Sharp GP2W0002YP Low power infrared transceiver Datasheet

GP2W0001YP/GP2W0002YP
IrDA Technical Information
Low Power Infrared Transceiver
The GP2W0002YP is the same module, and adds an
integral Electro-Magnetic Interference (EMI) shield.
While IR energy is inherently immune to EMI, the receiving devices themselves are not. This shield provides an
additional level of protection in electromagnetically noisy
environments such as PCs and other digital products.
FEATURES
• IrDA 1.2a Low Power Option Compatible:
– IF = 27 mA (TYP.) for an operating distance of
20 cm
• Small Package Design for IrDA 1.0 Compliant Infrared Transceiver 8.7 (W) × 4.2 (D) × 3.15 (H) mm
• Receiver output provides a full output pulse for the
received input signal
• Fits within Mobile Phone Connector Dimensions
• Low Power Consumption and Built-in Shut-Down
Mode (1 µA MAX.)
• Wide Range of Operating Voltages provides power
supply design flexibility (VCC = 2.7 V to 5.5 V)
The SHARP GP2W0001YP/GP2W0002YP infrared
transceiver modules contain a high speed, high efficiency, 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, providing the Rx output. IrDA data rates of 2.4 Kbps to
115.2 Kbps are supported at both 20 cm and one-meter
distances. At the one-meter range, emitter current is
approximately IF = 300 mA and in the IrDA Low Power
Option communication mode IF = 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.
• SMD Package allows both Vertical and Horizontal
mounting on PCBs Description
For power-conscious applications, the transceiver
module has a built-in Shutdown mode. This reduces
the receiver's current consumption to 1 µA (MAX.) during Shutdown. The transmitter and receiver circuits are
separate, allowing the transmitter LED to be driven
when in Shutdown mode.
DESCRIPTION
OUTLINE DIMENSIONS
The SHARP GP2W0001YP is one of the smallest
transceiver modules. Even at low operating voltages,
it provides 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 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 latest device specifications.

Signal Waveform Example
Figure 14 shows examples of each waveform when
operating a GP2W0001YP to IrDA standards. Note that
the IrDA bitstream is inverted in the encoder and
decoder circuits, and the output pulse is sent during a
‘0’ bit. The examples are for reference only, to help
understand the GP2W0001YP hardware, and device
signal measurements. The receiver output is not gated,
and will send output for the entire period of the received
IR input signal. Refer to Figure 14 for waveform reference points.

GP2W0001YP transceiver module for best performance. All values in Figure 16 are for reference and
are in mm.

IrDA data transfer performance. The dimensions for W
can be calculated by the formula:
Figure 17 with its calculations illustrates the design
tips for a cabinet and an IR cosmetic window with ±18°
viewing angles in the vertical and horizontal axes. All
transceiver dimension values are for reference, and
are in mm.
The optical window size should be the minimum size
of W × H, either rectangular or elliptical, to maintain
W = 2 × L × tan(18 + w)
And the dimensions for H can be calculated by the
formula:
H = 2 × L × tan(18 +h)
In the case where the viewing angle is +18°, which
conforms to or exceeds the IrDA Serial Infrared Physical Layer Link Specifications. Values to be calculated
with above the formula must be given in mm.

Evaluation Board
Figure 18 shows the recommended evaluation circuit for the GP2W0001YP/GP2W0002YP devices. This
circuit is provided on an evaluation board for test and
evaluation purposes. Samples are available through
your Sharp support office or Sales Representative.
The resistor value for RL is based on the supply voltage. For the one-meter range, the parallel combination
of the three values should be adjusted to approximately
2.2 Ω when VCC = 3.3 V, yielding a forward current of
300 mA with approximately 200 mW being dissipated in
the resistors. For the 20 cm (reduced) range, the value is
adjusted to 33 Ω, the nominal forward current is 27 mA,
and the resistive power dissipation will be approximately
31 mW.
When the 33 Ω value and a forward current of 27 mA
is used, a total of 31.3 mW is dissipated during LED ontime. This dissipation is within the rating of the SR1206
package. When used at a data rate of 115 Kbps, the
maximum on time is 18.75% of a bit time when the LED
is ‘ON.’ Since only the logical ‘0’ values of a data string
are sent, the overall duty cycle is below this value.
The board carries three positions to allow the use of
a combination of standard resistor values. To create
the 2.2 Ω value, three 6.6 Ω resistors are connected in
parallel. For the 43 Ω value, one 43 Ω resistor can be
used or three parallel resistors of 130 Ω. The resistor
positions on the board are in the SR1206 footprint,
which supports one-quarter Watt resistors.
This test and evaluation board is not intended for
production applications, and should not be subjected to
long periods at elevated temperature. Operation of the
board should be limited to free-air test conditions.

MOISTURE-PROOF PACKING
INFORMATION
Scope
This section describes the specifications of
GP2W0001YP/GP2W0002YP moisture-proof packing,
and is only for reference. The official specifications
should be consulted for packing information.
Packing Material Specifications
The GP2W0001YP/GP2W0002YP reel is moistureproof packed for shipment. Table 3 describes the materials used for each item of the moisture-proof packing.
Packing Method
1. Seal the aluminum laminate bag that contains the
tape reel (2,000 devices/reel) and desiccant.
2. Fill in the necessary information on the label and
paste it on the aluminum laminate bag.
3. Pack 4 aluminum laminated bags (1 reel each) into
the designated outer case, placing paper pads on
the bottom and top of the outer case, as well as between each layer of the aluminum laminated bags.
See Table 4.
4. Seal the outer case with craft tape, indicating the
model name, quantity, and out-going inspection date
on the case. (8,000 pieces total per carton)
Storage and Treatment
STORAGE CONDITIONS
The product should be stored under these conditions:
• Storage temperature: 10°C to 30°C
• Humidity: below 60% RH
TREATMENT AFTER UNSEALING
1. After unsealing, devices should be mounted at a
temperature of 10°C to 30°C, humidity below 60%
RH, within 3 days.
2. For long term storage, devices should either be
stored in a dry box, or re-sealed in a moisture-proof
bag with desiccant and stored in an environment
where the temperature is 10°C to 30°C, humidity below 60% RH. Devices must be mounted within 2
weeks.
BAKING BEFORE MOUNTING
If the devices are not kept in the storage conditions
described above, or the desiccant indicator has turned
pink, baking must be performed before devices are
mounted: baking may only be done once.
• Recommended Baking Conditions: 100°C
12 to 24 hours
NOTE: Do not bake the devices while they are still on the reel — the
reel will melt. Parts should be either temporarily mounted to
a PCB with adhesive, or placed in a metal tray. Any device
that has been out of its dry pack for more than 72 hours
should be dried in some manner prior to any automated surface mount reflow process. Otherwise these devices should
be mounted and soldered by hand.
