The DSC1001DI2-029.5000T is a 29.5 MHz MEMS-based clock oscillator from Microchip's DSC1001 series, qualified to AEC-Q100 — the automotive IC reliability standard.
For a body controller or sensor module that sleeps most of the time, this idle current is low enough to skip a dedicated load switch — the oscillator's own disable pin handles the power gating.
No stock-holding claim is made; availability is verified per inquiry.
When the standby pin is asserted, the oscillator stops its internal MEMS drive and places the output in high-impedance. Supply current drops from 7.2 mA max to 15 µA max, preserving battery charge during idle periods. The output resumes within the start-up time after the standby signal is released.
Yes — it is a MEMS-based XO (standard oscillator) with CMOS output, so it drops into the same 4-pin, 2.5 mm × 2.0 mm no-lead footprint as a quartz oscillator. The AEC-Q100 qualification and ±25 ppm stability over -40°C to +85°C make it a suitable upgrade for automotive designs where quartz may suffer from vibration-induced frequency shifts.
