This family introduces a new line of Microchip devices:
a 16-bit microcontroller family with a broad peripheral
feature set and enhanced computational performance.
The PIC24FJ64GA004 family offers a new migration
option for those high-performance applications which
may be outgrowing their 8-bit platforms, but don’t
require the numerical processing power of a digital
signal processor.

All of the devices in the PIC24FJ64GA004 family
incorporate a range of features that can significantly
reduce power consumption during operation. Key
items include:
• On-the-Fly Clock Switching: The device clock
• Doze Mode Operation: When timing-sensitive
• Instruction-Based Power-Saving Modes: The
1.1.3
All of the devices in the PIC24FJ64GA004 family offer
five different oscillator options, allowing users a range
of choices in developing application hardware. These
include:
• Two Crystal modes using crystals or ceramic
• Two External Clock modes offering the option of a
• A Fast Internal Oscillator (FRC) with a nominal
• A Phase Lock Loop (PLL) frequency multiplier,
• A separate internal RC oscillator (LPRC) with a
The internal oscillator block also provides a stable
reference source for the Fail-Safe Clock Monitor. 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.
