Product details

The DSC1001CI2-018.4320T: AEC-Q100 qualification qualifies it for automotive-grade applications — the MEMS resonator and CMOS output stage are rated to the same reliability stress and temperature profile as under-hood or cabin electronics.

Standby mode and current budget

This makes the part suitable for battery-backed or sleep-wake systems — the oscillator can be gated off between active bursts without a separate load-switch.

Package and lifecycle status

The no-lead package measures 3.20 mm × 2.50 mm with a seated height of 0.90 mm — a standard MEMS-oscillator footprint that reflows on the same land pattern as many quartz XO replacements.
