DLP-USB1 FEATURES

Send / Receive Data over USB at up to 1 M Bytes / sec

384 byte FIFO Transmit buffer / 128 byte FIFO receive

buffer for high data throughput

Simple interface to CPU or MCU bus

No in-depth knowledge of USB required as all USB

Protocol is handled automatically within the module

FTDI’s Virtual COM port drivers eliminate the need for

USB driver development in most cases.

Integrated 3.3v Regulator – No External Regulator Required

4.4v - 5.25v Single Supply taken directly from the USB port

UHCI / OHCI Compliant

USB 1.1 Specification Compliant

USB VID, PID, Serial Number and Product Description

Strings stored in on-board EEPROM.

Virtual COM Port Drivers for Windows 98, Windows 98 SE,

Windows 2000, Windows Millennium, Apple iMAC and Linux

GENERAL DESCRIPTION

The DLP-USB1 provides an easy cost-effective method of transferring data to / from a peripheral and a host at up to

8 Million bits ( 1 Megabyte ) per second. It’s simple FIFO-like design makes it easy to interface to any

microcontroller or microprocessor via IO ports.

To send data from the peripheral to the host computer simply write the byte wide data into the module when TXE#

is low. If the ( 384 byte ) transmit buffer fills up or is busy storing the previously written byte, the device takes

TXE# high in order to stop further data from being written until some of the FIFO data has been transferred over

USB to the host.

When the host sends data to the peripheral over USB, the device will take RXF# low to let the peripheral know that

data is available. The peripheral then reads the data until RXF# goes high indicating no more data is available to

read.

By using FTDI’s virtual COM Port drivers, the peripheral looks like a standard COM Port to the application

software. Commands to set the baud rate are ignored – the device always transfers data at it’s fastest rate regardless

of the application’s baud rate setting. The latest versions of the drivers are available for download from FTDI's

Drivers and Utilities page at http://www.ftdi.co.uk/.
