Overview of SYSIOP Maximum Frequency
The following tables describe the maximum operating frequencies of the System and I/O Processor and the
SYSTEM Bus – the main function blocks of the SYSIOP. Each has a different maximum operating frequency
depending on the supported XOSC frequency and the SYSPLL oscillating frequency. The SYS SRAM within the
SYSIOP has the same operating frequency as the System and I/O Processor. The element circuits (BackUp SRAM,
DMAC, Crypto…) directly connected to the SYSTEM Bus or via a synchronous bridge basically have the same
maximum frequencies as the SYSTEM Bus.
For the maximum operating frequencies of external communication interfaces, refer to each respective Part. For
the XOSC and SYSPLL frequency settings, refer to Section 3.5.
