SPECIFICHE TECNICHE

Funzione dei Pin di Interfaccia

Pin No. Simbolo Level descrizione
1 /CS1 I The chip select signal
2 /RES I When RES is set to “L”, the setting are initialized.
3 A0 I 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.
4 /WR(R/W) I • 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.
5 /RD(E) I • 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.

24 VRS Power
Supply
This is the internal-output VREG power supply for the LCD power supply voltage
regulator.
25 V4 Power
Supply
This is a multi-level power supply for the liquid crystal drive.
26 V3
27 V2
28 V1
29 V0
30 VR I 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.
31 C86 I This is the MPU interface selection pin.
C86 = “H”: 6800 Series MPU interface.
C86 = “L”: 8080 Series MPU interface
32 P/S I 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
33 /HPM I This is the power control terminal for the power supply circuit for liquid crystal drive.
/HPM = “H”: Normal mode
/HPM = “L”: High power mode
34 IRS I 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
