Automotive-qualified 32.768 kHz MEMS oscillator for RTC and low-power timing
The DSC6003MI3B-032K768 is a MEMS-based XO (Standard) from Microchip's DSC60XXB series, delivering a 32.768 kHz CMOS output with ±20 ppm frequency stability over the full -40 to 85°C industrial/automotive temperature range.
Supply voltage flexibility and package footprint
Operating from 1.71 V to 3.63 V, this oscillator works from any common logic rail — 1.8 V, 2.5 V, or 3.3 V — without a dedicated LDO, simplifying the power tree on mixed-voltage designs. The 4-VFLGA package measures 2.00 mm × 1.60 mm × 0.89 mm — a compact footprint that fits space-constrained automotive modules and handheld devices.
