GENERAL DESCRIPTION

The FT8U232AM is a cost-effective single chip USB UART ( U-UART ) solution for transferring serial data

over USB. With data transfer rates of up to 920k baud ( RS232 ) and 2,000 k baud ( RS422 / RS485 ) , the

FT8U232AM significantly raises the performance level above that above that of traditional ISA and PCI based

UART solutions whilst offering true plug and play and easy interfacing through it’s USB interface.

Its flexible architecture allows this IC to be used in many different application areas - USB modems,

Legacy RS232

USB Converter cables, USB interface cables for PDA’s , Bar Code Scanners , RS422 data links

and instrumentation – in fact almost any equipment that previously used a slow RS232 link for communication.

Virtual COM port drivers are available for the FT8U232AM for Windows ’98, Windows 98 SE and Windows

2000. Drivers for other operating systems are currently under development.

FT8U232AM - FUNCTIONAL BLOCK DESCRIPTION

•

3.3V LDO Regulator

The 3.3V LDO Regulator generates the 3.3 volt reference voltage for driving the USB transceiver cell

output buffers. It requires an external decoupling capacitor to be attached to the 3V3OUT regulator

output pin.

•

USB Transceiver

The USB Transceiver Cell provides the USB 1.1 full-speed physical interface to the USB cable. The

output drivers provide 3.3 volt level slew rate control signalling, whilst a differential receiver and two single

ended receivers provide USB data in, SEO and USB Reset condition detection.

•

USB DPLL

The USB DPLL cell locks on to the incoming NRZI USB data and provides separate recovered clock and

data signals to the SIE block.

•

6MHz Oscillator

The 6MHz Oscillator cell generates a 6MHz reference clock input to the X8 Clock multiplier from an

external 6MHz crystal or ceramic resonator.

•

X8 Clock Multiplier

The X8 Clock Multiplier takes the 6MHz input from the Oscillator cell and generates a 12MHz reference

clock for the SIE, USB Protocol Engine and UART FIFO controller blocks. It also generates a 48MHz

reference clock for the USB DPPL and the Baud Rate Generator blocks.

•

Serial Interface Engine ( SIE )

The Serial Interface Engine ( SIE ) block performs the Parallel to Serial and Serial to Parallel conversion

of the USB data. In accordance to the USB 1.1 specification, it performs bit stuffing / un-stuffing and

CRC5 / CRC16 generation / checking on the USB data stream.

•

USB Protocol Engine

The USB Protocol Engine manages the data stream from the device USB control endpoint. It handles the

low level USB protocol ( Chapter 9 ) requests generated by the USB host controller and the commands

for controlling the functional parameters of the UART.

•

Dual Port TX Buffer ( 128 bytes )

Data from the USB data out endpoint is stored in the Dual Port TX buffer and removed from the buffer to

the UART transmit register under control of the UART FIFO controller.

Future Technology Devices Intl. FT8U232AM Preliminary Information Rev 0.8 – Subject to Change

• Dual Port RX Buffer ( 384 bytes )

Data from the UART receive register is stored in the Dual Port RX buffer prior to being removed by the

SIE on a USB request for data from the device data in endpoint.

• UART FIFO Controller

The UART FIFO controller handles the transfer of data between the Dual Port RX and TX buffers and the

UART transmit and receive registers.

• UART

The UART performs asynchronous 7 / 8 bit Parallel to Serial and Serial to Parallel conversion of the data

on the RS232 ( RS422 and RS485 ) interface. Control signals supported by the UART include RTS, CTS,

DSR , DTR, DCD and RI. The UART provides a transmitter enable control signal ( TXDEN ) to assist

with interfacing to RS485 transceivers.

• Baud Rate Generator

The Baud Rate Generator provides a x16 clock input to the UART from the 48MHz reference clock and

consists of a 14 bit prescaler and 2 register bits which provide fine tuning of the baud rate ( e.g. to divide

by 2.5 ). This determines the Baud Rate of the UART which is programmable from 300 baud to 2 million

baud. For more details please contact FTDI.

• EEPROM Interface

Though the FT8U232AM will work without the optional EEPROM, an external 93C46 EEPROM can be

used to customise the USB VID, PID, Serial Number and Strings of the FT8U232AM for OEM

applications. The EEPROM is also required for applications where multiple FT8U232AM’s are connected

to a single PC as the drivers rely on a unique serial number for each device to bind a unique virtual COM

port to each individual device.
