AEC-Q100 qualified and rated across -40°C to 125°C, this part is built for under-hood and engine-bay environments where the ambient temperature swings hard and the supply sees transients. The qualification means it has passed the stress tests automotive OEMs require — no extra screening needed for a production ECU or a body controller BOM.
Active lifecycle status per the manufacturer — no end-of-life notice, no last-time-buy clock.
Yes, it is AEC-Q100 qualified and rated for -40°C to 125°C operation, making it suitable for automotive under-hood and industrial applications.
The reset timeout is 140ms minimum, which ensures the processor stays in reset long enough for the supply rail to settle after power-up or a brownout.
