IrDA Infrared communication Module
RPM871
RPM871 is an infrared communication module for IrDA Ver. 1.2 (Low Power). The infrared LED, PIN photo diode, 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 waiting mode (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 transmission distance. (Approx. 20 to 60cm)
zApplications
Cellular phones, PDAs, etc.
