Rated AEC-Q100, this oscillator is qualified for automotive applications where shock, vibration, and thermal cycling exceed what a quartz resonator can tolerate — the MEMS resonator has no moving parts and no crystal to crack. ## Package, supply, and power — what fits where Housed in a 4-VFLGA package measuring 1.60 mm x 1.20 mm with a seated height of 0.89 mm, this oscillator occupies roughly the area of a 0805 resistor — critical for space-constrained ECU or sensor module layouts. Supply voltage range is 1.8 V to 3.3 V, covering common digital rail voltages without an extra regulator. Maximum supply current is 1.3 mA typical — low enough for always-on clock domains in battery-backed systems. The Enable/Disable function lets the system shut down the oscillator when the clock is not needed, reducing quiescent draw to near zero in sleep modes. This part is suitable for both new designs and production replenishment.","metaTitle":"DSC6003HI2B-027.0000T MEMS XO – AEC-Q100 27 MHz CMOS","metaDescription":"Active-production 27 MHz MEMS XO from Microchip, AEC-Q100 qualified, ±25 ppm stability, 1.3 mA supply, 1.6 x 1.2 mm VFLGA package.

The 4-VFLGA package is smaller than typical 5 x 3.2 mm or 7 x 5 mm quartz oscillators, so the PCB footprint must match the 1.6 x 1.2 mm land pattern.
