2.9 – Enclosure Specifications
1. The enclosure for the CR821x should be large enough to
accommodate the engine and designed to maintain the ambient air
in contact with the CR821x within its operating limits (Note: special
care should be taken to ensure the temperature at the image sensor
does not exceed 70 ºC and the temperature at the processor does
not exceed 100 ºC). The enclosure should minimize infiltration by
airborne contaminants and foreign materials.
2. The CR821x must not come in contact with water.
3. The CR821x is sensitive to Electrostatic Discharge (ESD) and must
be handled appropriately. Any individual who handles the CR821x
should be grounded using a wrist strap and ESD protected work area
and work surface.
4. The warranty of the CR821x is void if the recommendations above
are not followed when handling or integrating the device.
