AEC-Q100 qualification confirms it passed the automotive-grade stress tests: temperature cycling, ESD, latch-up, and extended life at -40°C to 85°C. This is the temperature band for cabin and most under-hood electronics — a body controller or infotainment head unit sees this range without margin issues. The 1.7V to 3.6V supply range lets it run directly off a 1.8V, 2.5V, or 3.3V rail without an extra LDO — useful when the MCU or SoC has multiple voltage domains and you want a single oscillator to feed the core clock input. ## Frequency stability and power budget for the BOM ±25 ppm frequency stability is tight enough for CAN, LIN, and most 100BASE-T1 Ethernet PHYs, but not for precision GPS or RF references that need ±10 ppm or better — budget a TCXO if your application requires sub-20 ppm over the full temperature range. Max supply current is 7.4 mA, and the standby (power-down) function drops it to 15 µA max — the disable pin lets the system power down the oscillator when the MCU sleeps, saving battery in key-off automotive modules. The DSC1003 series is Microchip's baseline MEMS oscillator family, and this order code is a standard catalog variant — no special program or allocation constraints expected.","metaTitle":"DSC1003AI2-040.0000 MEMS Oscillator 40 MHz AEC-Q100","metaDescription":"Microchip DSC1003AI2-040.0000: XO (Standard) 40 MHz CMOS MEMS oscillator, AEC-Q100, ±25 ppm, 1.7V-3.6V, -40°C to 85°C, 4-SMD.
