FT232H Block Diagram

Parameter

• Working voltage: 3.3V-5V

• Working environment temperature: -40~85degree

• Supports bus-powered, self-powered and high-power bus-powered USB configurations +1.8V (chip core) and +3.3VI/O interface (+5V withstand voltage)

• Use external EEPROM to save operating mode configuration and USB description string configuration data via USB interface

• Compatible with UHCI/OHCI/EHCI host controller; compatible with USB2.0 high speed 480Mbps and full speed 12Mpbs

• Support USB bulk data transfer mode (512-byte packets in high-speed mode) UART transfer data rate up to 12 megabaud (baud). (PS232 data rate limit is determined by external level shifter), UART interface supports 7 or 8 bit data bits, 1 or 2 stop bits and odd/even/marker/space/no parity

• Automatic transmission enable control for RS485 serial applications using the TXDEN pin

• USB to asynchronous 245 FIFO mode, transfer data rate up to 8 megabytes per second

• USB to synchronous 245 parallel FIFO mode, transfer rate up to 40 megabytes per second

• Supports half-duplex, bidirectional data bus, configurable width (1, 2, 4 or 8 bit wide) FT1248 interface

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

• Complete hardware grip or X-On/X-Off software

• Bit-bang with RD# and WR# control signal options; options for LED drive signals when transmitting and receiving

Typical Applications

• Single chip USB to UART (RS232, RS422 or RS485)

• USB to FIFO/FT1248/JTAG/SPI/I2C

• USB to Fast Serial Interface

• USB to CPU target interface (as memory) ·USB Instrumentation

• USB Industrial Control

• USB EPOS Control

• USB MP3 Player Interface

• USB FLASH Card Reader / Writers

• Set Top Box - USB interface

• USB Digital Camera Interface

• USB Bar Code Reader

Using

          After the board +5V pin is connected to the 5V power supply or inserted into the USB female port, since the LDO function is integrated in the chip, the +3.3V pin and the Vcore pin can be connected without external connection.
