V0
D0-D15, CSB, RS, M/S, M86, RDB, WRB, CK, CKS, P/S, RESB, & TEST pins.
D0 ~ D15 pins
CLK pins
CSB, RS, M/S, M86, RDB, WRB, CK, CKS, P/S, RESB, & TEST pins
Applied when D0 ~ D15 are in the state of high impedance.
SEGA0 ~ SEGA97, SEGB0 ~ SEGB97, SEGC0 ~ SEGC97, COM0 ~ COM67 pin
resistance when 0.5V is applied between each output pin and to each power supply (V0,
V1, V2, V3, V4) and when applied 1/9 bias.
VDD pin. VDD pin current is without load when the original oscillating clock is stopped
and when CSB=VDD.
Oscillator frequency, when using the built-in oscillating circuit (65k-color mode)
Oscillator frequency, when using the built-in oscillating circuit (4k-color mode)
Oscillator frequency, when using the built-in oscillating circuit (256-color mode)
VOUT pin. This pin applies when the following conditions are met: The built-in oscillator
circuit is used; the built-in power supply is used; the voltage (boosted 6 times) is used;
VEE = 2.4 ~ 3.3; and the electronic control is preset (with code “1 1 1 1 1 1 1”).
Measuring conditions: bias=1/4~1/9; 1/68 duty; LCD driver pin is without load; RL=500
K (between VOUT and VSS); C1=C2=1.0µF; C3=0.1µF; DCON=AMPON=”1”;
BF=”11”.
VOUT pin. This pin applies when the following conditions are met: The built-in oscillator
circuit and built-in power supply are used; the voltage (boosted 5 times) is used;
VEE = 2.4 ~ 3.3; and the electronic control is preset (with code “1 1 1 1 1 1 1”).
Measuring conditions: bias=1/4~1/9; 1/68 duty; LCD driver pin is without load; RL=500
K (between VOUT and VSS); C1=C2=1.0µF; C3=0.1µF; DCON=AMPON=”1”;
BF=”11”.
VOUT pin. This pin applies when the following conditions are met: The built-in oscillator
circuit and built-in power supply are used; the voltage (boosted 4 times) is used;
VEE = 2.4 ~ 3.3; and the electronic control is preset (with code “1 1 1 1 1 1 1”).
Measuring conditions: bias=1/4~1/9; 1/68 duty; without load; RL=500 K (between
VOUT and VSS); C1=C2=1.0µF; C3=0.1µF; DCON=AMPON=”1,” BF=”11”.
VOUT pin. This pin applies when the following conditions are met: The built-in oscillator
circuit and built-in power supply are used; the voltage (boosted 3 times) is used;
VEE = 2.4 ~ 3.3; and the electronic control is preset (with code “1 1 1 1 1 1 1”).
Measuring conditions: bias=1/4~1/9; 1/68 duty; LCD driver pin is without load; RL=500
K (between VOUT and VSS); C1=C2=1.0µF; C3=0.1µF; DCON=AMPON=”1”;
