UMFT221XE is a USB to 8-bit SPI/FT1248 DIP module with a 0.6” row pitch.
1 Introduction
1.1 Features
The UMFT221XE 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 UMFT221XE is a module which is
designed to plug into a standard 0.6” wide
20 pin DIP socket. All components used,
including the FT221XQ are Pb-free (RoHS
compliant).
The UMFT221XE is fitted with a FT221XQ;
all the features of the FT221X can be
utilized with the UMFT221XE. 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 UMFT221XE has the
following features:
 Small PCB assembly module designed to
fit a standard 15.24mm (0.6”) 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 jumpers.
The default jumper 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.

from such use.
