EASY MIGRATION

Regardless of the memory size, all devices share the

same rich set of peripherals, allowing for a smooth

migration path as applications grow and evolve.

The consistent pinout scheme used throughout the

entire family also aids in migrating to the next larger

device. This is true when moving between devices with

the same pin count, or even jumping from 28-pin to

44-pin devices.

The PIC24F family is pin-compatible with devices in the

dsPIC33 family, and shares some compatibility with the

pinout schema for PIC18 and dsPIC30. This extends

the ability of applications to grow from the relatively

simple, to the powerful and complex, yet still selecting

a Microchip device.

Other Special Features

• Communications: The PIC24FJ64GA004 family

incorporates a range of serial communication

peripherals to handle a range of application

requirements. There are two independent I2C

modules that support both Master and Slave

modes of operation. Devices also have, through

the peripheral pin select feature, two independent

UARTs with built-in IrDA encoder/decoders and

two SPI modules.

• Peripheral Pin Select: The peripheral pin select

feature allows most digital peripherals to be

mapped over a fixed set of digital I/O pins. Users

may independently map the input and/or output of

any one of the many digital peripherals to any one

of the I/O pins.

• Parallel Master/Enhanced Parallel Slave Port:

One of the general purpose I/O ports can be

reconfigured for enhanced parallel data communi-

cations. In this mode, the port can be configured

for both master and slave operations, and

supports 8-bit and 16-bit data transfers with up to

16 external address lines in Master modes.

• Real-Time Clock/Calendar: This module

implements a full-featured clock and calendar with

alarm functions in hardware, freeing up timer

resources and program memory space for use of

the core application.

• 10-Bit A/D Converter: This module incorporates

programmable acquisition time, allowing for a

channel to be selected and a conversion to be

initiated without waiting for a sampling period, as

well as faster sampling speeds.

Details on Individual Family

Members

Devices in the PIC24FJ64GA004 family are available

in 28-pin and 44-pin packages. The general block

diagram for all devices is shown in Figure 1-1.

The devices are differentiated from each other in two

ways:

Flash program memory (64 Kbytes for

PIC24FJ64GA

devices,

Kbytes

for

PIC24FJ48GA

devices,

Kbytes

for

PIC24FJ32GA devices and 16 Kbytes for

PIC24FJ16GA devices).

Internal SRAM memory (4k for PIC24FJ16GA

devices, 8k for all other devices in the family).

Available I/O pins and ports (21 pins on 2 ports

for 28-pin devices and 35 pins on 3 ports for

44-pin devices).

All other features for devices in this family are identical.

These are summarized in Table 1-1.

A list of the pin features available on the

PIC24FJ64GA004 family devices, sorted by function, is

shown in Table 1-2. Note that this table shows the pin

location of individual peripheral features and not how

they are multiplexed on the same pin. This information

is provided in the pinout diagrams in the beginning of

the data sheet. Multiplexed features are sorted by the

priority given to a feature, with the highest priority

peripheral being listed first.
