MCS7780

MCS7780 USB 1.1 to IrDA Controller Features USB Specification 1.1 Compliant. Supports all USB Standard Commands. Full Compliance to IrDA 1.4 WHQL Certified Low-Power CMOS Design Powered from USB port Single 12 MHz Crystal IrDA Data Rates from 2.4 Kbps to 115.2 Kbps in SIR mode Supports MIR (Medium IR) at 1.152 Mbps Supports FIR (Fast IR) mode with Data Rate of 4 Mbps Uses Standard IrDA Transceivers LED Driver capable of 650 mA @ 5V, 25% Duty Cycle Low-Profile 28-Pin SSOP Package 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. The MCS7780 operates in Bus-Powered mode, and uses 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.
