3 / 12 page ![]() FLASH AS8F2M32 AS8F2M32 Rev. 2.7 01/10 Micross Components reserves the right to change products or specifications without notice. 3 *Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operation section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability. **Junction temperature depends upon package type, cycle time, loading, ambient temperature and airflow, and humidity (plastics).
