What Clocks Do You Need?
MSP430 provides a wide range of clocking options. Before choosing and configuring the clocks,
though, you need to determine which clock features are most important for your system: Fast,
low-power, accurate, etc. At times, choosing these various options may force you to make
tradeoffs; hence, it’s important to for you consider which of these (or what group of them) are
most significant for your end-application.
What Clocks Do You Need?
Fast Clocks
CPU, Communications, Burst Processing
Low-power RTC, Remote, Battery, Energy Harvesting
Accurate Stable over ⁰/V, Communications, RTC, Sensors
Failsafe Robust–keeps system running in case of failure
Cheap … goes without saying …
… or some combination of these features?
