SH3003

Overview
POWER MANAGEMENT Description Three components make a complete system: any microcontroller, the SH3003, and a bypass capacitor.
This low-cost system would consume very little power and have clock-frequency accuracy of ± 0.
5%.
A fourth component, a 32.
768kHz crystal, raises the clock frequency accuracy to ± 0.
0256% (± 256 ppm).
The SH3003 can operate completely stand-alone, or under control of the microcontroller.
A single-wire interface handles both bi-directional communications and the interrupt/wake-up signal from the SH3003.
The SH3003 stores all configuration, calibration, parameters, and status information in a 36-byte bank of control registers.
On reset, most of these are reloaded with d...
