Advance Information DS39919A-page 1 PIC24FXXKAXXX 1.0 DEVICE OVERVIEW This document defines the programming specifications for the PIC24FXXKAXXX family of 16-bit micro- controller devices. This is required only for developing programming support for the PIC24FXXKAXXX family. Users of any one of these devices should use the development tools that are already supporting the device programming. The programming specifications are specific to the following devices: • PIC24F08KA101 • PIC24F16KA101 • PIC24F08KA102 • PIC24F16KA102 • PIC24F04KA200 • PIC24F04KA201 2.0 PROGRAMMING OVERVIEW OF THE PIC24FXXKAXXX FAMILY This section describes the two methods of programming the PIC24FXXKAXXX family of devices: • In-Circuit Serial Programming™ (ICSP™) • Enhanced In-Circuit Serial Programming (Enhanced ICSP) The ICSP programming method is the most direct method for programming 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 device. Section 3.0 “Device Programming – ICSP” describes the ICSP method. The Enhanced ICSP method is a faster method, which takes advantage of the programming executive as illustrated in Figure 2-1. The programming executive provides the necessary functionality to erase, program and verify the device through a command set. The com- mand set allows the programmer to program the PIC24FXXKAXXX devices without having to deal with the low-level programming protocols of the device. Section 4.0 “Device Programming – Enhanced ICSP” describes the ICSP method using the programming executive. FIGURE 2-1: PROGRAMMING SYSTEM OVERVIEW FOR ENHANCED ICSP™ METHOD 2.1 Power Requirements All devices in the PIC24FXXKAXXX family are 3.3V supply designs. The core, the peripherals and the I/O pins operate at 3.3V. The device can operate from 1.8V to 3.6V. 2.2 Entering Programming Mode Overview There are two methods of entering the Programming mode (either ICSP or Enhanced ICSP): • Low-Voltage ICSP Entry When the MCLR/VPP/RA5 pin is used as MCLR by applying VSS on MCLR (low-voltage entry), the device gets reset, and on applying the Program- ming mode entry sequence on the PGCx and PGDx pins, the device enters the Programming mode. • High-Voltage ICSP Entry To enter the Programming mode, if the MCLR function of the MCLR/VPP/RA5 pin needs to be disabled or is already disabled, a voltage VIHH should be applied on VPP (high-voltage entry). This is equivalent to applying VSS on MCLR; the device gets reset. On applying the Programming mode entry sequence on PGCx and PGDx pins, the device enters the Programming mode.
