What this MEMS oscillator brings to the board
You can drop it into an engine-bay ECU or a factory-floor PLC without second-guessing the temperature rating.
Standby power and the battery-life tradeoff
For a battery-powered sensor that sleeps 99 % of the time, the 15 µA standby current sets the floor for the sleep-state power budget. Compare that to a quartz oscillator of the same frequency: the MEMS part typically runs cooler and uses less peak current, which matters when the regulator feeding it is already sized for the MCU core.
Package, footprint, and production status
Housed in a 4-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm – the same footprint as a standard quartz 3.2 x 2.5 mm oscillator, so no board layout change is needed to swap from quartz to MEMS. Lifecycle status is Active – Microchip has not issued a PCN or end-of-life notice.
