This is the under-hood or cabin-domain grade — the oscillator can be placed on the same board as the ECU's main processor without a separate derating analysis. ## Standby power-down for battery-backed systems In a telematics unit that sleeps between ignition events, this keeps the quiescent draw below the module's self-discharge budget — the MEMS resonator restarts in microseconds when the enable pin is asserted. Active-mode supply current is 6.5 mA max at 20 MHz, typical for a 1.8V–3.3V CMOS oscillator driving a 15 pF load. The MEMS base resonator consumes less power than a quartz crystal of the same frequency, which matters when the oscillator shares a 3.3V rail with a low-power MCU. Product status is Active, meaning Microchip continues to manufacture and support the DSC1004 series. ## 4-SMD no-lead package and board layout 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 footprint matches industry-standard 3.2 x 2.5 mm XO pads. The no-lead construction reduces parasitic inductance compared to a gull-wing package, which helps maintain clean clock edges at 20 MHz into a CMOS load.","metaTitle":"DSC1004CL2-020.0000T MEMS XO – 20 MHz, AEC-Q100, 1.8-3.3V","metaDescription":"Microchip DSC1004CL2-020.0000T: 20 MHz MEMS-based XO, CMOS output, ±25 ppm stability, -40 to +105°C, AEC-Q100.

The MEMS resonator gives faster start-up and better shock/vibration tolerance than quartz, but the electrical interface (enable pin, supply, ground, output) is identical.
