MEMS resonator vs quartz — what changes on your BOM
The part ships blank (user must program), so you set the output frequency anywhere from 2 kHz to 80 MHz using Microchip's programming tools. One reel of blank devices can serve multiple BOM lines at different frequencies, reducing inventory SKUs.
Supply voltage and temperature grade — fit to your rail
Supply voltage spans 1.71 V to 3.63 V, covering 1.8 V, 2.5 V, and 3.3 V logic rails without a separate regulator. Current draw is 1.3 mA typical at max frequency, which is low enough for battery-powered modules.
Package and layout — 4-VFLGA footprint
Housed in a 4-VFLGA package measuring 1.60 mm x 1.20 mm with a seated height of 0.89 mm. The small footprint suits space-constrained PCBs in automotive ECUs or portable devices.
