1 Introduction

The UB232R is the smallest USB – serial development module in the FTDI product range. To minimise

the size of the module, the UB232R uses a standard USB mini-B connector. It is ideal for new

development purposes as well as a platform for adding a USB interface to existing product designs.

The UB232R is based on the FTDI FT232RQ USB to Serial UART IC which handles all the USB signalling

and protocols. The FT232R datasheet, DS_FT232R, is available at http://www.ftdichip.com, The

UB232R supports RTS/CTS hardware handshaking and is USB powered. The module supports data

transfer rates from 300 baud to 3 Mbaud (RS422, RS485, RS232 and at TTL levels). In addition, two of

the configurable CBUS pins of the FT232R are made available on the UB232R connector, allowing the

UB232R to provide clock signals to external logic or they can be used to drive signal traffic indicator

LEDs.

The UB232R is supplied with two 1x4 turned pin board headers with a standard 0.1” pitch. This aids rapid

prototyping and development. All components used, including the FT232R are Pb-free (RoHS compliant).

The UB232R requires USB drivers, available free from http://www.ftdichip.com, which are used to

make the FT232R on the UB232R appear as a virtual COM port (VCP). This then allows the user to

communicate with the USB interface via a standard PC serial emulation port (TTY). Another FTDI USB

driver, the D2XX driver, can also be used with application software to directly access the FT232R on the

UB232R though a DLL. This is illustrated in the Figure 1.1

Table 3.1 UB232R Module Connection

The signal output level on connectors J1 and J2 are controlled by the voltage supplied to the VCCIO pin 4

on the FT232R. The VCCIO is selected between the +5V (VCC from USB) or the output of the FT232R Low

Drop Out (LDO) +3.3V regulator. The VCCIO selection is done by fitting a link on connector J3. The

selection is shown in Table 3.2.
