General Purpose Multi Media Controller
1 Introduction
1.1 Features
The VM800B is a development module for
FTDI’s FT800, which is used to develop and
demonstrate the functionality of the FT800
Embedded Video Engine, EVE.
This module behaves as an SPI slave, and
requires a SPI Master for proper micro-
controller interfacing and system integration.
VM800B modules support 3 different LCD
panel size options and are designed for
industrial or commercial environments with
precision fitted bezels in either black (-BK)
or pearl (-PL).
VM800B35A-xx is the 3.5” LCD
VM800B43A-xx is the 4.3” LCD
VM800B50A-xx is the 5.0” LCD
The VM800B utilises the FTDI FT800
Embedded Video Engine, EVE. Graphic, audio
and touch features of the FT800 chip can be
accessed with the VM800B. For a full list of the
FT800’s features please see the FT800
datasheet. The VM800B has the following
features:
Ready to use LCD module.
Integrated with resistive touch screen LCD
panel
On board LCD backlight LED Driver
On board audio power amplifier and micro
speaker
Flexible power supply. Powering the
VM800B using either a 2.1mm power jack ,
SPI master connector or via USB Micro-B
port
5 V tolerant buffers when used with a 5V
SPI Master.
Precision fitted bezel in black(-BK) or pearl
(-PL)
Use of FTDI devices in life support and/or safety applications is entirely at the user’s risk, and the user agrees
to defend, indemnify and hold harmless FTDI from any and all damages, claims, suits or expense resulting
from such use.

Version Draft

The VM800B module is intended for direct use into existing applications that require a display. This
module is suitable for interfacing with an external microcontroller that has a SPI Master channel.
The VM800B module is available in multiple options: 3.5, 4.3 or 5.0 inch display options.
The main functions of the VM800B are as follows:
Micro USB, SPI connector
2-pin connector for power supply
3.3V regulator: Takes 5V input and outputs 3.3V for on-board circuits
LCD touch screen panel
5V tolerant buffers between the SPI master interface and the Slave interface of the FT800
o SPI timing requirements can be found in the FT800 datasheet. The on board level
converter buffers introduce additional delay. The actual maximum SPI clock frequency
depends on the host system timing and connection cable length to the VM800B PCB.
3 stage audio filter and power amplifier
8Ω speaker
Audio line out option
Precision fitted bezel
3.2 Physical Descriptions
3.2.1 PCB layout
The VM800B module PCB layouts are illustrated in Figure 3-4 and Figure 3-5. Boards are four-layer,
approximately 1.6 mm thickness.
