Product details

AEC-Q100 qualified MEMS oscillator for automotive clocks

The MEMS resonator eliminates quartz crystal aging drift and startup time, which simplifies timing margin in CAN, LIN, or Ethernet PHY clock trees.

Standby mode and supply current profile

When the standby (power-down) function is asserted, the oscillator draws only 15 µA max — low enough to keep an always-powered ECU module in sleep without draining the battery. The supply voltage range of 1.8V to 3.3V covers common 1.8V and 3.3V logic rails without an external regulator.

Housed in a 4-SMD, No Lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm.

Product status is Active — Microchip continues to manufacture and support this order code.

Frequently asked questions

Is the DSC1001BI5-012.0000 AEC-Q100 qualified?

Yes, the ratings field explicitly lists AEC-Q100. This qualification covers the automotive-grade reliability stress tests — temperature cycling, ESD, latch-up — making it suitable for under-hood and cabin electronic modules.

Can I use the DSC1001BI5-012.0000 to replace a quartz oscillator in my design?

Yes, the MEMS resonator in the DSC1001BI5-012.0000 is a drop-in replacement for a standard 12 MHz quartz oscillator in a 4-SMD, No Lead package. The MEMS version offers faster startup, no aging drift, and better shock/vibration tolerance. Confirm that your board's supply voltage (1.8V to 3.3V) and output load (CMOS) match the oscillator's ratings.

How does the standby mode work on the DSC1001BI5-012.0000?

The standby (power-down) function disables the oscillator output and reduces current draw to 15 µA max. Asserting the standby pin stops the clock; de-asserting it restarts the output within the specified startup time. This is useful for battery-powered or always-on modules that need a low-power sleep state.
