The DLP-USB1232H is DLP Design’s premier USB-to-UART/FIFO interface module based on
FTDI’s 5 th 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) design.
? RS232/RS422/RS485 UART Transfer Data Rate up to 12Mbaud. (RS232 Data Rate limited by
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 simple 4 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 TXDEN pin.
? Operational configuration mode and USB Description strings configurable in on-boardl
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.
