The standby (power-down) function on this oscillator disables the output and reduces current draw to 1 µA max, letting the system clock gate without an external load-switch or GPIO-controlled enable. For a sensor node that wakes every 10 seconds to take a reading, the 3 mA active current runs for milliseconds while the 1 µA standby dominates the rest of the duty cycle — the average current stays well below 100 µA. ## Package and footprint for hand-solder and reflow Housed in a 4-SMD, No Lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm — a standard footprint that matches many quartz oscillator packages, so a board layout designed for a 5x3.2 mm can accepts this MEMS part without a spin. No hidden leads under the body.","metaTitle":"DSC1033BI2-012.0000T MEMS Oscillator – 12 MHz, CMOS, ±25 ppm","metaDescription":"Microchip DSC1033BI2-012.0000T: 12 MHz XO, MEMS resonator, CMOS output, ±25 ppm stability, -40°C to +85°C, 3.3V, standby function.

The DSC1033BI2-012.0000T outputs a rail-to-rail CMOS clock at 12 MHz, so it replaces a crystal + oscillator circuit or an external clock module in the same 5.0 mm x 3.2 mm footprint. No external load capacitors are needed — the MEMS resonator and drive circuit are inside the package."},{"question":"Does the DSC1033BI2-012.0000T have a standby or power-down function?","answer":"Yes, the part includes a standby (power-down) function. When the enable pin is driven low, the oscillator stops and the supply current drops to 1 µA max. The output goes into high-impedance state, allowing other clock sources to drive the line without contention."},{"question":"How can I order the DSC1033BI2-012.0000T or request a quote?","answer":"Submit an RFQ through this page with your target quantity and target price.
