PIC24FJ128GA010 FAMILY
1.1.4 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 64-pin to
80-pin to 100-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.
1.2 Other Special Features
• Communications: The PIC24FJ128GA010
family incorporates a range of serial communica-
tion peripherals to handle a range of application
requirements. All devices are equipped with two
independent UARTs with built-in IrDA
encoder/decoders. There are also two indepen-
dent SPI modules, and two independent I²C
modules that support both Master and Slave
modes of operation.
• 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.
1.3 Details on Individual Family
Members
Devices in the PIC24FJ128GA010 family are available
in 64-pin, 80-pin and 100-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:
1. Flash program memory (64 Kbytes for
PIC24FJ64GA devices, 96 Kbytes for
PIC24FJ96GA devices and 128 Kbytes for
PIC24FJ128GA devices).
2. Available I/O pins and ports (53 pins on 6 ports for
64-pin devices, 69 pins on 7 ports for 80-pin
devices and 84 pins on 7 ports for 100-pin
devices). Note also that, since interrupt-on-change
inputs are available on every I/O pin for this family
of devices, the number of CN inputs also differs
between package sizes.
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
PIC24FJ128GA010 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.
