For a battery-backed RTC or a sensor node that sleeps 99% of the time, this saves the energy a quartz oscillator would burn through its sustaining amplifier — the 3 mA active draw is already low enough for a coin-cell design, and the 1 µA sleep current extends shelf life without a load switch. No pin-compatible successor has been announced, so this order code is the current production choice for the 1.5 MHz, ±50 ppm, 3.3V CMOS slot.","metaTitle":"DSC1033AI1-001.5000T MEMS XO – 1.5 MHz CMOS, Standby","metaDescription":"Microchip DSC1033AI1-001.5000T MEMS oscillator: 1.5 MHz, CMOS output, ±50 ppm stability, standby power-down, -40 to 85°C, 3.3V.
