MS3201

The MS3201 from Novalog is an IrDA 1.0 and 1.2 compliant 115.2 kbps infrared transceiver module ideal for power sensitive personal data transfer applications. Setting a new industry benchmark the MS3201 will operate with the widest available supply voltage range, 1.5V to 5.5V. The MS3201 is also compliant with Sharp ASK/DASK and Consumer IR (TV Remote) specifications.

The MS3201 integrates an analog receiver, on-chip LED driver, IR photodiode, IR LED transmitter, and voltage filtering capacitor, Figure 1. Only one external current limiting resistor is required. This external resistor should be selected to optimize transmit distance and system power consumption. An external metal shield is utilized on the MS3201 for high EMI environments.
