General Description
Ordering Information
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) crys-
tal oscillator. This combination of features allows signifi-
cant cost savings in system design along with straight
forward implementation of IrDa port functionality into PC
peripherals using the host’s USB port.
