The port is a four wire serial port. Bursts are terminated when NCS is raised. The pixel sum value can change on every frame.

This register contains the inverse of the revision ID which is located at register 0x There is an aperture stop and features on the package that align to the lens.

When the NCS pin is high, the inputs are ignored and the output is tri-stated.

In addition, NCS must be raised after each burstmode transaction is complete to terminate burst-mode. Distance from lens reference plane to tracking surface Z. Recommended PCB mechanical cutouts and spacing. The written data byte is not saved. It has a new low-power architecture and automatic power management modes, making it ideal for battery, power-sensitive applications — such as cordless input devices. The minimum is 0. After sending the register address, the micro-controller must wait tSRAD and then begin reading data.

The maximum register value is It is housed in an 8-pin staggered dual in-line package DIP.

In addition, the SPI port should not be accessed during power down. This register contains the IC revision. SQUAL is typically maximized when the navigation surface is at the optimum distance from the imaging lens the nominal Zheight.


The sensor automatically changes to the appropriate mode, depending on the time since the last reported motion Downshift Time.

Y movement is counts since last report. Reading clears the register.


There MUST be a feature in the top case to press down onto the PCB assembly to ensure all components are interlocked to the correct vertical height. Insert the sensor and all other electrical components into PCB. The table below shows the state of the various pins during power-up and reset. Avago Technologies highly recommends the usage of burst mode operation in optical mouse sensor design applications.

The value avag this register does not change; it can be used to verify that the serial communications link is functional. Design Considerations for Improved ESD Performance For improved electrostatic discharge performance, typical creepage and clearance a20 are shown in the table below. Units are clock cycles. No load on MISO. If the MOT bit is set, then the user should read registers 0x03 and 0x04 to get the accumulated motion. Squal White paper 90 Squal value 80 70 60 50 40 30 20 10 0 1 Count Figure Power Transistors RF Transistor.

The pixel grabber captures 1 pixel per frame. For product information and a complete list of distributors, go to our website: An external microcontroller reads the Aago and Dy information w320 the sensor serial port.


The solder fixture is needed to protect the sensor during the solder process. In addition, it has an on-chip oscillator and LED driver to minimize external components. We are a a3220 distributor of electronic components, as well as a sourcing and procurement agent for hard-to-find, obsolete, and allocated parts.


Register 0x45 allows the user to change or monitor the rest mode configuration of the sensor. It will take reads to upload the complete image. Write operations to RM1 and RM0 forces the sensor into rest mode. Absolute value is determined by resolution. Care must be avaago to keep contaminants from entering the aperture.

X movement is counts since last report. Whatever your manufacturing need, come to 1-Source to buy electric components from the leading electronic component distributors and electronic component suppliers! The speed improvement is achieved by continuous data clocking to or from multiple registers without the need to specify the register address, and by not requiring the normal delay period between avqgo bytes.

Write Operation Write operation, defined as data going from the microcontroller to the ADNS, is always initiated by the avvago and consists of two bytes. There is long wakeup time from power down. Chip select input active low. These images are processed by the DSP to determine the direction and distance of motion.
