製品仕様

ピン功能定義

Pin No. 記号 Level 説明
1 /CS1B I This is 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.

6~13 D0~D7 I/O Data bus line
14 VDD Power supply Power supply
15 VSS Power supply Ground
16 VOUT O DC/DC voltage converter. Connect a capacitor between this terminal and vss or VDD
17 CAP3P O DC/DC voltage converter. Connect a capacitor between this terminal and the CAP1N terminal.
18 CAP1N O DC/DC voltage converter. Connect a capacitor between this terminal and the CAP1P terminal.
19 CAP1P O DC/DC voltage converter. Connect a capacitor between this terminal and the CAP1N terminal.
20 CAP2P O DC/DC voltage converter. Connect a capacitor between this terminal and the CAP2N terminal.
21 CAP2N O DC/DC voltage converter. Connect a capacitor between this terminal and the CAP2P terminal.
22~26 V4~V0 Power supply This is a multi-level power supply for the liquid crystal drive.
27 VR I Output voltage regulator terminal. Provides the voltage between VSS and V0 through a resistive voltage divider.
28 C86 I This is the MPU interface selection pin.
C86 = “H”: 6800 Series MPU interface.
C86 = “L”: 8080 Series MPU interface
29 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
30 NC - No connection.
