PIC32 Low Cost Controllerless Graphics:
32-bit Performance, Flexibility, Integration
Microchip’s PIC32 line of 32-bit microcontrollers offers
80MIPS and high performance DMA to render graphics
directly to displays. This enables PIC32 devices to drive a
display without an external graphics controller.
■ Uses <5 MIPS and DMA to render graphics
• Direct interface to STN, TFT displays
■ Integrated 128 KB frame buffer
• Supports QVGA 8 bpp with internal frame buffer
• Supports WQVGA 16 bpp with external frame buffer
using PMP (Parallel Master Port)
■ Works with any PIC32 80 MIPS 32-bit microcontroller
With devices offering up to 512 KB Flash and 128
KBRAM, developers have plenty of space for application
code, communications stacks and data buffering. In
addition to the graphics capabilities, PIC32 MCUs also
have integrated peripherals for USB, CAN, Ethernet and
capacitive touch sensing.

PIC24F with Integrated Graphics Controller:
Low Cost, Easy to Use
The PIC24F DA family makes it easy and cost-effective to
add advanced graphics to your application by eliminating
the need for external frame buffers or display controllers.
■ On-chip display controller provides direct interface to
TFT, STN and OLED displays
■ Easy to use Graphics Processing Units for hardware
acceleration
• Move and copy rectangles with smooth, fast memory
transfers
• Decompress images without CPU intervention
• Render lines, bars and text without CPU intervention
■ Color look-up table and 96 KB RAM to support single
chip solution
• Color look-up table and 96 KB internal fram buffer to
support 8 bpp on QVGA applications
• Supports WQVGA 16 bpp with external frame butter
using PMP (Parallel Master Port)
With the hardware acceleration, this family is able to
process and render graphics without using any MCU MIPS.
The dedicated graphics engine is able to continuously drive
a display without being shared with any other function.
Graphical Display Configurations
External Graphics Controller: PIC MCU with Parallel Master Port (PMP)
PIC24, dsPIC® DSCs and PIC32 MCUs can also work with an external graphics controller to support larger screen sizes or
more advanced graphical features.
The Solomon Systech SSD1926 Graphics Controller has hardware graphics acceleration to free up the MIPS of the PIC
MCU. This controller includes a SD Card interface and JPEG decode engine as well as 256 KB RAM. The Graphics PICtail™
Plus SSD1926 Board (AC164127-5) includes serial Flash for data storage and interfaces to either Explorer 16 or PIC32
Starter Kits.
The Epson S1D13517 Graphics Controller includes alpha blending, picture-in-picture and supports up to WVGA
(800x480) at 24 bpp. This controller has an SDRAM interface for connection to low cost external memory. The Graphics
Controller PICtail Plus Epson S1D13517 Board (AC164127-7) includes 128 Mb SDRAM frame buffer and 16Mb serial
Flash and interfaces to either Explorer 16 or PIC32 Starter Kits.
