Moreover, the CYONS1001x sensors are strategically designed to simplify assembly, reduce manufacturing costs, and improve yield. The sensor IC, vertical-cavity surface emitting laser (VCSEL), and laser driver are integrated in a single 8x8 QFN package with a self-aligning snap-on lens. Laser output power is calibrated before shipment to meet eye-safety standards. Consequently, there is no need for laser handling, laser power calibration, or optical alignment. Five versions of the CYONS1001x sensor are available, each with features designed for its target application. Optimized for gaming and other specialized high-performance applications, the CYONS1001U, CYONS1001G, and CYONS1001 combine unrivalled effective cursor speeds with continuously variable resolution to 3200 counts per inch (cpi) and independent resolution control in the x and y directions. The general purpose CYONS1001L and CYONS1001T, designed for desktop mouse and trackball applications, support two self-adjusting power down modes for extended battery life.

OptiCheck Optical Checkerboard CYONS1001U and CYONS1001G are the ideal solutions for high speed, high performance gaming mouse applications. CYONS1001 is designed to enable high precision and high accuracy tracking performance. The device is ideal for industrial control, noncontact digital measurement tools, graphics design peripherals, and other high precision motion-sensing applications. CYONS1001L is designed for desktop and mobile mouse applications. CYONS1001T is an elegant solution for low power, high precision trackball applications. There are three key advantages to the OptiCheck approach: OptiCheckTM Technology The OvationONS sensors use Cypress Semiconductor's patented OptiCheck technology -- a fundamentally different approach to laser navigation sensing. Instead of image capture and correlation, OptiCheck uses an "Optical Checkerboard" or array of light-sensitive elements connected in a patented, 2D comb detector configuration[1]. The outputs of the detector are amplified and combined in a unique arrangement to form four data outputs that completely describe the motion of the sensor. These four outputs are digitized and sent to a small digital signal processor to generate x and y location displacement data. Figure 1 shows the interconnection of the comb detector elements and the resulting four outputs. First, power consumption does not increase with an increase in tracking speed. OptiCheck requires only four data inputs to calculate x and y displacement, compared to the hundreds of inputs typically required for image correlation. OptiCheck therefore provides a much more efficient calculation. This increase in efficiency means the signal processing blocks have a negligible impact on power consumption, resulting in a system where current draw is nearly independent of speed. Second, tracking speed is independent of resolution. OptiCheck's processing requirements are independent of sensor resolution. This enables simpler and lower cost scaling for products that require both high speed and high resolution tracking performance. Third, the unique signal processing method employed by OptiCheck sensors enables continuously variable native resolution in the x and y directions independently. This unique capability offers application designers immense flexibility and freedom. Note 1. U.S. Patent No. 7,138,620, entitled "Two-dimensional Motion Sensor", describes aspects of this technology.

