DS39768D-page 1 PIC24FJXXXGA0XX 1.0 DEVICE OVERVIEW This document defines the programming specification for the PIC24FJXXXGA0XX family of 16-bit micro- controller devices. This programming specification is required only for those developing programming support for the PIC24FJXXXGA0XX family. Customers using only one of these devices should use development tools that already provide support for device programming. This specification includes programming specifications for the following devices: 2.0 PROGRAMMING OVERVIEW OF THE PIC24FJXXXGA0XX FAMILY There are two methods of programming the PIC24FJXXXGA0XX family of devices discussed in this programming specification. They are: • In-Circuit Serial Programming™ (ICSP™) • Enhanced In-Circuit Serial Programming (Enhanced ICSP) The ICSP programming method is the most direct method to program the device; however, it is also the slower of the two methods. It provides native, low-level programming capability to erase, program and verify the chip. The Enhanced In-Circuit Serial Programming (Enhanced ICSP) protocol uses a faster method that takes advantage of the programming executive, as illustrated in Figure 2-1. The programming executive provides all the necessary functionality to erase, pro- gram and verify the chip through a small command set. The command set allows the programmer to program the PIC24FJXXXGA0XX devices without having to deal with the low-level programming protocols of the chip. FIGURE 2-1: PROGRAMMING SYSTEM OVERVIEW FOR ENHANCED ICSP™ This specification is divided into major sections that describe the programming methods independently. Section 4.0 “Device Programming – Enhanced ICSP” describes the Run-Time Self-Programming (RTSP) method. Section 3.0 “Device Programming – ICSP” describes the In-Circuit Serial Programming method. 2.1 Power Requirements All devices in the PIC24FJXXXGA0XX family are dual voltage supply designs: one supply for the core and peripherals and another for the I/O pins. A regulator is provided on-chip to alleviate the need for two external voltage supplies. All of the PIC24FJXXXGA0XX devices power their core digital logic at a nominal 2.5V. To simplify system design, all devices in the PIC24FJXXXGA0XX family incorporate an on-chip regulator that allows the device to run its core logic from VDD. • PIC24FJ16GA002 • PIC24FJ96GA006 • PIC24FJ16GA004 • PIC24FJ96GA008 • PIC24FJ32GA002 • PIC24FJ96GA010 • PIC24FJ32GA004 • PIC24FJ128GA006 • PIC24FJ48GA002 • PIC24FJ128GA008 • PIC24FJ48GA004 • PIC24FJ128GA010 • PIC24FJ64GA002 • PIC24FJ64GA004 • PIC24FJ64GA006 • PIC24FJ64GA008 • PIC24FJ64GA010 PIC24FJXXXGA0XX Programmer Programming Executive On-Chip Memory PIC24FJXXXGA0XX Flash Programming Specification |
