RPM871-H14
IrDA Infrared communication Module
RPM871-H14
RPM871-H14 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.
zFeatures
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 to 3.6V
5) Constant LED load resistance can change communication range. (Approx. 20 to 60cm)
zApplications
Cellular phones, PDAs, etc.
