1 MP global-shutter CMOS imager for machine vision
The onsemi AR0141CSSM21SUEA0-TPBR is a 1/4-inch CMOS digital image sensor with a 1280H x 800 V active pixel array, delivering 1.0 MP resolution at 60 frames per second. The 3 µm x 3 µm pixel architecture supports global-shutter readout, making it suited for capturing fast-moving objects without motion blur in industrial inspection or barcode scanning. Operating from a single 1.8 V supply rail, the sensor integrates on-chip analog-to-digital conversion and programmable gain stages, reducing external component count in the camera module. The -30°C to 70°C temperature range covers indoor factory-floor environments and unheated outdoor enclosures.
Pixel architecture and readout timing
The 3 µm pixel pitch in a 1/4-inch optical format yields a diagonal of approximately 4.5 mm, allowing the use of standard M12 or S-mount lens families. The global-shutter pixel captures the entire frame simultaneously, eliminating the focal-plane distortion that rolling-shutter sensors exhibit on fast-moving targets. At 60 fps full-resolution readout, the pixel clock and data interface timing must accommodate a 74.25 MHz master clock typical for 720p-class sensors. The output is a parallel CMOS or serial MIPI CSI-2 interface depending on the configuration variant; the AR0141CSSM21SUEA0-TPBR is a specific orderable that should be verified against the target processor interface.
The package footprint requires a controlled-impedance routing for the MIPI differential pairs and a clean 1.8 V supply plane with local decoupling within 5 mm of the supply pins. Moisture sensitivity level (MSL) is typically MSL 3 for CSP packages; a pre-bake before reflow is recommended if the sealed bag humidity indicator card exceeds 10%.
