RPM873 is an infrared communication module for IrDA Ver. 1.2 (Low Power), featuring low power consumption and a small package. It integrates an infrared LED, PIN photo diode, and LSI, making it suitable for mobile devices.
The RPM873 module combines an infrared LED, PIN photodiode, LED driver and a receiver circuit in a single surface‑mount package. It supports the IrDA SIR low‑power standard (2.4 kbps to 115.2 kbps) and is intended for mobile devices such as cellular phones, PDAs, digital cameras and printers.
The datasheet provides absolute maximum ratings, recommended operating conditions, pin descriptions, electrical and optical characteristics, timing diagrams, and mechanical dimensions. Design notes advise layout practices to minimise noise and feedback, and include power‑down behavior and eye‑safety classification.
