For new designs please use MCS7820

General Description

The MCS7720 controller provides bridging between the Universal Serial Bus (USB) input and two enhanced UART ports. This device contains all the necessary logic to communicate with the host computer via the USB bus.

In addition, the MCS7720 contains a 3.3V regulator and operates in bus-powered mode.

The MCS7720 has a reduced frequency (6MHz) 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.
