The DLP-USB245R is DLP Design’s smallest USB-to-parallel FIFO interface module and

utilizes the popular FT245R IC with FTDIChip-ID? feature from FTDI. In addition to enabling

standard USB-to-FIFO designs, both asynchronous and synchronous bit-bang interface modes

are also available.

The DLP-USB245R is available in a lead-free, RoHS-compliant, compact 18-pin, 0.1-inch

standard DIP footprint.

FEATURES:

? Single-chip USB-to-parallel FIFO bidirectional data-transfer interface.

? Entire USB protocol handled on the FT245R; no USB-specific firmware programming is

required.

? Fully integrated 1024-bit EEPROM storing device descriptors and FIFO I/O configuration.

? Data transfer rates up to 1Mbyte per second.

? 256-byte receive buffer and 128-byte transmit buffer utilizing buffer-smoothing technology to

allow for high data throughput.

? FTDI’s royalty-free Virtual COM Port (VCP) and direct (D2XX) drivers eliminate the requirement

for USB driver development in most cases.

? Unique USB FTDIChip-ID? feature.

? Configurable FIFO interface I/O pins.

? Synchronous and asynchronous bit-bang interface options with RD# and WR# strobes.

? Device supplied preprogrammed with a unique USB serial number.

? Supports bus-powered, self-powered and high-power bus-powered USB configurations.

? Integrated level converter on FIFO interface for connection to external logic running at between

+1.8V and +5V.

? True 5V/3.3V/2.8V/1.8V CMOS drive output and TTL input.

? Configurable I/O pin output drive strength.

? Integrated power-on-reset circuit.

? Fully integrated power-supply filtering; no external filtering is required.

? +3.3V to +5.25V single-supply operation.

? Low operating and USB Suspend current.

? UHCI/OHCI/EHCI host-controller compatible.

? USB 2.0 full-speed compatible.

? -40°C to 85°C extended operating temperature range.
