MCS7703
The MCS7703 controller provides bridging between the Universal Serial Bus (USB) input and an enhanced UART port. This device contains all the necessary logic to communicate with the host computer via the USB bus.
In addition, the MCS7703 contains a 3.3V regulator and operates in bus-powered mode.
The MCS7703 uses single 12 MHz crystal oscillator. This combination of features allows significant cost savings in system design along with straightforward implementation of serial port functionality into PC peripherals using the host's USB port.
