UMFT221XA USB to 8-bit
SPI/FT1248 Development
Module
UMFT221XA is a USB to 8-bit SPI/FT1248 DIP module with a 0.3” row pitch.
Introduction
1
The UMFT221XA is a development module
for FTDI‟s FT221XQ, one of the devices
from FTDI‟s range of USB to serial data
interface integrated circuit devices.
FT221X is a USB to SPI/FT1248 interface
with a battery charger detection feature,
which can allow batteries to be charged
with a higher current from a dedicated
charger port (without the FT221X being
enumerated). In addition, asynchronous
and synchronous bit bang interface modes
are available. The internally generated
clock (6MHz, 12MHz and 24MHz) can be
brought out on the CBUS pin to be used to
drive a microprocessor or external logic.
The UMFT221XA is a module which is
designed to plug into a standard 0.3” wide
20 pin DIP socket. All components used,
including the FT221XQ are Pb-free (RoHS
compliant).
Use of FTDI devices in life support and/or safety applications is entirely at the user‟s risk, and the user agrees
to defend, indemnify and hold harmless FTDI from any and all damages, claims, suits or expense resulting
Document Reference No.: FT_000518
Features
1.1
The UMFT221XA is fitted with a FT221XQ; all
the features of the FT221X can be utilized with
the UMFT221XA. For a full list of the FT221X‟s
features please see the FT221X datasheet which
can be found by clicking here.
In addition to the features listed in the FT221X
datasheet, the UMFT221XA has the following
features:
Small PCB assembly module designed to fit
a standard 7.62mm (0.3”) wide 20 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.
enable external power supply options and
variation of logic reference levels.

    ... Solder Link Modfications 5.2 The UMFT221XA has two solder links fixed to the top side of the PCB. These solder link can be adjusted by removing the solder linking the two PADs to produce an open or by placing a solder bridge to produce a short. By default the UMFT221XA has both solder links shorting their pads. To allow for enhanced flexibility of this module remove both solder links and wire the header pins according to the power setup required ...
