What you see above is a master clock. It is the center of a system that can run an unlimited number of slave clocks, keeping them on-time thanks to its ability to synchronize with an atomic clock.

Many microcontrollers include timer circuits, but only a few include a battery-backed real-time clock (RTC). Yet many applications require an RTC, which you can easily add by using a 1-Wire network.

Operating at a 48-MHz clock speed, FTDI Chip’s FT51 microcontroller (MCU) features 48-MIPS processing capacity (one clock cycle per instruction). A hardwired USB hub function enables cascading of ...
