NOTES :

1. Applied when D7 to D0, LP, FLM, and M are in the high

impedance state.

2. Resistance when 0.5 V is applied between each output

pin and each power supply (V0, V1, V2, V3, V4). Applied

when power is supplied at power bias ratio of 1/9 in the

external power supply mode.

3. Current at the VDD pin when the master clock stops, the

chip is not selected (CSB = VDD), and no load is used.

All circuits stop.

4. Sleep mode supply current.

Stop internal oscillation clock, using external EXA signal.

Without using booster circuits. Graphic and segment

displays OFF. Icon display ON. No load.

5. Applied when no access is made by the MPU when the

internal oscillation circuit (RF = 680 k$) and power

supply circuit (PMODE = "L") are used. The electronic

volume is preset (the code is "1 1 1 1"). The display is

OFF and the LCD drive pin is not loaded.

Measuring conditions : VDD = VEE, VR1 = VR2, C1 = C2 =

1 µF, R1 + R2 + R3 = 4 M$.

6. Active mode supply current.

Using internal oscillation clock.

Writing at fCYC the graphic display data which are

reversed every one bit. No load.

7. Oscillation frequency when connecting a feedback

resistor (RF) of 680 k$ between OSCI and OSCO.
