The IAS acquires microscopic surface images via the lens and illumination system. The second byte contains the data. In addition, the SPI port should not be accessed during power down. Units are clock cycles.

Power Transistors RF Transistor.

The port pins may be shared with other SPI slave devices. The graph below shows sequentially acquired SQUAL values, while a sensor was moved slowly over white paper. It is always generated by the master the micro-controller.

This register contains the inverse of the revision ID which is located at register 0x It will take reads to upload the complete image. It is housed in an 8-pin staggered dual in-line package DIP.


Contact us to buy or sell excess electronic s320 parts and inventory. It can be in either state if the sensor is the only device in addition to the controller microprocessor.

The parameters of each mode are shown in the following table. These images are processed by the DSP to determine the direction and distance of motion. We are a franchised distributor of electronic components, as well as a sourcing and avvago agent for hard-to-find, obsolete, and allocated parts. The maximum register value is The maximum accumulator value is 28, but only bits [ Reports which mode the sensor is in. To improve communication reliability, all serial transactions should be framed by NCS.

Absolute value is determined by resolution. The solder fixture is needed to protect the sensor during the solder process.

We acago well known for our great prices, great selection, and as the leading online source for hard-to-find and hard-to-buy electronic component parts. PCB Assembly Considerations 3.

The minimum pixel value can vary with every frame. Bursts are terminated when NCS is raised.

Any write to this register will reset and arm the grabber to grab pixel 0 on the next image. The maximum pixel value can vary with every frame. Brands Line Card Manufacturers. The sensor automatically changes to the appropriate mode, depending qvago the time since the last reported motion Downshift Time.

Each mode has a different motion detection period, affecting response time to mouse motion Response Time. The data are latched into the output buffer after the last address bit is received.

It is subject to change when new IC versions are released. Design Considerations for Improved ESD Performance For improved electrostatic discharge performance, typical creepage and clearance distance are shown in the table below. Synchronous Serial Port The synchronous serial port is used to set and read parameters in the ADNS, and to read out the motion information.


After sending the register address, the micro-controller must wait tSRAD and then begin reading data. The optical position reference for the PCB is set by the base plate and lens.

Minimum Pixel value in current frame. Typical Distance Millimeters Creepage For product information and a complete list of distributors, go to our website: Reading clears the register. Read from this register to activate burst mode.

An external microcontroller reads the Dx and Dy information from the sensor serial port. The pixel sum value can change on every frame. Register 0x02 allows the user to determine if motion has occurred since the last time it was read.

The 1-Source Electronics group of companies provides a full suite of services to the electronics manufacturing industry. Write operations to RM1 and RM0 forces the sensor into rest mode.

This feature should not be used for power management during normal mouse motion. When the NCS pin is high, the inputs are ignored and the output is tri-stated.
