RPM972-H14 Photo Link Module IrDA Infrared Communication Module RPM972-H14 RPM972-H14 is an infrared communication module for IrDA Ver. 1.4 (Low Power). The infrared LED, PIN photo diode, and waveform shaping LSI are all integrated into one single package. This module is designed for low power consumption. The very small package makes it a perfect fit for mobile devices. Also it provides the capability of IR remote control transmission for universal remote control applications. z Features 1) Infrared LED, PIN photo diode, LED driver and receiver frequency formation circuit built in. Improvement of EMI noise protection by Shield Case. 2) Applied to SIR (9.6k to 115.2kbps), MIR (0.576M, 1.152Mbps) and FIR(4Mbps). 3) Surface mount type. 4) Power down function built in. 5) Adjustable communication distance by LED load resistance value. 6) Infrared remote control transmission driver built-in. z Applications Cellular phone, PDA, DVC, Digital still camera, Printer, Handy terminal etc. z Absolute maximum ratings (Ta=25C) Parameter Symbol Limits Unit 1 Supply voltage Vcc / VLEDA / VIO 6.5 V Input voltage Vin(3,4,5pin) 0.3 to VIO+0.3 V Operation temperature Topr 25 to 85 C Storage temperature Tstg 30 to 100 C 1) This applies to all pins basis ground pin (8pin). z Recommended operating conditions Parameter Symbol Min.
