IrDA Infrared Communication Module
GOverview
The RPM970-H14 Series is a module that corresponds to IrDA SIR/MIR/FIR (Low Power) standard. An
infrared LED, PIN photodiode, and LSI are all contained in a single subminiature package. This module is
designed for low power consumption while in waiting mode. Furthermore, it incorporates a power-down
function, thus making the module perfect for mobile sets.
GFeatures
1) Applied to IrDA SIR/MIR/FIR (low power).
2) Low power consumption while in waiting mode (800µA typical).
3) Incorporates a power-down function that is ideal for battery-powered applications.
4) Supports a wide voltage range of power supply from 2.4 to 3.6V.
5) The communications distance is changeable within an approximate rate between 20 and 50cm with the
