This programmable MEMS oscillator is factory set to 512 Hz and belongs to a family covering 1 Hz to 32.768 kHz. This variant is rated for -40 °C to +85 °C operation with ±100 ppm frequency stability and uses a 2.0 x 1.2 mm package. It operates from 1.2 V to 3.63 V and draws 0.9 µA typical core current at 1.8 V with no load, with additional output-stage current that scales with output swing. The device eliminates external load capacitors, supports NanoDrive reduced-swing output options, and specifies 35 ns RMS period jitter.
