2.2 Operating Voltage (VDD, VSS)
The core CPU and internal peripheral circuits operate with a voltage supplied between the VDD and VSS pins. The following operating voltage can be used:
VDD = 1.8 V to 3.6 V (VSS = GND)
Note: The S1C33L03 has 4 VDD pins and 10 VSS pins. Be sure to supply the operating voltage to all the pins. Do not open any of them.
The operating clock frequency range (OSC3) is 5 MHz to 50 MHz with this voltage.
