MSM9405
IrDA Communication Controller
This version: JManS.M19994P80re5liminary
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.
