Clock Timing

Table 32.19 Operating Frequency Value (High-Speed Operating Mode)
Conditions: VCC = 2.7 V to 5.5 V, AVCC0 = VCC to 5.5 V, VSS = AVSS0 = 0 V, T
Maximum operating System clock (ICLK)

frequency*
FlashIF clock (FCLK)*
Peripheral module clock (PCLKB)
Peripheral module clock (PCLKD)*
Note 1. The lower-limit frequency of FCLK is 1 MHz during programming or erasing of the flash memory. When using FCLK at below 4
MHz, the frequency can be set to 1 MHz, 2 MHz, or 3 MHz. A non-integer frequency such as 1.5 MHz cannot be set.
Note 2. The frequency accuracy of FCLK should be ±3.5%.
Note 3. The minimum frequency of PCLKD is 1 MHz when the A/D converter is to be used.
Note 4. The maximum operating frequencies do not take errors in the HOCO frequency and jitters in the PLL signal. Refer to Table
32.21, Clock Timing.
