The reset timeout is a minimum of 140ms, which ensures the processor's oscillator and power rails have stabilized before the reset is released — a common requirement for MCUs and DSPs that need a clean start-up sequence.
No last-time-buy or obsolescence notice is in effect.
The MAX809 is a different device — typically a 3-pin reset generator with a single active-low output and no battery backup function. The MAX807NEPE has additional features (active-high output, battery backup switchover, 16-pin package) and is not a direct pin-compatible replacement. Check the respective datasheets for functional equivalence in your application.
The listed type is Battery Backup Circuit, functioning as an MPU supervisor with reset generation and battery backup switchover capability.
