Automotive-grade MEMS oscillator with field programmability
Its key differentiator for automotive and industrial designs is the AEC-Q100 qualification — this is a qualified part, not a 'capable' one — with a -40 to 125 °C operating temperature that covers under-hood and engine-bay thermal profiles. The device ships as a blank (user must program) via Microchip's programming tools, allowing the BOM to source a single order code for multiple frequencies — a practical inventory consolidation move for high-mix production lines.
Supply rail and package constraints for board layout
Supply voltage spans 1.71 V to 3.63 V, covering standard 1.8 V, 2.5 V, and 3.3 V logic rails without an external regulator. The 4-VFLGA package measures 1.60 mm x 1.20 mm with a seated height of 0.89 mm — a compact footprint that suits space-constrained ECU and sensor module layouts. The total frequency stability is ±20 ppm, which includes temperature, supply, and aging effects — sufficient for most CAN, LIN, and Ethernet clocking applications.
