PIC24FJ128GC010 FAMILY
1.2 Advanced Analog Features
The centerpiece of the PIC24FJ128GC010 family is the
advanced analog block. This feature set provides appli-
cation developers with all the tools they need for single
chip applications that demand high analog performance.
Included in the advanced analog block are:
• A new 12-bit, pipelined A/D Converter (A/D)
module. A major departure from previous PIC24F
A/D Converters, this module offers up to
50 single-ended input channels (or up to 25 differ-
ential channel pairs) and conversion rates of up to
ten million samples per second. It also provides a
wider range of new features that allow the con-
verter to assess and make decisions on incoming
data without CPU intervention.
• A dual differential channel, Sigma-Delta A/D Con-
verter, for applications requiring high-precision
conversions (up to 16-bit resolution). The
Sigma-Delta Converter also offers programmable
gain on each channel pair, and user-configurable
data rate, between 976 samples per second and
62.5 ksps.
• Two independent, 10-bit Digital-to-Analog
Converters (DACs), each capable of conversion
rates up to one million samples per second.
• A comparator module with three analog compara-
tors that are configurable for a wide range of
operations. The comparators also have their own
independent, configurable voltage reference.
• A dual operational amplifier module with multiple
input options, selectable power modes, and
rail-to-rail operation on the inputs and outputs.
Each of the op amps can also be configured to
function as a comparator, complete with interrupt
generation.
• A dedicated, integrated band gap voltage refer-
ence for all analog modules, providing a range of
on-chip reference voltages and two buffered
reference outputs.
• Flexible multiplexing options for the entire analog
block, allowing for the convenient sharing of
signals between the analog modules.
1.3 DMA Controller
PIC24FJ128GC010 family devices also add a Direct
Memory Access (DMA) controller to the existing
PIC24F architecture. The DMA acts in concert with the
CPU, allowing data to move between data memory and
peripherals without the intervention of the CPU,
increasing data throughput, and decreasing execution
time overhead. Six independently programmable chan-
nels make it possible to service multiple peripherals at
virtually the same time, with each channel peripheral
performing a different operation. Many types of data
transfer operations are supported.
1.4 USB On-The-Go (OTG)
USB On-The-Go provides on-chip functionality as a
target device compatible with the USB 2.0 standard, as
well as limited stand-alone functionality as a USB
embedded host. By implementing USB Host Negotia-
tion Protocol (HNP), the module can also dynamically
switch between device and host operation, allowing
for a much wider range of versatile USB-enabled
applications on a microcontroller platform.
PIC24FJ128GC010 family devices also incorporate an
integrated USB transceiver and precision oscillator,
minimizing the required complexity of implementing a
complete USB device, embedded host, dual role or
On-The-Go application.
1.5 LCD Controller
With the PIC24FJ128GC010 family of devices,
Microchip introduces its versatile Liquid Crystal Display
(LCD) controller and driver to the PIC24F family. The
on-chip LCD driver includes many features that make
the integration of displays in low-power applications
easier. These include an integrated voltage regulator
with charge pump and an integrated internal resistor
ladder that allows contrast control in software, and
display operation above device VDD.
