MEMS oscillator with AEC-Q100 – what it buys you
The DSC1001AE2-008.0000T is a MEMS-based XO (Standard) from Microchip's DSC1001 series, outputting 8 MHz CMOS from a 1.8V–3.3V supply. Its AEC-Q100 qualification means it passed the full automotive stress suite – temperature cycling, ESD, latch-up – so it can sit on an ECU board that sees vibration and thermal shock without the frequency wander a quartz crystal might show after a few thousand thermal cycles. The MEMS resonator is inherently more shock-tolerant than a quartz blank – no mechanical fracture risk under 50,000 g impact.
Active production – sourcing posture
It is a current production part from Microchip Technology, available through independent distribution. Pricing and stock are confirmed at RFQ against your BOM quantity; no minimum order threshold beyond the reel increment. The 4-SMD, No Lead Exposed Pad package measures 7.00mm x 5.00mm with a seated height of 0.90mm.
Standby function and supply current
A Standby (Power Down) function pulls the output to high-impedance and drops supply current to 15 µA max – useful for battery-backed RTC or wake-up timer circuits where the oscillator can be gated off between sampling intervals. Active supply current is 6.3 mA max at 8 MHz, which is typical for a MEMS oscillator at this frequency.
