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.

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.

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.

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 I2C™

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.
