Why a blank-programmable MEMS oscillator for automotive
The DSC6001MA3B-PROG ships without a frequency set — it is a blank MEMS resonator that the buyer programs to any frequency between 2 kHz and 80 MHz. This avoids stocking dozens of fixed-frequency quartz cans for different BOM lines; one part number covers the range, and the frequency is set at programming. The MEMS base resonator handles the shock and vibration profile of an engine bay better than a quartz crystal — no start-up reliability surprises after a pothole. Total frequency stability of ±20 ppm covers the timing budget for CAN, LIN, and most microcontroller clock inputs without external trimming. The 1.71V to 3.63V supply range lets it run from a 1.8V or 3.3V rail directly — no extra LDO.
Programming workflow and supply voltage flexibility
The blank part is programmed by the buyer using Microchip's field-programmable oscillator programming kit (not included). The 4-VFLGA package — 2.00 mm x 1.60 mm footprint — requires a standard LGA socket or reflow programming fixture; the programming current is drawn from the 1.71V–3.63V supply pin.
No pin-compatible second source is documented, but the DSC60XXB series shares the same footprint and programming flow, so a different frequency variant from the same series can be substituted without a board spin.
