Mouse IC PAW3805EK and LED Lens Track-On-Glass Mouse Sensor

General DescriptionThe PixArt PAW3805EK-CJV1 is an optical sensor which isoptimized for infrared (IR) LED based wireless mouseapplication. It has high accuracy navigation ability thatenables navigation virtually on any flat surface, includingthe transparent glass. The low power architecture andautomatic power management make it suitable forpower-sensitive application such as a wireless mouse.PAW3805EK-CJV1 is capable of high-speed motiondetection up to the velocity of 40 inches/sec and 10g onnon-glass surfaces, 20 inches/sec and acceleration of 5gon glass surface. In addition, it has an on-chip oscillatorand a built-in programmable LED current driver. In orderto achieve the best tracking performance, it isrecommended to match the sensor with L029-LSI opticallens.Key FeaturesVirtually track on any flat surface, including glassUltra-low power consumptionInterface : 3-wire SPI (NCS, SCLK, SDIO)16-bit motion data length for X-movement and Y-movement Resolution up to 3000cpi with ~26cpi per stepMotion detection interrupt output Built-in Low Power Timer (LPT) for Sleep1/ Sleep2/Sleep3 modeProgrammable downshift time and sampling timeduring sleep modes Adaptive frame rate control for power saving duringmoving at different speeds Programmable LED Current Source (5-bits with1.2mA/step) to provide LED with constant current An infrared (IR) LED is integrated in the packageApplications Wireless mouse applicationsOptical navigation systems
