DLP- DLP- 2232H 2232H LEAD-FREE DUAL-CHANNEL HIGH-SPEED USB ADAPTER DUAL-CHANNEL HIGH-SPEED USB ADAPTER The DLP-2232H is DLP Designs premier USB-to-UART/FIFO interface module based on FTDIs 5th generation USB 2.0 High Speed (480Mb/s) silicon. The DLP-2232H is manufactured in a lead-free, RoHS-compliant, compact 40-pin, 0.1-inch spaced standard 0.6 inch wide DIP footprint. FEATURES: The DLP-2232H is drop in compatible with the DLP-2232M except for the difference in the VCCIO voltage. The DLP-2232H has a maximum VCCIO of +3.6 Volts, but as inputs its IO pins are +5.0 Volt tolerant. The DLP-2232H is shipped from the factory in DLP-2232M compatible mode. Refer to section 2.1 for mode select jumper configuration details. The DLP-2232H 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. Single channel synchronous FIFO mode for transfers up to 25 Mbyte/Sec. Enhanced bit bang mode interface option with read and write strobes USB to Fast Serial Interface mode provides a method of communicating with an external device over USB using 4 wires that can have opto-isolators in their path for galvanic isolation MCU host bus emulation mode uses both ports to emulate a standard 8048/8051 host bus CPU-style FIFO interface mode simplifies CPU interface design. FTDIs royalty-free Virtual Com Port (VCP) and Direct (D2XX) drivers eliminate the requirement for USB driver development in most cases. Rev. 1.1 (May 2011) 1 DLP Design, Inc. 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-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 -40C to 85C industrial operating temperature range.
