Product details

MEMS-based 32.768 MHz oscillator with AEC-Q100 qualification

Supply flexibility and package footprint

Operates from 1.8V to 3.3V supply — the wide input range covers 1.8V, 2.5V, and 3.3V logic rails without an external LDO, simplifying BOM consolidation across multi-voltage designs. Housed in a 4-SMD, no-lead package measuring 3.20 mm x 2.50 mm with a 0.90 mm seated height — a compact footprint that suits space-constrained automotive modules like telematics control units or sensor fusion boards.

Frequently asked questions

Is the DSC1001CI5-032.7680T AEC-Q100 qualified and RoHS compliant?

Yes, it carries AEC-Q100 automotive qualification, which includes reliability stress testing for temperature cycling, ESD, and latch-up. RoHS compliance is standard for Microchip's DSC1001 series.

Can the DSC1001CI5-032.7680T operate at 1.8V?

Yes — the supply voltage range is 1.8V to 3.3V, so it runs directly on a 1.8V rail without a separate regulator. The CMOS output swing tracks the supply voltage.

What does the standby (power down) function do on this oscillator?

When the standby pin is asserted, the output is disabled and the supply current drops to 15 µA max. This preserves power in battery-backed or intermittent-operation systems while allowing a fast restart to the 32.768 MHz output.

What is the closest pin-compatible alternative to the DSC1001CI5-032.7680T?

Within the DSC1001 series, other frequency variants share the same 4-SMD, no-lead package and pinout. For a direct 32.768 MHz replacement with different stability or temperature grade, check the DSC1001 family ordering guide — no single official second-source is listed.
