PIC24FJ256DA210 FAMILY

1.2 Graphics Controller
With the PIC24FJ256DA210 family of devices,
Microchip introduces the Graphics Controller module,
which acts as an interface between the CPU (mainly
through SFRs) and a display. On-board RAM is pro-
vided for display buffer, scratch areas, images and
fonts. In some cases, the RAM requirements for the
display used exceeds the on-board RAM; external
memory connected through EPMP can be used.
This module provides acceleration for drawing points,
vertical and horizontal lines, rectangles, copying rect-
angles between different locations on screen, drawing
text and decompressing compressed data.
1.3 USB On-The-Go
The USB On-The-Go (USB OTG) module 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 implement-
ing USB Host Negotiation 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.
In addition to USB host functionality,
PIC24FJ256DA210 family devices provide a true
single chip USB solution, including an on-chip
transceiver and voltage regulator, and a voltage boost
generator for sourcing bus power during host
operations.
1.4 Other Special Features
• Peripheral Pin Select: The Peripheral Pin Select
(PPS) feature allows most digital peripherals to be
mapped over a fixed set of digital I/O pins. Users
may independently map the input and/or output of
any one of the many digital peripherals to any one
of the I/O pins.
• Communications: The PIC24FJ256DA210 family
incorporates a range of serial communication
peripherals to handle a range of application
requirements. There are three independent I
2
C™
modules that support both Master and Slave
modes of operation. Devices also have, through
the PPS feature, four independent UARTs with
built-in IrDA
®
encoders/decoders and three SPI
modules.
• Analog Features: All members of the
PIC24FJ256DA210 family include a 10-bit A/D
Converter (ADC) module and a triple comparator
module. The ADC module incorporates program-
mable acquisition time, allowing for a channel to
be selected and a conversion to be initiated
without waiting for a sampling period, and faster
sampling speeds. The comparator module
includes three analog comparators that are
configurable for a wide range of operations.
• CTMU Interface: In addition to their other analog
features, members of the PIC24FJ256DA210
family include the CTMU interface module. This
provides a convenient method for precision time
measurement and pulse generation, and can
serve as an interface for capacitive sensors.
• Enhanced Parallel Master/Parallel Slave Port:
There are general purpose I/O ports, which can
be configured for parallel data communications. In
this mode, the device can be master or slave on
the communication bus. 4-bit, 8-bit and 16-bit data
transfers, with up to 23 external address lines are
supported in Master modes.
• Real-Time Clock and Calendar: (RTCC) 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.
