Its AEC-Q100 rating qualifies it for automotive applications where temperature cycling and vibration are routine — think engine-control modules, transmission controllers, or infotainment clocks that must hold timing through a cold crank and a hot soak. The MEMS resonator replaces a quartz crystal, giving it better shock and vibration immunity than a conventional crystal oscillator — a practical advantage on a board that sees the under-hood environment or frequent mechanical stress. ## Supply range, standby, and power budget It operates from 1.8V to 3.3V, so it can run off a 1.8V core rail or a 3.3V I/O rail without a separate regulator — the same BOM position serves both supply domains. Maximum active current is 7.2 mA, which keeps the thermal contribution low in a dense layout. The Standby (Power Down) function drops the disable current to 15 µA max. That lets the system gate the oscillator during sleep without a dedicated load switch, preserving battery life in portable or always-on automotive modules. ## Package, footprint, and lifecycle Housed in a 4-SMD, No Lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm — a compact footprint that fits into space-constrained designs like automotive sensor nodes or handheld instruments. The no-lead construction suits automated optical inspection and reflow soldering. Lifecycle status is Active. Sourced through independent distribution; quoted to order against the BOM quantity.","metaTitle":"DSC1001DE2-027.0000T MEMS XO, 27 MHz, CMOS, AEC-Q100, Active","metaDescription":"Microchip DSC1001DE2-027.0000T: 27 MHz MEMS XO, CMOS output, ±25 ppm stability, 1.8-3.3 V supply, AEC-Q100, -20 to +70°C.
