DLP-USB232R DLP Design

DLP- DLP- USB232R USB232R LEAD-FREE USB-SERIAL UART Module USB-SERIAL UART Module The DLP-USB232R is DLP Designs 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. FTDIs 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. Rev. 1.0 (November 2008) 1 DLP Design, Inc.
