UMFT230XA USB to Basic

UART Development Module

UMFT230XA is a USB to Basic UART DIP module with a 0.3” row pitch.

1.1 Features

1 Introduction

The UMFT230XA is a development module for

FTDI’s FT230XQ, one of the devices from FTDI’s

range of USB interface bridging integrated circuit

devices. FT230X 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 FT230X 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 UMFT230XA is fitted with a FT230XQ; all the

features of the FT230X can be utilized with the

UMFT230XA. For a full list of the FT230X’s features

please see the FT230X datasheet which can be found

by clicking here.

In addition to the features listed in the FT230X

datasheet, the UMFT230XA 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.

The UMFT230XA is a module which is designed to

plug into a standard 0.3” wide 16 pin DIP socket.

All components used, including the FT230XQ are

Pb-free (RoHS compliant).

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.

Table 5.2 – Solder Links JP2 Pin Description

Note: There should never be more than one power output supplied to the same net. Failure to properly

remove solder from JP1 and JP2 can cause a direct short between two different power supplies (when a

self-powered set-up is applied and the USB bus is connected) resulting in damage to the UMFT230XA

module and the target circuit.

5.2 Solder Link Modifications

The UMFT230XA 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 UMFT230XA has both solder links shorting their pads. To allow for enhanced flexibility of

this module remove both solder links and wire the header pins accordingto the power setup required.

Figure 5.1 – Bus Powered Configuration

A bus powered configuration draws its power from the USB host/hub. The UMFT230XA is configured by

default to be in bus poweredmode.

Figure 5.1illustrates the UMFT230XA module in a typical USB bus powered design configuration. By

default solder bridge connections link VCCIO to 3V3OUT, and VCC to VBUS. (Note that Figure 5.1 is for

illustration only and that the pins do not actually go all the way throughthe PCB

For a bus power configuration power is supplied from the USB VBUS:

+5V VBUS power is sourced fromthe USB bus and is connected to the FT230X power input (VCC)

+3.3V power is sourced from the FT230X’s voltage regulator output and is connected to the FT230X IO

port’s power input (VCCIO).

Interfacing the UMFT230XA module to a microcontroller (MCU), or other logic devices for bus powered

configuration is done the same way as a self powered configuration (see Section 3), except that it is

possible for the MCU or external device to take its power supply from the USB bus (either the 5V from

the USB pin, or 3.3V from the 3V3OUT pin).

Figure 5.2 – Self-Powered Configuration

A self-powered configuration operates on the principle of drawing power from an external power supply,

as oppose to drawing power from the USB host. In this configuration no current is drawn from the USB

bus.

Figure 5.2 illustrates the UMFT230XA in a typical USB self-powered configuration. In this case the solder

links connection of JP1 is removed, which allows 5V power to be supplied to the module VCC pins from an

external source. VCCIO can to be powered from 3V3OUT or the VCC of an external source. (Note that

Figure 5.2 is for illustration only and that the pins do not actually go all the way through the PCB)

For a self-powered configuration it is necessary to prevent current from flowing back to the USB data

lines when the connected USB host or hub has powered down. To carry out this function the UMFT230XA

uses an on-board voltage divider network connected to the USB power bus and RESET# pin. This

operates on the principle that when no power is supplied to the VBUS line, the FT230X will automatically

be held in reset by a weak pull-down, when power is applied the voltage divider will apply a weak 3.3V

pull-up. Driving a level to the RESET# pin of the UMFT230XA will override the effect of this voltage

divider. When the FT230X is in reset the USB DP signal pull-up resistor connected to the data lines is

disconnected andno current can flow down the USB lines.

An example of interfacing the FT230X with a Microcontroller’s UART interface is also illustrated in Figure

5.2. This example shows the wire configuration of the transfer and handshake lines. This example also

illustrates that a voltage other than 3.3V can be supplied to the FT230X’s IO port, this feature is

described further and for bus poweredmode in Section 5.6.

Alternatively both the FT230X’s IO port and MCU can be powered from the 3V3OUT pin; this approach is

described in Section 5.5.

