FRAMOS Offers Sony IMX536, IMX546, and IMX566 Sensors for New Standards in Factory Automation, ITS and Embedded Vision

Sony Semiconductor Solutions is continuing the current trend of offering sensors with better performance in smaller packaging. IMX536, IMX546,and IMX566 are the latest 4th generation 2/3-type formatCMOS sensors usingPregiusS^TMtechnology. With 8.1 megapixels,versionsare availablefor monochrome and for colour images (RGB).

The newCMOS sensorsin an identical LGA package feature a global shutter with variable charge-integration time. They achieve very good image quality with high sensitivity and low dark current characteristics. Thesesensors offer excellent opportunities to realise a simpler camera design – for example in factory automation, Intelligent Transport System (ITS) applications and embedded vision – with the IMX546 and IMX566 being particularly cost–efficient options.

TinyPixels withHighSaturation andSensitivity

Thanks to highsensitivity Backside Illuminated (BSI) pixel architecture, Sony® has been able to reduce the pixel size to 2.74µm on all three sensors. At the same time, the previous generation’s performance characteristics have been retained and even improved. With a size of just 11.1mm (diagonal) and 2.74µm pixels in a square pixel array with 8.13 M effective pixels (2856 (H) x 2848 (V)), the new IMX536, IMX546 and IMX566 sensors deliver the high saturation and sensitivity that are typicalforthePregiusSTMtechnology.

All sensors support multiple readout modes: all-pixel scan mode, vertical / horizontal 1/2 subsampling mode, 2×2 FD binning mode and various ROI settings.

The energy-saving sensors use a quadruple power supply design with 3.3V and 2.9V for theanalog, 1.1V for digital and 1.8V for interfacing.

ForIndustrialVisionSystems andEmbeddedApplications

The new IMX536 is the top model – a high-speed variant with SLVS/SLVS-EC interface allowing the sensor to achieve a frame and transmission rate up to 194fps with 8 bits in all-pixel scan mode. Because of its high frame rates, it is mainly used in demanding vision applications in factory automation. Monitoringfluidswhile filtering out microscopicdebrisis one such application.

The IMX546 also has an SLVS/SLVS-EC interface and achieves 91fps with 8 bits. Its resolution makes it suitable for all scenarios requiring Full HD displays, for example in factory automation and ITS. In turn, the attractively priced IMX566 is recommended for embeddedvision applications. Its image rate of 62fps with 8 bits and MIPI CSI-2 interface are ideal for controlling and processing image data in these settings.

Sibel Yorulmaz-Cokugur, sensor expert at FRAMOS,highlightsan important aspect ofthesensor design: “Sony usesPregiusSTMtechnology, a vertically stacked CMOS pixel architecture, to achieve better performance in an even smaller package.Stacked pixel architecture also makes it possible to put the signal processing on the chip, enabling further miniaturisation and enhanced sensor functionalities.”

StackedPixels in the BSIStructure

The main difference with the new stacked pixel technology is the positioning of the storage elements and the electrical wiring of the pixels. In this architecture, the pixel wiring is placed beneath the photodiodes. The pixel size can then be reduced to 2.74µm, while maintaining sensitivity and saturationquality. A higher resolution is also achieved.

CMOS sensors usingPregiusS^TMtechnologyoffer distortion-free, high resolution images, with a minimal package size. They are suitable for applications in manufacturing,inspection,and logistics – and achieve greater precision and faster processing speeds for smart factories and advanced automation.
