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.
