Descripción

IRS

This terminal selects the resistors for the V0 voltage level adjustment.
IRS = “H”: Use the internal resistors
IRS = “L”: Do not use the internal resistors. The V0 voltage level is

regulated by an external resistive voltage divider attached to the VR terminal

/HPM

This is the power control terminal for the power supply circuit for liquid crystal drive.
/HPM = “H”: Normal mode
/HPM = “L”: High power mode (Default)

P/S

This is the parallel data input/serial data input switch terminal.
P/S = “H”: Parallel data input.
P/S = “L”: Serial data input.
The following applies depending on the P/S status:

P/S	Data/Command	Data	Read/Write	Serial Clock
"H"	A0	D0 to D7	/RD,/WR	X
"L"	A0	SI(D7)	Write only	SCL(D6)

When P/S = “L”, D0 to D5 fixed “H”.
/RD (E) and /WR (R/W) are fixed to either “H” or “L”.
With serial data input, It is impossible read data from RAM

C86

This is the MPU interface selection pin.
C86 = “H”: 6800 Series MPU interface.
C86 = “L”: 8080 Series MPU interface

Output voltage regulator terminal. Provides the voltage between VSS and V0 through a resistive voltage divider.
IRS = “L” : the V0 voltage regulator internal resistors are not used.
IRS = “H” : the V0 voltage regulator internal resistors are used.

V0~V4

Power supply

This is a multi-level power supply for the liquid crystal drive.

VRS

Power supply

This is the internal-output VREG power supply for the LCD power supply voltage regulator

CAP4+

DC/DC voltage converter.

CAP2-

DC/DC voltage converter. Connect a capacitor between this terminal and the CAP2P terminal.

CAP2+

DC/DC voltage converter. Connect a capacitor between this terminal and the CAP2N terminal.

CAP1+

DC/DC voltage converter. Connect a capacitor between this terminal and the CAP1N terminal.

CAP1-

DC/DC voltage converter. Connect a capacitor between this terminal and the CAP1P terminal.

CAP3+

DC/DC voltage converter. Connect a capacitor between this terminal and the CAP1N terminal.

CAP5+

DC/DC voltage converter.

VOUT

DC/DC voltage converter. Connect a capacitor between this terminal and vss or VDD

I/O

Data bus line

/RD(E)

• When connected to 8080 series MPU, this pin is treated as the “/RD” signal of the 8080 MPU and is LOW-active.
The data bus is in an output status when this signal is “L”.
• When connected to 6800 series MPU, this pin is treated as the “E” signal of the 6800 MPU and is HIGH-active.
This is the enable clock input terminal of the 6800 Series MPU.

/WR(R/W)

• When connected to 8080 series MPU, this pin is treated as the “/WR” signal of the 8080 MPU and is LOW-active.
The signals on the data bus are latched at the rising edge of the /WR signal.
• When connected to 6800 series MPU, this pin is treated as the “R/W” signal of the 6800 MPU and decides the access type :
When R/W = “H”: Read.
When R/W = “L”: Write.

This is connect to the least significant bit of the normal MPU address bus, and it determines whether the data bits are data or command.
A0 = “H”: Indicates that D0 to D7 are display data.
A0 = “L”: Indicates that D0 to D7 are control data.

/RES

When RES is set to “L”, the setting are initialized.

/CS1

This is the chip select signal.
