IrDA Infrared Communication Module
RPM960-H14
RPM960-H14 is an infrared communication module for IrDA Ver. 1.3 (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 receiver frequency formation circuit built in.
Improvement of EMI noise protection because of Shield Case.
2) Applied to SIR (2.4k to 115.2kbps) and MIR (0.576,1.152Mbps).
3) Surface mounting type.
4) Power down function built in.
5) Adjustable transmission distance by LED load resistance value.
zApplications
Cellular phone, PDA, DVC, Digital still camera, Printer, Handy terminal and etc.
zAbsolute maximum ratings (Ta=25°C)

∗1) This applies to all pins on the basis of ground pin (8pin).
∗2) LED Peak Current : <90 µs, On duty < 25%
∗3) When glass-epoxy board (70x70x1.6mm) mounted. In case of operating environment is over 25˚C, 4mW
would be reduced per each 1˚C stepping up.

zNotes
1) LEDVCC (1pin), VCC (6pin) and VIO (7pin)
• Other power source can be used difference between LEDVCC and VCC and VIO. (VIO < VCC+0.3V)
2) Caution in designing board lay-out
To get maximum potential from RPM960-H14, please keep in mind following instruction.
• The line of RXD (4pin) should be connected at backside via through hole close to RPM960-H14 pin lead. Better not
to be close to photo diode side (8pin side).
⇒This is to minimize feedback supplied to photo diode from RXD.
• Better to be placed at more than 1.0cm radius from photo diode (8pin side) and also away from the parts which
generate noise, such as DC / DC converter.
• As for C1 between 6 and 8 pins, it should be placed close to RPM960-H14.
3) Notes
• Please be sure to set up the TXD (3pin) input to be “L” (under 0.6V) except transmitting data.
(For < 90µ sec. ON duty < 25%).
• Powerdown current might increase if exposed by strong light (ex. direct sunlight) at powerdown mode.
• Please use by the signal format which is specified by IrDA Ver1.3 (Low Power) except 4 Mbps.
There might be on error if used by different signal format.
4) Eye safe
• EN60825-1 (IEC60825-1 amendment2), Class1 Eye safe.
