DLP-USB1232H
|
|
|
The DLP-USB1232H is DLP Design’s premier USB-to-UART/FIFO interface module based
upon FTDI’s fifth-generation USB 2.0 High Speed (480Mb/s) silicon. The DLP-USB1232H is
available in a lead-free, RoHS-compliant, compact, 18-pin, 0.1-inch spaced standard DIP
footprint.
FEATURES:
The DLP-USB1232H has the capability of being configured in a variety of industry-standard
serial or parallel interfaces supporting these features:
• Entire USB protocol handled on the module; no USB-specific firmware programming required
• USB 2.0 High Speed (480Mbits/second) and Full Speed (12Mbits/second) compatible
• Multi-Protocol Synchronous Serial Engine (MPSSE) to simplify synchronous serial protocol
(USB to JTAG, I2C, SPI or Bit-Bang) designs
• RS232/RS422/RS485 UART transfer data rate up to 12Mbaud; the RS232 data rate is limited
by the external level shifter
• USB-to-parallel FIFO transfer data rate up to 8 Mbyte/sec
• CPU-style FIFO interface mode simplifies CPU interface design
• FTDI’s royalty-free Virtual Com Port (VCP) and Direct (D2XX) drivers eliminate the
requirement for USB driver development in most cases
• Adjustable receive buffer timeout
• Transmit and receive LED drive signals
• FT245B-style FIFO interface option with bidirectional data bus and a simple four-wire
handshake interface
• Asynchronous serial UART interface option with full hardware handshaking and modem
interface signals
• Fully assisted hardware or X-On / X-Off software handshaking
• UART interface supports 7/8 bit data, 1/2 stop bits and Odd/Even/Mark/Space/No Parity
• Auto-transmit enable control for RS485 serial applications using the TXDEN Pin
• Operational configuration mode and USB description strings configurable in on-board
EEPROM over the USB interface
• Configurable I/O drive strength (4, 8, 12 or 16mA) and slew rate
• Low operating and USB Suspend current
• Supports bus-powered, self-powered and high-power bus-powered USB configurations
• UHCI/OHCI/EHCI host-controller compatible
• USB bulk data transfer mode (512 byte packets in High Speed mode)
• +3.3V I/O interfacing (+5V tolerant)
• Extended -40°C to 85°C industrial operating temperature range