Two external components are required to isolate the analog and digital sections of the sensor and ensure proper analog power supply ramp time: a 22 F capacitor and a 10 nH inductor. Place decoupling capacitors at all power pins as close to the pin as possible. Figure 4 shows the recommended power and ground circuitry. Note that to meet laser safety requirements, the power supply voltage supplied to the sensor circuit must meet the operating conditions requirements specified in this document. Additionally, increasing the laser output power by any other means (hardware, firmware, or otherwise) can result in a violation of the Class 1 safety limit. Figure 4. Recommended Power and Ground Circuitry Document Number: 001-06398 Rev. *J Page 7 of 24 [+] Feedback CYONS1001x Power Management The CYONS1001x sensors are equipped with power management features designed to meet the needs of their target applications. The CYONS1001L and CYONS1001T sensors, which target general purpose tracking applications such as wireless mice, offer two power saving sleep modes that extend battery life, and an ultra low power hibernate mode that is used to meet USB suspend requirements. The CYONS1001, CYONS1001G, and CYONS1001U sensors are optimized for high performance applications that require fast response at all times; therefore, these devices only support hibernate mode. The operational modes supported by the CYONS1001x sensors are summarized in Table 7. The current consumption of each mode is listed in Table 5 on page 5. Table 7. Summary of CYONS1001x Operational Modes Mode Tracking Nap Sleep Hibernate CYONS1001, 1001G, 1001U Yes No No Yes CYONS 1001L, 1001T Yes Yes Yes Yes Hibernate Mode The controller can place the sensor in hibernate mode by asserting the SHUTDOWN pin. In this state, the sensor cannot detect motion, and can only be activated by resetting the SHUTDOWN pin to LOW. Startup time from hibernate mode to full tracking capability is 20 ms max. Passive Power Management The CYONS1001L and CYONS1001T sensors are ideal for passive power management. Unlike other laser sensors, these devices control their own low power modes, freeing the application designer from concerns about power minimization. No additional firmware is required to take advantage of their self-adjusting power-saving nap and sleep modes. Active Power Management For applications requiring further power reduction, mouse firmware can use the SHUTDOWN and MOTION pins to implement active power management. This means the controller actively switches the sensor between tracking and hibernate modes to reap the benefit of low current draw during hibernate mode. A typical requirement for a mouse is that mouse movement must be able to wake the system from a low power operating state. Though the sensor is unable to detect motion in hibernate state, firmware can be designed to periodically check for motion by temporarily bringing the sensor out of hibernation. A recommended approach to active power management is as follows: 1. Choose a motion-check period, such as once per second. Longer periods save more power, but also result in longer delays in detecting motion. 2. Assert the SHUTDOWN pin to put the sensor in hibernate mode. 3. At the start of each motion-check period, deassert the SHUTDOWN line, then wait until the sensor sets the MOTION line high (20 ms or less). 4. Send two read tracking data commands to the sensor, ensuring sufficient delay between the commands. The sensor reports zeroes in response to the first command to avoid sending spurious data. The second report has valid x-y data. 5. If the data is two counts or more for either x or y, the sensor has been moved and the controller must initiate its wakeup sequence. If the data is 1 count or less for both x and y, the sensor has not been moved and the controller can reassert SHUTDOWN until the next motion-check period. Tracking Mode In tracking mode, the sensor is in motion and tracking x/y changes. Tracking mode consumes the most power, with fast motion drawing slightly more current than slow motion. After approximately 4 seconds of inactivity, the sensor automatically switches to nap mode. Nap Mode In nap mode, the sensor can detect gross motion. If motion is detected, the sensor switches to tracking mode within 20 ms. If motion is not detected for 30 seconds after entering nap mode, the sensor automatically switches to sleep mode. Sleep Mode In sleep mode, the sensor can also detect gross motion. If motion is detected, the sensor enters tracking mode within 250 ms. If motion is not detected, the sensor remains in sleep mode indefinitely.

The resolution control capabilities of each sensor are summarized in Table 8. The various resolution control modes are described in the following sections. Setting Sensor Resolution Sensor resolution is controlled by the change resolution command described on page 11. Standard Resolution Control In standard control mode, resolution is adjusted in increments of 200 or 400 cpi, depending on the sensor. Standard resolution control requires a single change resolution command to change the resolution in both the x and y direction. X/Y resolution control requires a separate change resolution command for each direction. Fine resolution control requires two change resolution commands to specify the resolution. In both commands, the two most significant bits select the resolution control mode. In the first command, bits 5-0 provide the first half of the resolution code. In the second command, bits 5-0 provide the second half of the resolution code. X/Y Resolution Control In x/y resolution control mode, the x-direction and y-direction resolution are independent: they need not be set to the same value. Resolution in either direction is adjusted in increments of 50 cpi. Fine Resolution Control Fine control mode enables continuously variable resolution in increments of less than 1 cpi. Table 8.

The sensor is an SPI slave, and the external controller is the master. If the sensor is the only slave device, the controller can hold the NCS pin low at all times. The sensor SPI bus is configured as follows: overhead of this frequent command, no address byte is required, only a command byte. Tracking data is reported as relative movement since the last tracking data read. The tracking data is reported in two's complement format. Each time tracking data is read, the internal accumulators for both the x-axis and the y-axis are reset to zero. Bit order is MSB first The SPI bus clock input (SCK) must be between 500 kHz and 2 MHz CPOL = 0, the clock idle state is low CPHA = 0, data is registered as input on the leading edge of SCK and output on the trailing edge of the SCK Soft Reset Command The soft reset command forces the sensor into a soft reset. The reset takes the same amount of time as a power on reset of the sensor chip, so the external controller must wait approximately 100 ms before the sensor can respond to further commands. Test Write Command The test write command writes a data byte to sensor memory, where it is read back by the test read command. These commands enable the developer to test the SPI interface between the sensor and external controller. The sensor can process SPI commands when the MOTION pin is asserted by the sensor. The sensor cannot process SPI commands in nap, sleep, or hibernate mode. SPI Interface Commands Table 9 shows the format of the commands the external controller can issue to the sensor. Except for the change resolution and read resolution commands, the commands are identical for all for all CYONS1001x sensors. The commands are described in the following sections. Timing diagrams for the commands are shown on page 13. Test Read Command The test read command reads the test write data byte from sensor memory. If a test write command has not been issued before the test read command, the value returned is undefined. Read Firmware ID Command The read firmware ID command enables the controller to read a sensor firmware ID byte, allowing the system to maintain version control of firmware updates. The command is implemented as a read to the firmware ID address of the sensor. The byte returned by the sensor is a unique identifier of the firmware. Other than that, it is not structured. Read Tracking Data Command The read tracking data command reads four bytes of x/y axis location information in a single long transaction. To reduce the Table 9.

