The DLP-USB232R is DLP Design’s smallest USB-to-serial UART interface module, and it
utilizes the popular FT232R IC with the FTDIChip-ID™ feature from FTDI. In addition to
enabling standard USB-to-serial designs, both asynchronous and synchronous bit-bang
interface modes are available.
The internally-generated clock (6MHz, 12MHz, 24MHz and 48MHz) can be brought out of the
module and used to drive a microcontroller or external logic.
The DLP-USB232R is available in a lead-free (RoHS compliant), compact 18-pin, 0.1-inch
standard DIP footprint.
FEATURES:
• Single chip USB-to-asynchronous serial data-transfer interface.
• Entire USB protocol handled on the module; no USB-specific firmware programming is required.
• UART interface support for 7 or 8 data bits, 1 or 2 stop bits and odd/even/mark/space/no
parity.
• Fully-assisted hardware or X-On/X-Off software handshaking.
• Data transfer rates from 300 baud to 3 megabaud (RS422/RS485 and TTL levels) and
300 baud to 1 Megabaud (RS232).
• 256-byte receive buffer and 128-byte transmit buffer utilizing buffer-smoothing technology to
allow for high data throughput.
• FTDI’s royalty-free VCP and D2XX drivers eliminate the need for USB driver development in
most cases.
• Built-in support for event characters and line-break conditions.
• New USB FTDIChip-ID™ feature.
• New configurable CBUS I/O pins.
• Auto-transmit buffer control for RS485 applications.
• Transmit and receive LED drive signals.
• New 48MHz, 24MHz, 12MHz and 6MHz clock output signal options for driving an external
MCU or FPGA.
• FIFO receive and transmit buffers for high data throughput.
• Adjustable receive buffer timeout.
• Synchronous and asynchronous bit-bang mode interface options with RD# and WR# strobes.
• New CBUS bit-bang mode option.
