[* Remark Solves]
*1. Though the wide range of operating voltages is guaranteed, a spike voltage change may affect the voltage
assurance during access from the MPU.
*2. In case of external power supply is applied.
*3. CS1B, CS2, RS, DB0 to DB7, E_RDB, RW_WRB, RESETB, C68, PS, INTRS, HPMB pins.
*4. DB0 to DB7, FR, FRS, CL pins.
*5. CS1B, CS2, RS, DB[7:0], E_RDB, RW_WRB, RESETB, C68, PS, INTRS, HPMB pins.
*6. Applies when the DB[7:0], FR, FRS and CL pins are in high impedance.
*7. Resistance value when
±
0.1[mA] is applied during the ON status of the output pin SEGn or COMn.
RON =
V / 0.1 [k
] (
V: voltage change when
±
0.1[mA] is applied in the ON status.)
*8. See table 21 for the relationship between oscillation frequency and frame frequency.
*9. On-chip reference voltage source of the voltage regulator circuit to adjust V
LCD
.
*10,11. Applies to the case where the on-chip oscillation circuit is used and no access is made from the MPU.
The current consumption, when the built-in power supply circuit is ON or OFF.
The current flowing through voltage regulation resistors (Ra and Rb) is not included.
It does not include the current of the LCD panel capacity, wiring capacity, etc.
