PMW3260DB-TPOU: Ultra Low Power LED Optical Mouse Sensor General Description The PixArt Imaging PMW3260DB-TPOU is a low power, small form factor optical mouse sensor. 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 PMW3260DB-TPOU along with the LM31-LNG lens, LED clip and HSDL -4261 IR LED form a complete and compact mouse tracking system. There are no moving parts and this translates to high reliability and less maintenance for the end user. In addition , precision optical alignment is not required, facilitating high volume assembly. Key Features  Small form factor molded lead frame 8 -pin PDIP package  Single low operating voltage: 1.70 – 2.00V  12-bits motion data registers  High speed motion detection 30ips and acceleration 10g  Motion detect pin output  Internal Oscillator – no clock input needed  3-wire SPI communication  Enhanced Programmability  Resolution up to 2000cpi  Downshift and wake up time  Sensor orientation

4.2 Layout Guidelines

 Insert the integrated sensor and all other electrical components into PCB.  Wave-solder the entire assembly in a no -wash solder process utilizing solder -fixture. A solder-fixture is required to protect the sensor from flux spray and wave solder.  Avoid getting any solder flux onto the sensor body as there is potential for flux to seep into the sensor package . The solder fixture should be designed to expose only the sensor leads to flux spray & molten solder while shielding the sensor body and optic al apertures. The fixture should also set the sensor at the correct position and height on the PCB.  Place the lens onto the base plate. Care must be taken to avoid contamination on the optical surfaces.  Remove the protective kapton tapes from optical apert ures of the sensor. Care must be taken to prevent contaminants from entering the apertures. Do not place the PCB with the sensor facing up during the entire product assembly process. Hold the PCB vertically when removing kapton tape.  Remove the protective kapton tapes from optical apertures of the sensor. Care must be taken to prevent contaminants from entering the apertures. Do not place the PCB with the sensor facing up during the entire mouse assembly process. Hold the PCB vertically when removing kapton tape.  Insert PCB assembly over the lens onto the base plate aligning post to retain PCB assembly. The sensor package will self-align to the lens via the guide posts. The optical position reference for the PCB is set by the base plate and lens. Note that the PCB motion due to button presses must be minimized to maintain optical alignment.  Install mouse top case. There must be a feature in the top case to press down onto the PCB assembly to ensure all components are stacked or interlocked to the correct vertical height