The command is implemented as a read to the product ID address of the sensor. The byte returned by the sensor is a unique identifier of the product ID. Other than that, it is not structured. .

The signal level returned by the sensor is not calibrated; yet, it can provide a useful measurement of signal level during system development. 5-0 Change Resolution Command The change resolution command enables the external controller to select the resolution of the tracking data reported by the sensor. The command consists of command byte, address byte, and data byte. The command and address bytes are the same for all CYONS1001x sensors; however, because the CYONS1001x have different resolution control capabilities, the interpretation of the data byte varies by sensor. Table 10 through Table 14 describe the configuration of the change resolution data byte for each CYONS1001x sensor. For a description of the resolution control modes, see "Resolution Control Capabilities" on page 9. Table 12.

The sensor responds with a data byte that matches the data byte in the last valid change resolution command. The interpretation of the data byte in the sensor's response to the read resolution command depends on the sensor and the resolution control mode the sensor is using. Table 10 through Table 13 describe the data bytes for each sensor. Because the response from the sensor includes only a single data byte and some resolution settings are specified by two data bytes, the controller must use a write-read, write-read sequence to access the two bytes required to specify resolution in x/y resolution control mode or fine control mode. if a read resolution command is sent before a change resolution command, the sensors respond with their default setting. .

The CYONS1001T only supports the x/y resolution control mode. A single change resolution command changes the resolution in either the x direction or y direction. Two commands are required to change the resolution in both directions. 4. In x/y resolution control mode, a single change resolution command changes the resolution in either the x direction or y direction. Two commands are required to change the resolution in both directions. 5. Fine resolution control mode requires two change resolution commands. In both commands, the first two bits select the resolution control mode. In the first command, bits 5-0 provide the first half of the resolution code. In the second command, bits 5-0 provide the second half of the resolution code. Document Number: 001-06398 Rev. *J Page 11 of 24 [+] Feedback CYONS1001x Table 13.

When the SHUTDOWN pin is asserted, the sensor quickly powers down and remains powered down until the pin is deasserted. When the SHUTDOWN pin is deasserted, the sensor returns to the default power up state after an internal wakeup sequence. Startup time from deassertion of the pin to full tracking capability is 20 ms max. The SHUTDOWN pin is asserted at any time except during the initial power on sequence or the wakeup sequence from a previous SHUTDOWN state. Table 15. SHUTDOWN Pin SHUTDOWN pin High Low Sensor Operating Mode Hibernate mode Tracking, nap, or sleep mode In addition, the MOTION pin serves as a startup indicator. The pin is asserted when the initial power on sequence or the wakeup sequence from SHUTDOWN state is complete. If the mouse is in motion during startup, the MOTION pin stays high; if the mouse is not moving, the MOTION pin goes low after 4 seconds. For the CYONS1001, CYONS1001G, and CYONS1001U only, the MOTION pin can also be used as an indicator of the sensor's readiness to report x/y data. For these models, the sensor pulls MOTION low when it is processing the Read x/y command, and set MOTION high again when it is ready to report data. Using this feature, designers can use the rising edge of the MOTION line as a signal to poll the sensor. This allows the mouse to poll the sensor at the highest possible rate. EXTCFG Pin The EXTCFG pin enables a factory test mode that manufacturers can use to verify laser output power for safety compliance purposes. The pin is held low by an internal 4K - 8K ohm pull down resistor, but is driven high to enable factory test mode. To enable factory test mode, drive the EXTCFG pin high at power up. When the power on sequence is complete, the sensor asserts the MOTION pin, indicating the device is ready to accept configuration data from the external controller over the SPI bus. The test command sequence is described in "Laser Output Power Test Procedure" on page 15. To re-enable the normal mode of operation after testing, set the EXTCFG pin low or no-connect at power up. Table 17. EXTCFG Pin EXTCFG pin High Low or NC Sensor Operating Mode Enables factory test mode Normal operating mode MOTION Pin The MOTION output reports the present operating mode of the sensor. When the MOTION pin is asserted, the sensor can process SPI commands. When the MOTION pin is deasserted, the sensor is in nap, sleep, or hibernate mode and cannot process SPI commands. Table 16.

