.0 PROGRAMMING THE PIC16F72 The PIC16F72 is programmed using a serial method. The Serial mode allows the PIC16F72 to be pro- grammed while in the users’ system, allowing for increased design flexibility. This programming specifi- cation applies to PIC16F72 devices in all packages. 1.1 Hardware Requirements The PIC16F72 requires two programmable power sup- plies, one for VDD (2.0V to 5.5V) and the other for VPP of 12.75V to 13.25V. Both supplies should have a min- imum resolution of 0.25V. 1.2 Programming Mode The Programming mode for the PIC16F72 allows pro- gramming of user program memory, special locations used for ID, and the configuration word.
