MCS7780
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.
MCS7780 operates in bus-powered mode. 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.
IrReady Qualified in Demo Adapters, Customer boards require IrDA qualification.
