18.5.3.4 Clock Domains

The device has these synchronous clock domains:

  • CPU synchronous clock domain (CPU Clock Domain). Frequency is fCPU.
  • Low Power synchronous clock domain (LP Clock Domain). Frequency is fLP.
  • Backup synchronous clock domain. (BUP Clock Domain). Frequency is fBUP.

See the references for the clock domain partitioning. Refer to the Maximum Clock Frequencies in the Electrical Characterization section for maximum frequencies in each performance level.
