GP2W0001

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. 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. 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. 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) • Solder Reflow Compatibility for automated production processes • SMD Package allows both Vertical and Horizontal mounting on PCBs Description DESCRIPTION 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.

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 IrDA data transfer performance. The dimensions for W can be calculated by the formula: 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.

Optical Window Tips Technical Information 11 GP2W0001YP/GP2W0002YP Low Power Infrared Transceiver 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. 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.

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. 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. 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) Table 3. Packing Materials ITEM Aluminum Laminate Bag Label Desiccant Outer Case Pads Paper Paper MATERIAL Aluminum Polyethylene Paper Storage and Treatment STORAGE CONDITIONS The product should be stored under these conditions: • Storage temperature: 10°C to 30°C • Humidity: below 60% RH Table 4.
