That 13 mA saving matters in a battery-backed real-time clock or a low-power sensor node that gates the oscillator off between active cycles. ## Package footprint for layout The 6-pad footprint matches the standard MEMS oscillator land pattern — no exotic via-in-pad required. Surface-mount reflow compatible; the 0.90 mm height keeps it under low-profile shielding cans. ## Lifecycle status and sourcing No pin-compatible drop-in from the same family has been formally designated, so a board respin may be required for a long-term replacement.","metaTitle":"DSC8121CM2-PROGRAMMABLE MEMS XO, CMOS, -55 to 125°C","metaDescription":"Microchip DSC8121CM2-PROGRAMMABLE MEMS XO, CMOS output, 10-170 MHz, ±25 ppm stability, -55 to 125°C.
