CHAPTER 9: ELECTRICAL CHARACTERISTICS
VC1/VC2 output voltage-temperature characteristic (Typ. value)
OSC1: 32.768kHz crystal oscillation, VDD = 3V, VSS = 0V, no panel load, CGX = 25pF, CGC = CDC = 30pF, C1–C8 = 0.2µF
The LCD drive voltage output from the internal LCD drive power circuit varies depending on temperature.
This graph is provided only for reference and the characteristic varies according to mounting conditions,
parts used and the measurement environment.
