RPM873

RPM873 Photo Link Module IrDA Infrared Communication Module RPM873 RPM873 is an infrared communication module for IrDA Ver. 1.2 (Low Power). The infrared LED, PIN photo diode, and 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. zFeatures 1) Infrared LED, PIN photo diode, LED driver and built-in receiver frequency formation circuit. 2) Applied to SIR (2.4 to 115.2kbps) low power standard. 3) Supply voltage range is from VCC=2.0 to 3.6V, VLEDA=2.6 to 5.5V. 4) Surface mounting type. 5) Built-in power down function. zApplications Cellular phones, PDA, DVC, digital still cameras, printers, handy terminals and etc. zAbsolute maximum ratings (Ta=25°C) Parameter Supply voltage Input voltage Operation temperature Storage temperature Power dissipation Symbol VCC/VLEDA Vin(5,6,7pin) Topr Tstg Pd Limits 7.0 ∗1 −0.3 to VCC+0.3 −25 to 85 −30 to 100 100 ∗2 Unit V V °C °C mW ∗1) This applies to all pins on the basis of ground pins (1,4pin). ∗2) In case of operating environment is over 25°C, 1.33mW would be reduced per each 1°C stepping up. zRecommended operating conditions (Ta=25°C) Parameter Supply voltage Symbol VCC VLEDA Min. 2.0 2.6 Typ. 3.0 3.0 Max. 3.6 5.5 Units V V Rev.B 1/6 RPM873 Photo Link Module zBlock diagram and application circuit AMP GND 1 2 NC VCC VCC AMP AMP 3 GND GND C1 4 POWER DOWN PWDOWN PWDOWN 5 RXD RXD 6 7 TXD TXD LEDA (LEDVCC) 8 ...
