  2. Can H8SX operate with Vcc = 3.0 V?

    LVD enable of the Low Voltage Detection Control Register (LVDCR) of the LVD circuit is invalid at its initial value (LVDE = 0) so H8SX can operate at Vcc = 3.0 V. However, if the LVD circuit is enabled while Vcc = 3.0 V, Vdet is min value 3.0 V ...

  3. Is there any evaluation data with the resonator available?

    No. Since resonator matching is evaluated based on your board and the resonator manufacturer you will use, we do not provide any specific evaluation data. If you require evaluation data, please confer with your resonator manufacturer.
