Notes to the DC characteristics
1. The maximum possible VLCD voltage that may be generated is dependent on voltage, temperature and (display) load.
2. Internal clock
3. Power-down mode. During power down all static currents are switched off.
4. If external VLCDIN, the display load current is not transmitted to IDD
.
5. VOUT external voltage applied to VLCDIN pin; VLCDIN disconnected from VLCDOUT (no connect)

fluctuations to the voltage while the MPU is being accessed.

*5 Applies when the D0 to D5, D6 (SI), D7 (SCL) terminals are in a high impedance state.
*6 These are the resistance values for when a 0.1 V voltage is applied between the output terminal SEGn or COMn and the
various power supply terminals (V1, V2, V3, and V4). These are specified for the operating voltage range.
RON = 0.1 V /∆I (Where ∆I is the current that flows when 0.1 V is applied while the power supply is ON.)
*7 The relationship between the oscillator frequency and the frame rate frequency.
*8,9It indicates the current consumed on ICs alone when the internal oscillator circuit and display are turned on.
