... The Avago Technologies ADNS-5020 is an entry-level, small form factor optical mouse sensor. It comes with many built-in features and optimized for LED-based corded products. The ADNS-5020 is capable of high-speed motion detection – ips and 2G. In addition, it has an on-chip oscillator and built-in LED driver to minimize external components. Frame rate is also adjusted internally. ...

... LED Mode For power savings, the LED will not be continuously on. ADNS-5020 will pulse the LED only when needed. Synchronous Serial Port The synchronous serial port is used to set and read parameters in the ADNS- 5020, and to read out the motion information. The port is a three wire serial port. The host micro-controller always initiates communication ...

... NOTE: The 0.5/f minimum high state of SCLK is also the minimum SDIO SCLK data hold time of the ADNS-5020. Since the falling edge of SCLK is actually the start of the next read or write command, the ADNS-5020 will hold the state of data on SDIO until the falling edge of SCLK ...

... Timing between Read and Either Write or Subsequent Read Commands During a read operation SCLK should be delayed at least t address data bit to ensure that the ADNS-5020 has time to prepare the requested data. The falling edge of SCLK for the first address bit of either the read or write command must be at least t ...

... READ FIRST BYTE FIRST READ OPERATION Notes on Power-up and Reset The ADNS-5020 does not perform an internal power up self-reset; the NRESET pin must be asserted low every time power is applied. There are two ways to reset the chip, either assert low NRSET pin or by writing 0x5a to register 0x3a ...
