Volver a DLP Design

DLP Design DLP-2232H Dual Channel High Speed USB Module

DLP Design Dual Channel High Speed USB Module is a USB-to-UART/FIFO interface module based on USB 2.0 high speed (480Mb/s) silicon. The DLP-2232H has a maximum VCCIO of +3.6 Volts, but its IO pins are +5.0 Volt tolerant as inputs. DLP Design Dual Channel High Speed USB Module is manufactured in a lead-free, RoHS-compliant, compact 40-pin, 0.1 inch spaced, standard 0.6 inch wide DIP footprint. 

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
  • 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
  • FTDI's 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-board EEPROM over the USB interface
  • Low operating and USB suspend current
  • Supports bus powered, self powered, and high-power bus powered USB configurations
  • UHCI/OHCI/EHCI host controller compatible

Specifications

  • 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
  • Configurable I/O drive strength (4, 8, 12 or 16mA) and slew rate
  • 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
