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.

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 20-pin to
28-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.

• 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.
