RPM872-H12 Photo Link Module IrDA Infrared communication Module RPM872-H12 RPM872-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. z Features 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) Surface mount type. 4) Power down function built in. 5) Low voltage operation as 1.5V of interface terminals to controller (TXD, RXD, Power down). z Applications Mobile phone, PDA, DVC, Digital Still Camera, Printer, Handy Terminal etc. z Absolute maximum ratings (Ta=25C) Parameter Symbol Limits Unit 1 Supply voltage Vmax 7.0 V Input voltage 0.3 to VIO+0.3 V Vin (5, 6, 7pin) Operation temperature Topr C 30 to +85 Storage temperature Tstg 30 to +100 C 2 Pd Power dissipation 100 mW 1 This applies to all pins basis ground pins (1.4pin) 2 In case operating environment is over 25C, 1.33mW would be reduced per each 1C stepping up. z Recommended operating conditions (Ta=25C) Parameter Symbol Min.
