1 Introduction
The VM800C 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.
VM800C modules support 3 different LCD
panel size options. Users can also connect to
different LCD screens as long as they meet
the FT800 technical specification and fit the
VM800C LCD connector.

The VM800C 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 VM800C module PCB comes in 2 types , 3.5 inch as well as a 4.3/5 inch model. The difference
between the 2 models is the flex cable receptical of the LCD. The 3.5 inch LCD uses a 54 pin receptical,
whereas the 4.3/5 inch model uses a 40 pin receptical.
The main functions of the VM800C are as follows:
Micro USB, SPI connector or 2-pin connector for power supply
3.3V regulator : Takes 5V input and outputs 3.3V for on-board circuits
LCD touch screen panel
LCD backlight driver. On board back light driver has over voltage protection (OVP).

5V tolerant buffers between the SPI master interface and the Slave interface of the FT800
o SPI timing requirement can be referred to FT800 datasheet. The on board level convert
buffers introduce additional delay. The actual maximum SPI clock frequency depends on
the host system timing and connection cable length to VM800C.

5 Hardware Setup Guide
5.1 Power Configuration
There are 5 methods of powering the VM800C board.
1) USB Power(5V) - Connect USB power through micro-USB cable to CN2
2) DC IN(5V) - Connect 5V to CN1
3) DC IN(3.3V) - Connect 3.3V to CN1 and short J5 pin 7 and 8
4) J5 Power(5V) - Connect 5V to J5 pin 7
5) *J5 Power(3.3V) - Connect 3.3V to J5 pin 7 and 8
*Warning: Applying 5 V accidently in this mode may cause permanent demage to the VM800C module.
The following table summarise how to power the VM800C board using the various methods.

5.2 MPSSE Setup
To give a quick start with the VM800C development board, a Windows based Sample Application and
demo applications are provided for users to experiment and experience the FT800 in the VM800C
system. The following paragraphs provide a short description for development procedures.
MPSSE is a “multi purpose synchronous serial engine” interface available in some FTDI device (e.g.
FT2232D, FT232H, FT2232H anf FT4232H). This engine allows users to bridge from a USB port on a PC to
an I2C or SPI interface. Sample code is available for driving the FT800 over this interface with a FT232H
device that has been integrated into a cable. This device is available in the VA800A-SPI board, or
C232HM-EDHSL-0(5V) cable or C232HM-DDHSL-0(3.3V) cable.
VA800A-SPI is a MPSSE module accessory which can connect to the VM800C modules directly. Detailed
information of VA800A-SPI can be found at:
http://www.ftdichip.com/VM800B.htm.
More information about MPSSE cables may be found at:
http://www.ftdichip.com/Support/Documents/DataSheets/Cables/DS_C232HM_MPSSE_CABLE.pdf.
In this section it is assumed the 5V version of the MPSSE cable (FTDI part no C232HM-EDHSL-0) is used.
In case a 3.3V version of the MPSSE cable (FTDI part no C232HM-DDHSL-0) is available, the setup is
similar except for the power pin connection. Refer to table 5-1 for board power configuration.

Figure 5-1 – VM800C connects to PC via VA800A-SPI or MPSSE cable.
Hardware Setup VA800A-SPI
Solder a 10 position single row pin header to J5 footprint of the VM800C board
Connect VA800A-SPI to the VM800C module in the correct orientation.
Connect USB cable (e.g. FTDI accessory VA-FC-1M-BKW or VA-FC-1M-BLW) from the VA800A-
SPI to the PC USB host port.
VA800A-SPI will supply power to VM800C after MPSSE driver is properly loaded and the USB host
completed USB device configuration.
Hardware Setup MPSSE Cable
Solder a 10 position single row pin header to J5 footprint of the VM800C board
Configure JP1 to either 3.3V or 5V
o Power Audio Amp by 3.3V : JP1 pin1 and pin 2 close
o Power Audio Amp by 5V : JP1 pin2 and pin 3 close (5V board supply must be provided)
Connect MPSSE leads to VM800C board’s J5( SPI interface) in accordance with Table 5-2
Plug MPSSE cable to PC USB port
Software Setup
Download PC Base MPSSE software. MPSSE cable and driver information can be found at
http://www.ftdichip.com/Products/Cables/USBMPSSE.htm.
Launch the Sample Application based on MPSSE from PC
For more information on utilizing the VM800C development system with the MPSSE cable and
Sample Application, refer to AN_245.
