UMFT51AA 8051
Compatible Module
UMFT51AA is an FT51A DIP module that is compatible with an 8051 microcontroller.
1 Introduction
The UMFT51AA is a development module for FTDI’s
FT51AQ, one of the devices from FTDI’s range of
microcontrollers with USB interface bridging features
integrated. FT51A is a MCU series which includes the
following features: USB client and USB hub
interfaces, 8051 core, 8-bit ADC, UART, SPI, I2C, 245
FIFO and PWM.
The UMFT51AA is a module which is designed to plug
into a standard 0.6” wide 40 pin DIP socket.
1.1
Features
The UMFT51AA is built with a FT51AQ; many of the
features of the FT51AQ can be utilized with this
module. For a full list of the FT51A’s series features
refer to the FT51A datasheet which can be found by
clicking here.
In addition to the features listed in the FT51A
datasheet, the UMFT51AA has the following features:

PCB assembly module is designed to fit a standard
15.24mm (0.6”) wide 40 pin DIP socket. Pins are
on a 2.54mm (0.1”) pitch. This module is a drop
in replacement for an 8051 microcontroller.

An on board USB type A socket and plug allow
modules to be connected to a PC via a standard A
extension cable or directly. This module is also
capable of cascading several modules by utilizing
the USB hub feature.

Debugger interface header used for debugging
and programming the FT51AQ. Designed for
operation with the FTPD-1 programmer /
debugger module. See the FTPD-1 datasheet for
details about this module.

Onboard jumper for configuring the FT51AA to be
in self powered or USB powered modes.
All components used, including the FT51AQ are Pbfree (RoHS compliant).

Bus-Powered mode. This setting creates a connection between VBUS and
VCC5V. For bus-powered operations 5V power will be output on CN2-1
when the module is connected to an upstream USB port.
Table 5.1 – Jumper JP1 Modes
Warning: There should never be more than one power output supplying power to the same net at any
one time. Closing JP1 will cause a direct short between two different power supplies, when a self-powered
set-up is applied and the USB bus is connected resulting in the potential for damage to the module and
other connected circuitry.
5.2
Programming Firmware to the Flash ROM
The FT51A can be programmed using the FTPD-1. CN3 is a dedicated port that can interface with the
FTPD-1.
A list of available examples (at time of writing) is shown below and source code can be found in
