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)

*1 While a broad range of operating voltages is guaranteed, performance cannot be guaranteed if there are sudden

fluctuations to the voltage while the MPU is being accessed.

*2 The A0, D0 to D5, D6 (SI), D7 (SCL), /RD (E), /WR ,/(R/W), CSB, IMS, OSC, P/S, /DOF, RESB ,and MODE terminals.

*3 The D0 to D7, and OSC terminals.

*4 The A0,/RD (E), /WR ,/(R/W), CSB, IMS, OSC, P/S, /DOF, RESB ,and MODE terminals.

*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 /

ΔI (Where ΔI 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.
