说明

PSB

PSB selects the interface type: Serial or Parallel.

C86

C86 selects the microprocessor type in parallel interface mode.

PSB	C86	Selected Interface
“H”	“H”	Parallel 6800 Series MPU Interface
“H”	“L”	Parallel 8080 Series MPU Interface
“L”	“X”	Serial 4-Line SPI Interface

Please refer to “APPLICATION NOTES” and “Microprocessor Interface”(Section 6) for detailed connection of the selected interface.

Power

VG is the LCD driving voltage for segment circuits.

XV0

Power

XV0 is the LCD driving voltage for common circuits at positive frame.

Power

V0 is the LCD driving voltage for common circuits at negative frame.

VSS

Power

This is a 0V terminal connected to the system GND.

VDD

Power

Shared with the MPU power supply terminal VDD. ( 3.3 V )

D7-D0

I/O

When using 8-bit parallel interface: (6800 or 8080 mode)
8-bit bi-directional data bus. Connect to the data bus of 8-bit microprocessor.
When CSB is non-active (CSB=“H”), D[7:0] pins are high impedance.

When using serial interface: 4-LINE
D7=SDA : Serial data input.
D6=SCL : Serial clock input.
D[5:0] are not used and should connect to “H” by VDD1 or VDDH.
When CSB is non-active (CSB=“H”), D[7:0] pins are high impedance.

ERD

Read/Write execution control pin. When PSB is “H”,

C86	MPU Type	ERD	Descriptiion
H	6800 series	E	Read/Write control input pin. R/W="H":When E is "H",D[7:0] are in output mode. R/W="L":Signais on D[7:0] are latched at the failing edge of E signal.
L	8080 series	/RD	Read enble input pin. When /RD is "L",Ｄ[7:0] are in output mode.

ERD is not used in serial interface and should fix to “H” by VDD1 or VDDH.

RWR

Read/Write execution control pin. When PSB is “H”,

C86	MPU Type	RWR	Descriptiion
H	6800 series	R/W	Read/Write control input pin. R/W="H":read R/W="L":write
L	8080 series	/WR	Write enble input pin. Signals on D[7:0] will be latched at the rising edge of /WR signal.

RWR is not used in serial interface and should fix to “H” by VDD1 or VDDH.

It determines whether the access is related to data or command.
A0=“H” : Indicates that signals on D[7:0] are display data.
A0=“L” : Indicates that signals on D[7:0] are command.

RSTB

Hardware reset input pin. When RSTB is “L”, internal initialization is executed and the internal registers will be initialized.

CSB

Chip select input pin. Interface access is enabled when CSB is “L”.When CSB is non-active (CSB=“H”), D[7:0] pins are high impedance.
