For a BOM destined for an under-hood ECU or a cabin-domain controller, that qualification removes the need for a separate reliability review.
Supply flexibility and standby power savings
The supply voltage range spans 1.8V to 3.3V — a single oscillator line item can serve a 1.8V-core MCU and a 3.3V peripheral bus without adding a second P/N. That simplifies the BOM and reduces procurement risk from a second-source gap.
Package and mounting for automated assembly
Housed in a 4-SMD no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — the same footprint as a standard quartz SMD oscillator, so no PCB layout change is needed when migrating from a quartz XO to this MEMS part.
The base product number DSC1001 covers a broad frequency family, so if a future BOM revision needs a different frequency, the same package and supply voltage apply — the change is a single P/N swap.
