RPM870-H14
The RPM870-H14 is an Module that supports IrDA Ver. 1.2 (Low Power), and is ideal for wireless communications.
An infrared LED, a pin-photo diode, and LSI are all contained in a very small single package. It is also equipped with low
power consumption and power down functions making this IC perfect for mobile sets.
zFeatures
1) Applied to IrDA Ver. 1.2. (Low Power)
2) Low power consumption while waiting mode. (90µA Typ.).
3) A power-down function is perfect for battery applications.
4) Supports a board power supply voltage range from 2.6V to 3.6V.
5) Only 1 external capacitor required.
