The CMOS output and 3.3 V supply make it a drop-in clock source for MCUs, FPGAs, and serial transceivers that expect a standard square-wave clock. ## Standby power-down for battery-sensitive designs The standby (power down) function pulls the disable current to 1 µA max, while the active supply draws only 3 mA typical. In a battery-powered sensor node that sleeps most of the time, the oscillator's own draw during sleep is negligible — the 1 µA figure is below the self-discharge rate of a CR2032 coin cell.","metaTitle":"DSC1033AI2-012.0000T MEMS Oscillator – 12 MHz, ±25 ppm, CMOS","metaDescription":"Microchip DSC1033AI2-012.0000T – 12 MHz XO, MEMS resonator, CMOS output, 3.3 V, ±25 ppm stability, 1 µA standby.