Figure 5.3 – Bus Powered with Power Switching Configuration

USB bus powered mode is introduced in Section 5.3. This section describes how to use this mode with a

power switch.

USB bus powered circuits are required by USB compliance standards to consume less than 2.5mA (and

less than 100mA when not enumerated and not suspended) when connected to a host or hub when in

USB suspend mode. The PWREN# CBUS function can be used to remove power from external circuitry

whenever the FT230X is not enumerated. (Note: It is impossible to be in suspended mode when

enumerated.) (Note that Figure 5.3 is for illustration only and that the pins do not actually go all the way

through the PCB)

To implement a power switch using PWREN#, configure a P-Channel Power MOSFET to have a soft start

by fitting a 10K pull-up, a 1K series resistor anda 100nF cap as shown in Figure 5.3. The time constant

Connecting the source of the P-Channel MOSFET to 3V3OUT instead of VBUS can allow external logic to

source 3.3V power from the FT230X without breaking USB compliancy. In this setup it is important that

the VCCIO is not sourced from the drain of this MOSFET, this is because the power used to drive the gate

of this transistor is sourced from VCCIO. VCCIO should be connected directly to 3V3OUT for this setup to

function effectively. It is also important that the external logic must and IO core of the FT230X must not

draw more that 50mA, this is because the current limit of the internal 3.3V regulator is 50mA.

Figure 5.4 – USB Bus Powered 3.3V Logic Drive

The FT230X can process signals at CMOS/TTL logic levels in the range of 1.8V to 3.3V. This section

describes how to utilise this feature.

Figure 5.4 shows a configuration where the FT230X is interfaced to a device with IOs operating in the

range of 1.8V – 3.3V. The IO ports of this module need to be powered with a voltage level that is equal

to the level of the signals it is processing. Since the FT230X’s embedded voltage regulator only outputs

3V3 the IO ports will need to be powered from another power source when operating at voltage levels

other than 3.3V. (Note that Figure 5.4 is for illustration only and that the pins do not actually go all the

way through the PCB)

By default, a short is present between 3V3OUT (embedded voltage regulator) and VCCIO (IO port’s

power input) by solder links JP1. If an external power supply is used to power the IO ports this solder

links needs to be open. This can be done by removing the solder linking the two pads of the solder links.

The configuration described in this section can be implemented in either bus-powered mode or self-

powered mode.

Note 1: The CBUS and DBUS pins are 5V tolerant; however these signals cannot drive signals at 5V

TTL/CMOS. VCCIO is not 5V tolerant; applying 5V to VCCIO will damage the chip.

12

UMFT230XA Datasheet

Version 1.4

Document Reference No.: FT_000519 Clearance No.: FTDI#269

Note 2: If power is applied to VCCIO and no power is applied to VCC all Ios will be at an unknown state,

this however will not damage the chip. The FT230X also has protective circuitry to prevent the chip being

damaged by a voltage discrepancy betweenVCCIO and the level of the signal being processed.

Note 3: When using VCCIO less than 3V3 on a chip from FTDI’s X-chip range, it is recommended to uses

pull up resistors (47K) to VCCIO on the data lines, all of the UMFT2xxXA devices include an on-board

pull-up for these lines.

5.8 Configuring the MTP ROM

The FT230X contains an embedded MTP ROM. This can be used to configure the functions of each CBUS

pin, the current drive on each signal pin, current limit for the USB bus and the other descriptors of the

device. For details on using the MTP ROM/EEPROM programming utility FT_PROG, please see the

FT_PROG User Guide and FT201X datasheet.

When programming the MTP ROM please note:

i) One of the CBUS Pins can be configured as PWREN# in the internal MTP ROM. This can be used to

switch the power supply to the external circuitry.

ii) The Max Bus Power setting of the MTP ROM should specify the maximum current to be drawn from

the USB host/hub when enumerated. For high-powered USB devices the current limit when

enumerated is between 100mA and 500mA, for low-powered USB devices the current limit is

100mA.
