UMFT220XA USB to 4-bit
SPI/FT1248 Development
Module
UMFT220XA is a USB to 4-bit SPI/FT1248 DIP module with a 0.3” row pitch.
Introduction
1
The UMFT220XA is a development module
for FTDI‟s FT220XQ, one of the devices
from FTDI‟s range of USB interface bridging
integrated circuit devices. FT220X is a USB
to 4-bit SPI/FT1248 (only up to 4 bit wide)
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
FT220X 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 UMFT220XA is a module which is
designed to plug into a standard 0.3” wide
16 pin DIP socket. All components used,
including the FT220XQ 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_000517
Features
1.1
The UMFT220XA is fitted with a FT220XQ; all
the features of the FT220X can be utilized with
the UMFT220XA. For a full list of the FT220X‟s
features please see the FT220X datasheet which
can be found by clicking here.
In addition to the features listed in the FT220X
datasheet, the UMFT220XA has the following
features:
Small PCB assembly module designed to fit a
standard 7.62mm (0.3”) wide 16 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 UMFT220XA 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 blob to produce a short. By default the UMFT220XA 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 ...