This section provides guidelines for complying with the Class 1 emission requirements of IEC/EN 60825-1. Laser Output Power Test Procedure To verify the factory calibration, maximum output power is measured using the following procedure: 1. With power to the sensor off, drive the EXTCFG pin high, or temporarily tie the pin to DVDD. 2. Apply power and wait for the sensor to assert the MOTION pin. This indicates that the sensor is ready to accept configuration data from the external controller over the SPI bus. 3. Assert the SPI slave-select line and send the following configuration bytes to sensor through the SPI interface. A minimum delay of 50 s must be added between bytes. <0x03> <0x01> <0x00> <0x18> <0xFF> <0x02> <0x04> <0x00> <0xA7> <0x00> <0xFF> <0x00> The sensor locks the laser to the programmed power limit with continuous wave (CW) output. The sensor provides tracking data if queried, but the tracking performance is poor due to the test mode. After testing, the sensor must be power cycled with the EXTCFG pin low or not connected to ensure optimal tracking. Laser Output Power The CYONS1001x sensor package contains an integrated VCSEL and drive circuitry. Before shipping, Cypress adjusts the laser output power to eye-safe levels, taking into account specified variations in supply voltage, temperature, lens transmission, and VCSEL polarization, and factors such as VCSEL aging and test equipment accuracy. The output remains within eye-safe limits under reasonably foreseeable single-faults, as required by the IEC standard. From the perspective of a manufacturer, laser emission remains within the Class 1 limit, as defined in IEC 60825-1, Edition 1.2, 2001-08, provided the following requirements are met. The supply voltage applied to the sensor must be in the range of 2.7 to 3.6V. The operating temperature must be between 5 and 45 C. A CYONSLENS1001 must be properly installed over the sensor. Registration Assistance Cypress can provide assistance to customers who wish to obtain registration. Supporting documentation, including a verification test procedure to demonstrate end-product compliance with IEC and CDRH requirements is available. For further information, contact a Cypress representative. In addition, the following requirements must be met to prevent access to radiation levels that exceed the Class 1 limit: The laser output power must not be increased by any means, including firmware, hardware, or mechanical modifications to the sensor or lens. The sensor housing must be designed in such a way that the CYONSLENS1001 cannot be opened without the use of a tool. If the mouse is equipped with batteries, the housing must be designed to prevent access to laser energy when the battery cover is removed. It is the responsibility of the manufacturer to ensure these conditions are always met and to demonstrate end-product compliance to the appropriate regulatory standards. Document Number: 001-06398 Rev. *J Page 15 of 24 [+] Feedback CYONS1001x Firmware Update Capability In some cases, manufacturers may wish to use Cypress's MiniProg programmer to implement factory firmware updates. Firmware updates must be obtained only from a Cypress authorized representative. The Miniprog uses a 5-pin in-system serial programming (ISSP) protocol. By connecting the sensor's ISSP pins to the MiniProg, firmware is updated using Cypress PSoC(R) Programmer software. The most convenient way to connect the sensor pins to the MiniProg is to install a 5-pin male header on the board, routing Table 18. ISSP Pin Connections ISSP Pin Number 1 2 3 4 5 CYONS1001x Pin Number 29 30 5 19 17 Connector Pin Name DVDD GND XRES P1 [1] P1 [0] Function Power supply positive voltage Power supply ground connection Reset drive SCLK - serial clock SDATA - serial data IO the 5 pins to the sensor pins as shown in Table 18 and the schematic diagram in Figure 8. A suggested header is part number 22-23-2051 from Molex, Inc. To eliminate the expense of a 5-pin header, test pads may be included on the board, so that the ISSP connections are made with probes. MiniProg programmers and PSoC Programmer software are available for purchase and download at www.cypress.com. Figure 8.

