There are no moving parts, which means high reliability and less maintenance for the end user. Typical Distance Millimeters Creepage These images are processed by the DSP to determine the direction and distance of motion. This register contains the IC revision.

SQUAL is nearly equal to zero, if there is no surface below the sensor. The minimum pixel value can vary with every frame. They should be read consecutively. It will take reads to upload the complete image. Data subject to change. Schematic diagram for interface between ADNS and microcontroller cordless application. Care must be taken to keep contaminants from entering the aperture.

The table below shows the state of various pins during power down. The fixture should be designed to expose the sensor leads to solder while shielding the optical aperture from direct solder contact. Contact us to buy a3220 sell excess electronic component parts and inventory. The optical position reference for the PCB is set by the base plate avgo lens. We are a franchised distributor of electronic components, as well as a sourcing and procurement agent for hard-to-find, obsolete, and allocated parts.




Y movement is counts since last report. No load on MISO.

The 1-Source Electronics group of companies provides a full suite of services to the electronics manufacturing industry. NCS can also be used to reset the serial port in case of an error. In addition, the SPI port should not be accessed during power down. The shutter is adjusted to keep the average and maximum pixel values within a20 operating ranges.

Recommend to hold the PCB first vertically for the kapton removal process. The written data byte is not saved.

Read RM1 and RM0 for the sensor to report which mode it is in. If NCS is raised during a transaction, the entire transaction is aborted and the serial port will be reset. It has a new low-power architecture and automatic power management modes, making it ideal for battery, power-sensitive applications — such as avato input devices.

Bursts are terminated when NCS is raised. In addition, it has an on-chip oscillator and LED driver to minimize external components. Agago clears the register. When the NCS pin is high, the inputs are ignored and the output is tri-stated. Read from this register to activate burst mode.

Avgo can be in either state if the sensor is the only device in addition to the controller microprocessor. Register 0x45 allows the user to change or monitor the rest mode configuration of the sensor.


Power Transistors RF Transistor. The data are latched into the output buffer after the last address bit is received. Avago Avag highly recommends the usage of burst mode operation in optical mouse sensor design applications.

This register is the accumulated pixel value from the last image taken.

A320 wheel

There is an aperture stop and features on the package that align to the lens. Units are clock cycles.

The port is a four wire serial port. To improve communication reliability, all serial transactions should be framed by NCS. 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. The host micro-controller always initiates communication; the ADNS never initiates data transfers.

Avzgo solder the entire assembly in a no-wash solder process utilizing solder fixture. Write operations to RM1 and RM0 forces the sensor into rest mode. The value in this register does not change; it can be used to verify that the serial communications link is functional. Each mode has a different motion detection period, affecting response time to mouse motion Response Time.

Maximum Pixel value in current frame.
