ams’ NanEye Endoscopic Camera Reverse Engineering

SystemPlus publishes a reverse engineering of ams’ NanEye endoscopic camera:

"To achieve an exceedingly small size and minimal cost, the NanEye relegates memory and image processing functionality off-chip and uses low-voltage differential signaling to stream image data at 38 Mbps. The NanEye includes a wafer-level packaged (WLP) 1 x 1 mm2 249 x 250-pixel front-side illuminated CMOS image sensor designed by AWAIBA (acquired by ams in 2015) and WLO technology developed by Heptagon (acquired by ams in 2016). Through-silicon via technology connects the sensor to the 4-pad solder-masked ball grid array package on the backside, facilitating integration into novel imaging products. The camera can be ordered with several preset optical configurations with an F-stop range of F2.4 – 6.0 and a field of view (FOV) range of 90° – 160°. The version analyzed in this report has an F-stop of F#4.0 and FOV of 120°."

  1. I think this analysis is about the device generation that is around for some years now, right?

    there is a NaneyeM or NaneyeC around with 320x320 pixels.

    similarly, Optasensor uses such a sensor unter the brand "Osiris M": https://optasensor.com/

  2. What is the difference with the NanEye version we sampled 5 years ago?
    Does it provide the same poor performance?

  3. The analysis is of the Color NanEye2D. Though the exact optical configuration (NE2D_RGB_V120F4.0_2m) is not currently available in the ams shop, it is described in the most current datasheet and can be purchased from third party distributers.
