Interface Pin Function

Pin No. Symbol Level Description
1 P/S I This is the parallel data input/serial data input switch terminal.
2 C86 I This is the MPU interface switch terminal.
3 VR I Output voltage regulator terminal. Provides the voltage between VSS and V0 through a resistive voltage divider.
4~8 V0~V4 Power supply This is a multi-level power supply for the liquid crystal drive.
9 CAP2N O DC/DC voltage converter. Connect a capacitor between this terminal and the CAP2P terminal.
10 CAP2P O DC/DC voltage converter. Connect a capacitor between this terminal and the CAP2N terminal.
11 CAP1P O DC/DC voltage converter. Connect a capacitor between this terminal and the CAP1N terminal.
12 CAP1N O DC/DC voltage converter. Connect a capacitor between this terminal and the CAP1P terminal.
13 CAP3P O DC/DC voltage converter. Connect a capacitor between this terminal and the CAP1N terminal.
14 VOUT O DC/DC voltage converter. Connect a capacitor between this terminal and vss or VDD
15 VSS Power supply Ground
16 VDD Power supply Power supply
17~24 D7~D0 I/O This is an 8-bit bi-directional data bus that connects to an 8-bit or 16-bit standard MPU data bus.
25 /RD(E) I The data bus is in output status when this signal is “L”
26 /WR(R/W) I The data bus are latched at the rising edge of the WR signal
27 A0 I This is connect to the least significant bit of the Norman MPU address bus, and it determines whether the data bits are data or a command.
28 /RES I When RES is set to “L”, the setting are initialized.
29 /CS1 I This is the chip select signal.
