The DSC1001DI1-004.0000T is a 4 MHz MEMS-based oscillator from Microchip's DSC1001 series, delivering a CMOS output across a 1.8V to 3.3V supply range.
Standby mode and supply flexibility
The wide 1.8-3.3 V supply rail means the same oscillator can serve a 1.8 V MCU core and a 3.3 V peripheral bus without a level translator.
The 4-SMD, No Lead package measures 0.098" × 0.079" (2.50 mm × 2.00 mm) with a seated height of 0.035" (0.90 mm). The small footprint and 0.50 mm pitch pads are compatible with standard reflow profiles; the MEMS die inside handles the 50,000 g shock rating typical of the DSC1001 family, so it survives board-level drop testing that would fracture a quartz resonator.
