3.4.1 Oscillators

RL78 and MSPM0 devices have many types of clock sources including both internal and external for low system cost and low power consumption. Table 3-6 lists the different clock sources in RL78 and MSPM0 devices. Note that not all the devices have all types clock sources. For details, see the device-specific data sheet.

Table 3-6 Oscillator Comparison
Type RL78 MSPM0L MSPM0G MSPM0C MSPM0H
Internal oscillators fHOCO/fIH: internal high-speed oscillator up to 40MHz, which can source the PLL for 80MHz SYSOSC: internal oscillator from 4MHz to 32MHz SYSOSC: internal oscillator from 4MHz to 32MHz, which can source the PLL for 80MHz

SYSOSC: internal 24MHz and 32MHz oscillator

 SYSOSC : internal 32MHz oscillator
