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.
   
Dedicated graphics clock for a continuous, clean display
   
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 text without CPU intervention
   
Color look-up table and 96 KB frame buffer to support 
multiple colors
•    Supports QVGA 8 bpp with internal frame buffer
•    Supports WQVGA 16 bpp  with external frame buffer 
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                     
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 RAM for frame buffering
•    Supports QVGA 8 bpp with internal memory
•    Supports WQVGA 16 bpp with external SRAM  
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.
External Graphics Controller: PIC24 or 
PIC32 with Parallel Master Port (PMP)
PIC24 and PIC32 MCUs can also work with an external 
graphics controller to support larger screen sizes or more 
advanced graphical features. Many external graphics 
controllers are supported by the graphics library; a few that 
we support with development tools are highlighted below.
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 64 Mb serial Flash 
and interfaces to either Explorer 16 or PIC32 Starter Kits.
