  • Page 16: Power Supply And Initial Reset

    The S1C6P366 operating power voltage is as follows: 2.7 V to 5.5 V The S1C6P366 operates by applying a single power supply within the above range between V and V . The S1C6P366 itself generates the voltage necessary for all the internal circuits by the built-in power supply circuits shown in Table 2.1.1.

  • Page 17: Voltage For Oscillation Circuit And Internal Circuits

    Since the power supply voltage of the S1C6P366 is 2.7 V or more, this switching is not necessary and the software control does not affect the operating mode. However, when using the S1C6P366 as a development tool for the S1C63358/63158, the operating mode control routine must be implemented according to the model.
