GP2W0104YP

IrDA Data Sheet

115 kbps Transceiver

FEATURES

• Built-in Photodiode

• Operating voltage 2.4 V to 5.5 V

• Conforms to eye safety IEC60825-1, without exter-

nal resistor

• This product shall not contain the following materi-

als, and these materials shall not be used in the pro-

duction process for this product.

–CFCs

– Halon

– Carbon Tetrachloride

– 1.1.1. Trichloroethane (Methylchloroform)

– Specific brominated flame retardants such as the

PBBOS and PBBS are not used in this device.

INTRODUCTION

This specification applies to the outline and charac-

teristics of IrDA 1.2 type (data rate 2.4 kbps to 115.2

kbps, low power option compliant).

NOTES

• Caution should be taken to prevent the detector sur-

face from being smeared with dust or dirt, or from

being touched, as it may cause faulty operation.

• Cleaning conditions:

– Solvent cleaning: Solvent temperature 45°C or

less. Immersion for 3 minutes or less.

– Ultrasonic cleaning: The effect of ultrasonic

cleaning on the device differs by cleaning bath

size, ultrasonic power output, cleaning time, PCB

size or device mounting condition, etc. Test the

device under actual conditions and confirm that

ultrasonic cleaning does not cause any immedi-

ate or potential defects.

– Cleaning solvent: The cleaning shall be carried out

with ethyl alcohol, methyl alcohol, isopropyl alcohol.

• In order to prevent electrostatic damage to the inte-

grated circuit, handle this device in a static-free envi-

ronment and workstation.

• External force applied to the device after mounting can

cause mounting defects such as the terminal coming

off. Be careful when handling the device and prevent

objects from touching the device after mounting.

• Refer to the ‘Precautions for Soldering’ section.

• When the system (program) is designed, the turn

around time from transmit to receive should be

designed by considering 0.5 ms or more that is spec-

ified by IrDA. This turn around time means the time

that this device does not temporarily detect the

inconsistent signal, since the transmitted light from

the transmitter side reaches the detector side of the

same transceiver.

• When designing the system (program), consider that

0.3 ms or more (at TA = 25°C, no input signal) is nec-

essary to return from shut-down mode to ready-

operation mode. In addition, thoroughly confirm the

operation in the actual application.

• When there is considerable external stray light or a

light source is located near the transceiver, or the

detector face receives considerable external stray

light, a pulse other than signal output may be gener-

ated as noise on output terminal of the transceiver.

Consider the layout and structure in your design to

minimize disturbing light on the detector face.

• When the sensor is adopted in an IR communication

system, it should be used according to the signal

method which is specified by ‘Serial Infrared Physical

Layer Link Specification’ published by the Infrared

Data Association. Faulty operation may occur, if a sig-

nal method other than that specified is used.

• RXD pinout remains at high-level output in shutdown

mode. The RXD pinout is CMOS output, and other

CMOS outputs must not be directly connected to this

pinout, as it does not conform to tri-state output.

• In circuit designs, make allowance for the degradation

of the light emitting diode output that results from long-

term continuous operation (50% degradation/5 years).
