Its MEMS resonator construction gives it better shock and vibration tolerance than a quartz crystal — a meaningful advantage in automotive and industrial environments where board flex or engine vibration can pull a quartz oscillator off frequency. ## AEC-Q100 qualification and temperature range The industrial temperature band also covers outdoor telecom, factory-floor controllers, and engine-bay electronics where a standard commercial oscillator would drift or fail. ## Standby mode and supply flexibility A standby (power-down) function drops supply current to 15 µA max when the enable pin is pulled low — useful for battery-backed modules that sleep between wake events. The supply voltage range spans 1.8V to 3.3V, so the same BOM line can serve a 1.8V core rail or a 3.3V I/O rail without a separate level translator. ## Frequency stability and current draw Frequency stability is ±25 ppm over the full temperature and supply range — tight enough for most UART, SPI, and CAN clocking without external trimming. Maximum supply current is 7.2 mA at 27.6 MHz, keeping the thermal contribution low in a dense PCB layout.","metaTitle":"DSC1001CI2-027.6000B MEMS Oscillator – 27.6 MHz, AEC-Q100","metaDescription":"Microchip DSC1001CI2-027.6000B: 27.6 MHz XO, MEMS base, CMOS output, AEC-Q100, ±25 ppm, standby mode.
