ST7565S
Reference Circuit Examples
1. When used all of the step-up circuit, voltage regulating circuit and V/F circuit
(1) When the voltage regulator internal resistor is used.
(Example where VSS2 = VSS, with 4x step-up)
(2) When the voltage regulator internal resistor is not used.
(Example where VSS2 = VSS, with 4x step-up)
