Overview
SH3001 MicroBuddy™ www.
DataSheet4U.
com Real-Time Clock and Clock Management Support IC for Microcontrollers SYSTEM MANAGEMENT Description The programmable SH3001 MicroBuddy™ (µBuddy™) provides mandatory microcontroller support functions: ♦ Clock Management System ♦ Real-Time Support ♦ Auxiliary functions Three components make a complete system: any microcontroller, the SH3001, 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.
768 kHz crystal, raises the clock frequency accuracy to ± 0.
0256% (± 256 ppm).
The SH3001 can operate completely stand-alone, or under control of the microcontroller.
A single-wire interface handles bi-directional communications.
The SH3001 stores all configuration, calibration, parameters, and status information in a 36-byte bank of control registers.
On reset, most of these are reloaded with defaults from the factory-set nonvolatile memory.
The microcontroller can c...
