 MCS7780 -- USB 1.1 to IrDA Controller

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.

Feature:

  • 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 RoHS compliant
  • Operating temperature range: 0°C to +70°C
Target Applications:
  • High-Speed IrDA Communications
  • Cell Phone Interface Cable
