FT51A-EVM Development
Module
FT51A-EVM is an FT51A development module with the following features: display, heart-rate monitor, temperature
sensor and force sensitive resistor.
1 Introduction
The FT51A-EVM is a development module for FTDI’s
FT51AQ, one of the devices from FTDI’s range of 8-bit
microcontrollers with USB interface bridging features
integrated. FT51A is a MCU which includes the
following features: USB client and USB hub interfaces,
8051 core, 8-bit ADC, UART, SPI, I²C, 245 FIFO and
P W M.
The FT51A-EVM demonstrates the FT51A series I²C
and SPI interfaces, the ADC input, PWM and GPIO
features. It contains a 28 pin header which allows easy
access to all the FT51AQ’s IO pins, as well as the
debug and reset pins. This module also comes
preloaded with the FT51A-EVM firmware that allows
users to use all the features of the module without
developing firmware.
1.1 Features
The FT51A-EVM is fitted with a FT51AQ; many of the
features of the FT51A series can be utilized with this
module. For a full list of the FT51A series features
please see the FT51A datasheet which can be found
by clicking here.
In addition to the features listed in the FT51A
datasheet, the FT51A-EVM has the following
features:
 20 X 2 characters, LCD display, with I²C interface
and RGB backlight.
 Heart-Rate Monitor with filtered and amplified
analogue output
 Force sensitive resistor
 SPI temperature sensor
 Push buttons controls and LED indicator
 Interface footprints to allow for communication with
FTDI’s FT8xx modules and TTL-232R cables
 Upstream and downstream USB ports w hich allow s
for direct connection cascading.
 Debugger interface header used for debugging and
programming the FT51AQ. Designer for operation
with FTPD-1. See FTPD-1 datasheet for details
about this module.
 Onboard jumper for configuring the module to be in
self pow ered or USB powered.