Housing Design Safety Considerations The housing must be designed to ensure compliance with Class 1 laser safety standards. To prevent exposure to radiation levels that exceed Class 1 limits, the mouse must be designed such that it cannot be disassembled without the use of a tool. In Orientation of PCB in a Mouse Application Figure 9 shows the orientation of the sensor PCB in a standard mouse application. The sensor is mounted on a small PCB. Typically, the PCB is oriented sensor side down in the device housing. Figure 9. Sensor PCB Orientation Orientation of Sensor on PCB Figure 10 shows the correct assignment of "mouse UP," "mouse DOWN," "mouse LEFT," and "mouse RIGHT" motion. The UP and DOWN directions are reversed because the sensor side of the PCB faces down. Note that this diagram does not apply to the CYONS1001T sensor, which is typically mounted beneath a trackball. To maintain correct x/y orientation, the y report of the CYONS1001T is inverted (opposite sign) with respect to the other sensors. Figure 10. Orientation of Sensor on PCB Looking at lower side of sensor PCBA Mouse DOWN Sensor Illumination Aperture The illumination aperture must be properly sized to ensure light is not blocked as it enters or exits the sensor assembly. The minimum dimensions of the aperture are shown in Figure 11. Dimensions are in mm, referenced to the center of the lens alignment pin. Figure 11. Illumination Aperture Alignment holes Mouse LEFT Mouse UP Mouse RIGHT Document Number: 001-06398 Rev. *J Page 18 of 24 [+] Feedback CYONS1001x PCB Requirements Figure 12 shows the mechanical requirements for the PCB. The board requires: with the lens clips. The keepouts must be free of both components and solder build-up. Figure 13. PCB Keepout Zones Two clearance holes 1.00 mm in diameter for the lens alignment pins. Two slots for the clip legs of the lens. The radii of these slots are also 1.00 mm, giving the slot a width of 2.00 mm. The holes and the slots must be clear of other components on both sides of the PCB. Land pad architecture and spacing are consistent with JEDEC MO-220 (52-lead QFN). The L-shaped feature inside the array of lands must be soldered to the tab on the bottom of the sensor package and connected to the DGND signal of the PCBA. Also, the entire area within the sensor land pads must be kept free of exposed copper. Figure 12. PCB Mechanical Features PCB Mounting Height The distance between the tracking surface and the sensor must be controlled. For optimal performance, the lower edge of the PCB must be positioned 12.78 0.25 mm from the tracking surface, as shown in Figure 14. At this distance, the lower plane of the lens is typically 2.78 mm above the tracking surface. Deviations from the specified PCB-to-tracking surface distance degrade tracking performance and lift detection. Figure 14. PCB Mounting Height PCB CYONS1001 CYONSLENS1001 12.78 mm PCB Keepout Zones Figure 13 shows the PCB keepout zones. The keepouts on the sensor side of the board prevent interference with the CYONSLENS1001 lens after it is mounted on the sensor. The keepouts on the opposite side of the board prevent interference 2.78 mm (REF) TRACKING SURFACE Document Number: 001-06398 Rev. *J Page 19 of 24 [+] Feedback CYONS1001x Recommended Assembly Instructions Handling Guidelines To maximize yield and performance, follow the handling guidelines listed below. Manufacturing Process The CYONS1001x laser navigation sensors are designed to simplify the production process. Specifically, Do not touch the optical surfaces of the CYONSLENS1001. Hold lenses only by their outer edges. Do not allow debris or dust to enter the optical aperture on the top of the package. Do not remove the protective tape over the package openings until immediately before the lens is attached. Do not wash the sensor PCBA after the laser sensor has been installed. The protective tape prevents moisture and dust from entering the sensor; however, it is not designed to withstand pressurized washing fluids. The sensors are rated at 2kV ESD, so standard ESD practices are acceptable. The laser is integrated into the sensor package, so there is no need for laser handling, lead forming, or installation. The laser is precalibrated, so there is no need to adjust laser output power Figure 15. Handling Guidelines While different designs may require different manufacturing procedures, a recommended manufacturing process for a mouse is: 1. Collect sensor PCBA components (no need for select-at-test components). 2. Place laser sensor and passive components on sensor PCBA using a no-wash solder paste. 3. Solder components to PCBA. 4. Snap a CYONSLENS1001 lens over the laser sensor. 5. Install the laser sensor PCBA into the system housing. 6. Test and ship.
