The MEMS resonator replaces a quartz crystal, giving it better shock and vibration tolerance versus a conventional crystal oscillator — useful in automotive and industrial environments where board-level mechanical stress is a concern. ## Standby function and supply flexibility A Standby (Power Down) pin cuts the supply current to 15 µA max when the clock is not needed, allowing the system to enter a low-power sleep state without a separate enable switch. The 7.2 mA max active current at 54 MHz is modest for a MEMS oscillator — the CMOS output swings rail-to-rail, so the load capacitance on the trace sets the actual dynamic power draw. The wide 1.8V–3.3V supply range means a single BOM line covers 1.8V, 2.5V, and 3.3V logic rails. No external level translator or dedicated regulator is needed when the oscillator is shared across a mixed-voltage clock tree. 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 DSC1001CI4-054.0000T fits standard 3.2 x 2.5 mm oscillator footprints. The no-lead construction means the solder joints are at the bottom pads — verify the PCB land pattern matches the package outline before layout; the absence of leads makes post-solder inspection reliant on X-ray or cross-section. Supplied in Tape & Reel (TR) packaging, the part is compatible with automated pick-and-place assembly. It is a current-production part suitable for new designs, and no pin-compatible replacement or successor has been announced.","metaTitle":"DSC1001CI4-054.0000T – Microchip MEMS XO, 54 MHz, CMOS","metaDescription":"DSC1001CI4-054.0000T from Microchip Technology: 54 MHz MEMS XO, CMOS output, 1.8-3.3V supply, -40°C to 85°C, AEC-Q100.
