The operating voltage range applies if an external power supply is used.
*3 A0, D0 - D5, D6, D7 (SI), RD (E), WR (R/W), CS1, CS2, FR, M/S, C86, P/S and DOF pins
*4 CL, SCL (D6) and RES pins
*5 D0 - D5, D6, D7 (SI), FR, FRS, DYO, DOF and CL pins
*6 A0, RD (E), WR (R/W), CS1, CS2, M/S, RES, C86 and P/S pins
*7 Applies when the D0 - D7, FR, CL, DYO and DOF pins are in high impedance,
*8 Resistance value when 0.1 V is applied between the output pin SEGn or COMn and each power supply pin (V1, V2, V3, V4).
This is specified in the operating voltage (2) range.
R ON = 0.1 V/∆I (∆I: Current flowing when 0.1 V is applied in the ON status.)
*9 For the relationship between oscillation frequency and frame frequency, refer to Fig. 9.

within the voltage follower operating voltage range.
*12, *13 Current that each IC unit consumes. It does not include the current of the LCD panel capacity, wiring capacity, etc.
This is current consumption under the conditions of display data = checker, display ON, S1D15300 = 1/33 duty (1/6 Bias), and S1D15301
and S1D15302 = 1/65 duty. (1/8 Bias)
*12 Applies to the case where the on-chip oscillator circuit is used and no access is made from the microprocessor.
*13 Applies to the case where the on-chip oscillator circuit and the on-chip power circuit are used and no access is made from the
microprocessor.
The current flowing through voltage regulation resistors (R1, R2 and R3) is not included.
The current consumption, when the on-chip voltage booster is used, is for the power supply V
DD
.
• Relationship between oscillation frequency and frame frequency
The relationship between oscillation frequency f
OSC
and LCD frame frequency, f
F
can be obtained by the following expression.
(f
