Supply voltage range is 1.8V to 3.3V — a single order code covers 1.8V, 2.5V, and 3.3V rails. No need to stock separate voltage variants.
Housed in a 4-SMD, no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm max. The lands are on the bottom — no through-holes, no lead forming. Surface-mount only. The small footprint leaves room for adjacent decoupling caps on a tight layout. No exposed pad — the thermal path is through the solder joints to the board copper.
The DSC1001 series is Microchip's current MEMS oscillator family; no successor has been announced.
