SH3000 MicroBuddy™ www.DataSheet4U.com Low-Power Programmable Multifunction Support IC for Microcontrollers SYSTEM MANAGEMENT Description The programmable SH3000 MicroBuddy™ (µBuddy™) provides all mandatory microcontroller support functions: ♦ CPU Supervisor ♦ Clock Management System ♦ Real Time Support ♦ Auxiliary functions Three components make a complete system: any microcontroller, the SH3000, 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 watch crystal, raises the clock frequency accuracy to ± 0.0256% (± 256 ppm). The SH3000 can operate completely stand-alone, or under control of the microcontroller.
