We report on a A 32/spl times/32 pixel CMOS imager with a digital pixel output fabricated in a 0.6 /spl mu/m CMOS process. The imager incorporates an embedded ALOHA MAC interface for unfettered self-timed pixel read-out in energy aware sensor network applications. Collision on the output is monitored using an analog contention detector. The imager has an unprecedented dynamic range of 240 dB for an individual pixel with an array dynamic range of 180 dB. The power consumption is 795 /spl mu/W for typical outdoor illumination conditions with a typical pixel mean event rate of 10 K samples/s with frame rate updates of 4.88 K frames/s.
