The supporting pins can reduce the influences from stresses on the
This is a ground pin. It also acts as a reference for the logic pins. It
must be connected to external ground
This is the most positive supply pin of the chip. They must be
connected to external source.
This pin is the input pin for the voltage output high level for COM
signals. A tantalum capacitor should be connected between this pin
and VSS.
This is analog ground pin. IT should be connected to VSS
externally
These pins are 8-bit bi-directional data bus to be connected to the
microprocessors data bus. When serial mode is selected, D1 will be
the serial data input SDIN and D0 will be the serial clock input
SCLK.
Unused pins must be connected to VSS except for D2 in serial
mode.
This pin is MCU interface input. When interfacing to a 68XX-
sseries microprocessor, this pin will be used as the Enable (E)
signal. Read/write operation is initiated when this pin is pulled high
and the CS# is pulled low.
When connecting to an 80XX-microprocessor, this pin receives the
Read (RD#) signal. Data read operation is initiated when this pin is
low and CS# is pulled low.
When serial mode is selected, this pin must be connected to VSS.
This pin is MCU interface input. When interfacing to a 68XX-series
microprocessor, this pin will be used as Read/Write (R/W#)
selection input. Pull this pin to “High” for read mode and pull it
“Low” for write mode.
When 80XX interface mode is selected, this pin will be the Write
(WR#) input. Data write operation is initiated when this pin is
pulled low and the CS# is pulled low.
When serial mode is selected, this pin must be connected to VSS.
These pins are MCU interface selection input. See the following
