Datasheet
UMFT231XA USB to Full-
Handshake UART
Development Module
UMFT231XA is a USB to serial Full-Handshake UART DIP module with a 0.3” row pitch.
1 Introduction
1.1 Features
The UMFT231XA is a development module
for FTDI‟s FT231XQ, one of the devices from
FTDI‟s range of USB interface bridging
integrated circuit devices. FT231X is a USB
to UART 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 FT231X
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 of the on one of the
CBUS pin to be used to drive a
microprocessor or external logic.
The UMFT231XA is a module which is
designed to plug into a standard 0.3” wide
20 pin DIP socket. All components used,
including the FT231XQ are Pb-free (RoHS
compliant).
The UMFT231XA is fitted with a FT231XQ, all
the features of the FT231X can be utilized with
the UMFT231XA. For a full list of the FT231X‟s
features please see the FT231X datasheet
which can be found at the FTDI website.
In addition to the features listed in the FT231X
datasheet, the UMFT231XA 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.
20 pin DIP socket (0.3” wide and 0.1” pitch)
included with the evaluation module
package.
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.

4.4 CBUS Signal Options
The following options can be configured on the CBUS I/O pins. These options are all configured in the
internal MTP ROM using the utility software FT_PROG, which can be downloaded from the
www.ftdichip.com. The default configuration is described in Section 9.
CBUS Signal
Option
Available On
CBUS Pin
Description
Tristate
CBUS0-CBUS3
IO Pad is tristated
DRIVE_1
CBUS0-CBUS3
Output a constant 1
DRIVE_0
CBUS0-CBUS3
Output a constant 0
TXDEN
CBUS0-CBUS3
Enable transmit data for RS485
PWREN#
CBUS0-CBUS3
Output is low after the device has been configured by USB, then high during
USB suspend mode. This output can be used to control power to external logic
P-Channel logic level MOSFET switch.
NOTE: This function is driven by an open-drain to ground with no internal pull-
up, this is specially designed to aid battery charging applications. UMFT231XA
connects an external 47K pull-up.
TXLED#
CBUS0-CBUS3
Transmit data LED drive open drain pulses low when transmitting data via
USB.
RXLED#
CBUS0-CBUS3
Receive data LED drive open drain pulses low when receiving data via USB.
TX&RXLED#
CBUS0-CBUS3
LED drive open drain pulses low when transmitting or receiving data via USB.
SLEEP#
CBUS0-CBUS3
Goes low during USB suspend mode. Typically used to power down an external
logic to RS232 level converter IC in USB to RS232 converter designs. Cancel
SLEEP# option for when connected to a dedicated charger port, this can be
selected when configuring the MTP ROM. When this option is enabled SLEEP# is
driven high when FT231X is connected to a Dedicated Charger Port.
CLK24MHz
CBUS0-CBUS3
24 MHz Clock output.**
CLK12MHz
CBUS0-CBUS3
12 MHz Clock output.**
CLK6MHz
CBUS0-CBUS3
6 MHz Clock output.**
GPIO
CBUS0-CBUS3
CBUS bit bang mode option. Allows up to 4 of the CBUS pins to be used as
general purpose I/O. Configured individually for CBUS0, CBUS1, CBUS2 and
CBUS3 in the internal MTP ROM. A separate application note, AN232R-01,
available from FTDI website (www.ftdichip.com) describes in more detail how to
use CBUS bit bang mode.
BCD_Charger
CBUS0-CBUS3
Battery Charge Detect indicates when the device is connected to a dedicated
battery charger host. Active high output. NOTE: Requires a 10K pull-down to
remove power up toggling.
BCD_Charger#
CBUS0-CBUS3
Active low BCD Charger, driven by an open drain to ground with no internal
pull-up (4.7K on board pull-up present).
BitBang_WR#
CBUS0-CBUS3
Synchronous and asynchronous bit bang mode WR# strobe output.
BitBang_RD#
CBUS0-CBUS3
Synchronous and asynchronous bit bang mode RD# strobe output.
VBUS_Sense
CBUS0-CBUS3
Input to detect when VBUS is present.
Time_Stamp
CBUS0-CBUS3
Toggle signal which changes state each time a USB SOF is received
Keep_Awake#
CBUS0-CBUS3
Table 4.2 CBUS Signal Options
Active Low input, prevents the chip from going into suspend.
**When in USB suspend mode the outputs clocks are also suspended.
