Board-fit and timing role
The Microchip DSC6011ME1B-032K768T is a fixed-frequency MEMS oscillator delivering a 32.768 kHz CMOS output — the standard frequency for real-time clocks, low-speed peripheral timing, and watchdog wake-up counters in automotive and industrial designs. The ±50 ppm frequency stability keeps the RTC drift under a few seconds per day — adequate for CAN bus time-stamping and sleep-cycle accuracy. Part of the DSC60XXB series, which covers multiple frequency options in the same 4-VFLGA footprint — a BOM consolidation play if the design uses several clock frequencies.
Power budget and standby operation
Draws 1.3 mA max during active oscillation — negligible in a system burning tens of mA. The 1.5 µA standby current means a 40 mAh coin cell can hold the RTC domain alive for over three years — useful for battery-backed automotive modules or IoT nodes that sleep most of the time.
Automotive-grade qualification and package
The land pattern uses a 0.50 mm pitch — the PCB layout engineer should match the recommended footprint in the datasheet for solder joint reliability. Supplied on Tape & Reel — standard for pick-and-place assembly.
