Description: Working voltage: 3.3V-5V Working environment temperature: -40~85 degree 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. 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. 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. 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 Note: 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. Package included: 1* FT232H USB to JTAG UART FIFO SPI I2C Adapter
