RPM841-H11 Photo Link Module IrDA Infrared Communication Module RPM841-H11 RPM841-H11 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) Super small package (W=6.8mm, D=2.44mm, H=1.5mm). 6) Infrared remote control transmission driver built-in. z Applications Mobile phone, PDA, DVC, Digital Still Camera, Printer, Handy Terminal etc. z Absolute maximum ratings (Ta=25C) Parameter Symbol Unit Limits Supply voltage Vmax 7.0 V 0.3 to VCC+0.3 V Input voltage Vin (3, 4, 5pin) Operation temperature Topr C 30 to +85 Storage temperature Tstg 40 to +100 C This applies to all pins basis ground pins (7pin) z Recommended operating conditions (Ta=25C) Parameter Symbol Min.
