PIC24F04KA201 FAMILY
The internal oscillator block also provides a stable
reference source for the Fail-Safe Clock Monitor
(FSCM). This option constantly monitors the main clock
source against a reference signal provided by the
internal oscillator and enables the controller to switch to
the internal oscillator, allowing for continued low-speed
operation or a safe application shutdown.
1.1.4 EASY MIGRATION
Regardless of the memory size, all the 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 helps in migrating to the next larger
device. This is true when moving between devices with
the same pin count, or even jumping from 14-pin to
20-pin devices. The PIC24F16KA102 family is directly
compatible for migration to larger program and data
memory.
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.
1.2 Other Special Features
• Communications: The PIC24F04KA201 family
incorporates a range of serial communication
peripherals to handle a range of application
requirements. There is an I²C™ module that
supports both the Master and Slave modes of
operation. It also comprises a UART with built-in
IrDA^® encoders/decoders and an SPI module.
• 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, and
faster sampling speed. The 16-deep result buffer
can be used either in Sleep to reduce power, or in
Active mode to improve throughput.
• Charge Time Measurement Unit (CTMU)
Interface: The PIC24F04KA201 family includes
the new CTMU interface module, which can be
used for capacitive touch sensing using
Microchip’s mTouch™ technology, proximity
sensing and also for precision time measurement
and pulse generation.
1.3 Details on Individual Family
Members
Devices in the PIC24F04KA201 family are available in
14-pin and 20-pin packages. The general block
diagram for all devices is displayed in Figure 1-1.
The devices are different from each other in two ways:
1. Number of ADC channels (9 channels on 20-pin
parts, 7 channels on 14-pin parts).
2. Available I/O pins and ports (12 pins on two
ports for 14-pin devices and 18 pins on two ports
for 20-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
PIC24F04KA201 family devices, sorted by function, is
provided in Table 1-2.
Note:
Table 1-1 provides 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 on pages 2 and 3 of the data
sheet. Multiplexed features are sorted by
the priority given to a feature, with the
highest priority peripheral being listed first.
1.4 Differences from PIC24F16KA102
Family
The PIC24F04KA201 family architecture is very similar to
that of the PIC24F16KA102 family. The PIC24F04KA201
family is a subset of the PIC24F16KA102 devices.
The PIC24F16KA102 family has the following
additional features:
• Larger Program Memory
• Larger Data Memory
• CRC Module
• Debugging Capabilities through ICSP™
• Additional I/O on 20-Pin Devices (up to
24 I/O pins)
• Data EEPROM memory
• Boot Segment and General Segments for
Program Code (with available code protection)
• One Additional UART (2 total)
