This document is about the programming specifications for PIC16F/LF720 and PIC16F/LF721 devices. These devices can be programmed using In-Circuit Serial Programming™ (ICSP™). Except for memory size and the voltage regulator, all other aspects of the PIC16F/LF720 and PIC16F/LF721 devices are identical.
The document defines the flash memory programming specifications for the PIC16F/LF720 and PIC16F/LF721 devices. Programming is performed via In‑Circuit Serial Programming (ICSP) using five dedicated pins.
It details pin assignments, memory map layouts, configuration and calibration words, and code‑protection features, and provides hardware requirements and contact information for Microchip support.
