IC (supports Ver. 1.2 Low Power)
RPM870-H7
The RPM870-H7 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 a receiver frequency formation 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.
!Features
1) Supports IrDA Ver. 1.2. (Low Power)
2) Low power consumption while standing by for receiving (75µA 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.
