Overview
RPM871-H7 Photo Link Module IrDA Infrared communication Module RPM871-H7 RPM871-H7 is an infrared communication module for IrDA Ver.
1.
2 (Low Power).
The infrared LED, PIN photo diode, waveform shaping LSI are all integrated into a single package.
This module is designed with power down function and low current consumption at stand-by mode.
The ultra small package makes it a perfect fit for mobile devices.
!Features 1) Applied to IrDA version 1.
2.
(Low Power) 2) Designed for low power consumption at stand-by for receiving (Typ.
73µA).
3) Suitable for sets driven by battery due to power down control function.
4) Power supply voltage range : 2.
6V∼3.
6V 5) Constant LED load resistance can change communication range.
(Approx.
