General Description The MCS7780 controller provides bridging between the Universal Serial Bus (USB) input and an IrDa wireless data communication port. This device contains all the necessary logic to communicate with the host computer via the USB bus. In addition, the MCS7780 contains a 3.3V regulator and operates in bus-powered mode. The MCS7780 has a reduced frequency (12MHz) crystal oscillator. This combination of features allows significant cost savings in system design along with straight forward implementation of IrDa port functionality into PC peripherals using the host's USB port.
