UMFT240XA USB to 8-bit
245 FIFO Development
Module
UMFT240XA is a USB to 8-bit 245 FIFO DIP module with a 0.3” row pitch.
1 Introduction
The UMFT240XA is a development module for
FTDI’s FT240XQ, one of the devices from FTDI’s
range of USB to serial data interface integrated
circuit devices. FT240X is a USB to 245 FIFO
interface with a battery charging feature, which
can allow batteries to be charged with a higher
current from a dedicated charger port (without the
FT240X
being
enumerated).
In
addition,
asynchronous and synchronous bit bang interface
modes are available. The internally generated clock
(6MHz, 12MHz, 24MHz and 48MHz) can be brought
out of the on one of the CBUS pin to be used to
drive a microprocessor or external logic.
The UMFT240XA is a module which is designed to
plug into a standard 0.3” wide 24 pin DIP socket.
All components used, including the FT240XQ are
Pb-free (RoHS compliant).
1.1 Features
The UMFT240XA is fitted with a FT240XQ, all the
features of the FT240X can be utilized with the
UMFT240XA. For a full list of the FT240X’s features
please see the FT240X datasheet which can be found
at the
FTDI website.
In addition to the features listed in the FT240X
datasheet, the UMFT240XA has the following
features:
Small PCB assembly module designed to fit a
standard 7.62mm (0.3”) wide 24 pin DIP socket.
Pins are on a 2.54mm (0.1”) pitch.
On board USB ‘mini-B’ socket allows module to
be connected to a PC via a standard A to mini-B
USB cable.
Functionally configurable using solder links. The
default solder links setup enables the module to
function without peripheral wires or application
board. Other configurations enable external
power supply options and variation of logic
reference levels.
