USB2.0 high-speed to MPSSE SPI module VA800A-SPI is a small electronic circuit board
FTDI chip VA800A-SPIUSB 2.0 high-speed to MPSSE SPI
1. Introduction
USB2.0 high-speed to MPSSE SPI module VA800A-SPI is a small electronic circuit board, using FTDI [123 123 ] Ft232h .
The 10 -pin connector on the module is directly connected to the FTDI VM800B and VM800C graphics display modules. This allows to directly control the EVE FT800 device through the SPI interface of the USB host.All USB signals and protocols are processed on the module.

USB2.0 high -speed to MPSSE SPI module is a small electronic circuit board, using FT232H. The device processs all USB signals and protocols. This module provides a fast and simple way to connect a device with 3.3 volt digital interface to USB. For all detailed information about the integrated circuit, see the FT232H data table DS-FT232H.
The integrated FT232H device contains an command processor called a multi -protocol synchronous serial engine (MPSSE). The purpose of the MPSSE command processor is to communicate with equipment (such as JTAG, SPI, or I2C) in an efficient way. For details, see the MPSSE application instructions -An_.
This module is connected by the ten parent tube joints, and the parent tube joint can be connected with a parent tube jointEssence The pin signal conforms to CMOS logic at 3.3 volt.
FT232H is a single -channel USB 2.0 high -speed (480MB/s) to UART/FIFO IC. It can be configured on the serial or parallel interfaces of various industrial standards, up to 30Mbps, such as MPSSE-JTAG, SPI, I2C.
VA800A-SPI MPSSE module is only SPI configuration. The 10 -pin connector is directly installed on the VM800B and VM800C graphics display modules.
The module is powered by the USB host port and is compatible with USB2.0 high -speed compatibility.
The VA800A-SPI MPSSE module requires the USB device driver, which can be from
. The D2XX driver is used with the application software and directly access the FT232H in the module through DLL. As shown in Figure 2-1
VA800A-SPI MPSSE module uses FTDI's FT232H USB to serial IC device.
