Embedded Artists 3.2 inch QVGA Touch Color LCD

3.2 inch QVGA Touch Color LCDThe QVGA LCD has integrated LCD controller with embedded display RAM and very flexible interface options: external 8-bit or 16-bit memory bus or serial (SPI-like) interface.

The display controller can directly interface the external memory bus of LPC22xx and LPC24xx, but it is also possible to emulate a memory interface with GPIO on the LPC21xx series. If a wide parallel bus is not feasible the serial bus can be used instead. The display update rate is a bit slower for a serial interface (since clock frequency can only be up to 10 MHz).

A simple 2x20 pin list (2.54mm pitch) + 1x6 pin list is used to interface the display.
