・Entire USB protocol handled on the chip. No USB specific firmware programming required.
・Interface options selectable via 3 mode select pins.
・7 GPIO lines interface option
・Basic UART interface with RXD, TXD, RTS, CTS pins option.
・TX_ACTIVE signal for controlling transceivers on RS485 interfaces.
・4 PWM channels option.
・I2C master interface option.
・SPI Slave interface option supporting modes 0, 1, 2 and 3 with MSB/LSB options
・SPI Master interface option supporting modes 0, 1, 2 and 3 with MSB/LSB options.
・USB error indicator pin
・Suitable for use on any Android platform supporting Android Open Accessory Mode (Typically 3.1 onwards, however some platforms may port Open Accessory Mode to version 2.3.4)
・12MHz oscillator using external crystal.
・Integrated power-on-reset circuit.
・+3V3 Single Supply Operation with 5V tolerant inputs.
・USB 2.0 Full Speed compatible.
・Extended operating temperature range; -40⁰C to 85⁰C.
