E2F0007-18-11 ¡ Semiconductor ¡ Semiconductor MSM9405 IrDA Communication Controller el im This version: Jan. 1998 MSM9405 ina Pr ry GENERAL DESCRIPTION The MSM9405 is a communication controller conforming to IrDA, the international standard for infrared data communication. The device covers the IrDA physical specifications Ver.1.0 and 1.1. Since the device performs some of the functions concerning communication protocol control, the load on the software (firmware) for protocol control can be reduced. By combining the device with another microcontroller and an infrared transceiver module, a device provided with IrDA-compliant communication function can be configured.
