SH3001
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%.
