Specification
Power supply for signals interfacing with
MPU or LCDC. Supply through the system.
Power supply for CS*, RS, WR*/SCL, RD*,
DB17-2, DB1/SDO, DB0/SDI, VSYNC,
HSYNC, ENABLE, PD17-0.
Connect on the FPC when using at the
same electric potential with Vcc1.
Power supply for signals interfacing with a
gate driver/power supply IC and a deep
standby mode control circuit that halts the
logic regulator.
Supply with the same electric potential with
Vcc of HD66783 or HD667P21 though the
system.
Power supply for FLM1, FLM2,
CL11/SFTCLK11, CL12/SFTCLK12,

Connect on the FPC when using at the
same potential with IOVcc.
Supply through the system.
Connect on the FPC when using at the
same electric potential with Vci of HD66783
or HD667P21.
Generated from the internal logic regulator.
Supply through the system is not required.
GND for the internal logic circuit. Connect to
GND on the FPC.
GND for the internal GRAM. Connect to
GND on the FPC.
GND for the I/O side and analogue circuits
other than logic circuits and the internal
GRAM, which operate with VDD voltage.
Connect to GND on the FPC.
