UMFT201XA USB to I2C
Development Module
UMFT201XA is a USB to I
2
C DIP module with a 0.3” row pitch.
1
Introduction
The UMFT201XA is a development module
for FTDI‟s FT201XQ, one of the devices from
FTDI‟s range of USB interface bridging
integrated circuit devices. FT201X is a USB
to I
2
C 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 FT201X
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 one of the CBUS pins
to be used to drive a microprocessor or
external logic.
The UMFT201XA is a module which is
designed to plug into a standard 0.3” wide
16 pin DIP socket. All components used,
including the FT201XQ are Pb-free (RoHS
compliant).
1.1
Features
The UMFT201XA utilises the FTDI FT201XQ; all
the features of the FT201X can be utilized with
the UMFT201XA. For a full list of the FT201X‟s
features please see the FT201X datasheet
which can be found by clicking
here.
In addition to the features listed in the FT201X
datasheet, the UMFT201XA 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 or USB
host 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.
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
from such use.

Description
Module Ground Supply Pins
3.3V output from integrated LDO regulator. This pin is decoupled with a 100nF
capacitor to ground on the PCB module. The prime purpose of this pin is to provide
the 3.3V supply that can be used internally. For power supply configuration details
see section 5.
+1.8V to +3.3V supply to the I
2
C Interface and CBUS I/O pins. For power supply
configuration details see section 5.
FT201X active low reset line. Configured with an on board pull-up and recommended
filter capacitor. When no power is applied to the USB bus, reset will be held low, this
prevents current from flowing to the host or hub when in self-powered mode.
Configurable CBUS I/O Pin. Function of this pin is configured in the IC‟s internal MTP
ROM. See CBUS Signal Options, Table 4.2.
Configurable CBUS I/O Pin. Function of this pin is configured in the IC‟s internal MTP

USB Cable Shield. Connected to GND via a 0ohm resistor.
5V Power output from the USB bus. For a low power USB bus powered design, up to
100mA can be sourced from the 5V supply and applied to the USB bus. A maximum
of 500mA can be sourced from the USB bus in a high power USB bus powered design.
Currents up to 1A can be sourced from a dedicated charger and applied to the USB
bus.
5V power input for FT201X. For power supply configuration details see section 5.
