The 4-VDFN package measures 2.50 mm x 2.00 mm with a seated height of 0.90 mm, suitable for space-constrained PCB layouts in engine control units, infotainment, or ADAS modules.
Operating from a 1.8V to 3.3V supply, the oscillator accepts common logic rails without an external regulator — the 2.5V supply query is within this range and supported.
No stock-holding claim is made.
Yes, it is a direct functional replacement for a 12.5 MHz quartz crystal oscillator in CMOS logic systems. The MEMS resonator provides improved shock and vibration resistance, and the AEC-Q100 qualification makes it suitable for automotive environments where quartz may fail. The 4-VDFN package is a standard footprint; verify the pad layout matches your board.
The standby (power-down) current is 15 µA maximum, with the output disabled. Active supply current is 6.3 mA maximum.
The part is listed as RoHS compliant and lead-free per Microchip's standard material declaration. No separate certificate is held on this page; confirm with the datasheet or your compliance team.
