Module
General Purpose Multi Media Controller
1 Introduction
The ME812A-WH50R is a development module for FTDI’s FT812, Embedded Video Engine (EVE)
graphics controller IC. This module behaves as an SPI slave, and requires a SPI Master for proper micro-controller interface and system integration.
The ME812A-WH50R module includes a 5.0 inch 800*480 TFT LCD panel with resistive touch screen, and an audio amplifier to drive 8Ω
speaker.
1.1 Features
The ME812A-WH50R module utilises the FT812, FTDI’s 2nd generation EVE chip. Graphic, audio and
touch functions of the FT812 can be accessed with the ME812A-WH50R. For a full list of the FT812’s features, please see the FT81x datasheet. The ME812A-WH50R has the following features:
Ready to use 5 inch WVGA LCD module.
Supports portrait and landscape display mode.
Bright backlight LED with dimming.
Supports resistive touch with pressure sensing.
Supports mono audio from FT812 or external source.
On board audio amplifier for driving an external 1W speaker.
+5.0V single power supply.
Support direct connectivity to MM900EV series modules as a display add-on.
Comes with bezel with four mounting holes for easy system assembly.

3 Board Interface Description
The ME812A-WH50R module is intended for direct use into existing applications that require a display.
This module is suitable for interfacing with an external microcontroller (e.g. MM900EV series) that has a
SPI Master channel (single, dual or quad data bus).

3.2 J2- SPI slave interface
J2 is an 8x2 pin header which provides power inputs and SPI slave interface signals. An MCU board with SPI master can easily add a display panel by connecting to the ME812A-WH50R through J2. If an
MM900EV series module is used, it can be directly plugged into J2 and secured with 4 standoff mounting holes.

Table 3-1 – J2 pin description
3.3 CN13- Audio connector
The ME812A-WH50R supports a mono speaker output through CN13. A PWM audio signal from the FT812 goes through a 3-stage RC filters and the audio amplifier, to drive the 8Ω speaker if connected. Maximum output power to the speaker is 1 Watt. A readymade speaker module (CleO-SPR1) is available from FTDI.
An alternative, mono line-in audio input is also provided on CN13. Users can drive in their own audio source to the on board power amplifier.

7 Application Example
7.1 Getting Start With an MM900EV Module
As a quick start with the ME812A-WH50R development board, connecting to an MM900EV module development platform is recommended. Demo applications are provided for users to experiment and experience the FT812 in the MM900EV+ME812A system. The following paragraphs provide a short description for development procedures.
The MM900EV series of FT900 MCU evaluation platforms allows users to develop various applications with rich peripheral interfaces. The following MM900EV modules are compatible:
MM900EV1A: with a 32-bit high performance FT900 MCU, 10/100Mbps Ethernet, USB2.0 Host, USB2.0 Device, SD3.0, Audio Codec, SPI Master Quad Interface, and 40-pin external GPIOs.
MM900EV-Lite: Tiny board with a 32-bit high performance FT900 MCU, USB2.0 Device,
SD3.0, SPI Master Quad Interface, and 40-pin external GPIOs.
Detailed information of MM900EV module can be found at: http://www.ftdichip.com/Products/Modules/MCUModules.htm
7.2 Hardware Setup
Figure 7-1 shows the ME812A-WH50R module connected to an MM900EV1A module.
