DESCRIPTION
The SHARP GP2W0001YP is a standard trans-
ceiver module. Even at low operating voltages, it pro-
vides a reliable interface between logic and IR signals
for through-air, serial, half-duplex IR wireless data
links and is designed to satisfy IrDA physical layer
specifications.
The GP2W0002YP is the same module, and adds an
integral Electro-Magnetic Interference (EMI) shield.
While IR energy is inherently immune to EMI, the receiv-
ing devices themselves are not. This shield provides an
additional level of protection in electromagnetically noisy
environments such as PCs and other digital products.
The SHARP GP2W0001YP/GP2W0002YP infrared
transceiver modules contain a high speed, high effi-
ciency, low power consumption AlGaAs LED, silicon PIN
photodiode, and a low power bipolar integrated circuit.
The IC contains an LED driver circuit and a receiver, pro-
viding the Rx output. IrDA data rates of 2.4 kbit/s to
115.2 kbit/s are supported at both 20 cm and one-meter
distances. At the one-meter range, emitter current is
approximately I
F
= 300 mA and in the IrDA Low Power
Option communication mode I
F
= 27 mA. This dual
mode communication capability provides wider product
applications, such as a wireless data link with PCs,
PDAs, or any other IrDA compliant application already
on the market.
The GP2W0001YP/GP2W0002YP transceiver
modules may be operated over a power supply range
of 2.7 V to 5.5 V without any performance degradation.
This provides a single part with a wide variety of
design applications.
For power-conscious applications, the transceiver
module has a built-in Shutdown mode. This reduces
the receiver's current consumption to 1
A (MAX.) dur-
ing Shutdown. The transmitter and receiver circuits are
separate, allowing the transmitter LED to be driven
when in Shutdown mode.
OUTLINE DIMENSIONS
The dimensions shown in Figure 1 and Figure 2 are
only for design reference, and are subject to change
without notice. The metal shield case version
GP2W0002YP, (for excellent noise immunity) is shown
in Figure 2. Contact your local SHARP office for the lat-
est device specifications.

NOTES:
1. An in-band optical signal is a pulse/sequence where the peak
wavelength,
p, is defined as 850 nm < p < 900 nm, and the
pulse characteristics are compliant with the IrDA Physical Layer
2. See `IrDA Physical Layer Link Specification, Appendix A' for
ambient light conditions.
