IrDA Infrared communication Module
RPM871-H12
RPM871-H12 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) Infrared LED, PIN photo diode, LED driver & Receiver frequency formation circuit built in. Improvement of EMI noise
protection because of Shield Case.
2) Applied to SIR (2.4 to 115.2kbps)
3) VCC supply voltage range is from 2.6V to 3.6V.
4) Surface mount type.
5) Power down function built in.
6) Adjustable communication distance by LED load resistance value. (approximately 20cm to 60cm)
zApplications
Cellular phone, PDA, DVC, Digital Still Camera, Printer, Handy Terminal etc.
zAbsolute maximum ratings (Ta=25°C)
