Microchip lists the DSC6001HI2A-032.0000 as Obsolete.
Automotive-grade MEMS clock source
This is a MEMS-based XO (Standard) oscillator delivering a 32 MHz CMOS output. The MEMS resonator provides inherent shock and vibration tolerance compared to quartz, and the part carries AEC-Q100 qualification, meaning it has passed the automotive-grade reliability stress tests (temperature cycling, ESD, latch-up) required for under-hood or cabin deployment.
Operates from 1.71 V to 3.63 V, covering common 1.8 V, 2.5 V, and 3.3 V logic rails without an external regulator. Frequency stability is ±25 ppm across the full temperature and supply range.
Package and standby function
Housed in a 4-SMD no-lead package measuring 1.60 mm x 1.20 mm — a compact footprint for space-constrained PCBs. The Standby (Power Down) function allows the oscillator to be disabled, reducing current draw to near zero when the clock is not needed.
