Connects to a +5-V power supply. Used in common with the MPU power terminal.
A 0-V terminal connected to the system GND.
Multi-level power supply terminals for driving the LCD panel. Through divisions by
resistors or impedance conversion with an operational amplifier, they apply a voltage
determined by the LCD cells.Electric potential is determined depending on VDD. The
following relationship must be observed.
V
Three-state I/O terminals
They comprise an 8-bit bi-directional data bus, and connected to an 8- or a 16-bit
standard MPU data bus.
Input terminal
Typically, the least significant bit of an MPU address bus is connected to discriminate
between data and commands.
0: Represents that D
1: Represents that D
Input
By setting RES to “
are reset when a RES signal edge is detected. After initialization, the type of an interface
to the 68/80 MPUs is selected depending on the input level.
Input activated at the LOW level
A terminal for chip selection signals. Typically, signals that result from decoding of
address bus signals are input.
<When series 68 MPU is connected>
Input activated at the HIGH level
An enable clock input terminal for the MPU.
<When series 80 MPU is connected>
Input activated at the LOW level
A terminal for RD signal from the MPU. The data bus on the S1D15400 outputs signals
while the RD signal is at the LOW level.
<When series 68 MPU is connected>
Input
An input terminal for read/write control signals.
R/W = HIGH: Read
R/W = LOW: Write
<When series 80 MPU is connected>
Input activated at the LOW level
A terminal for WR signal from the MPU. The signals on the data bus are fetched at a
rising edge of the WR signal.
HIGH: Interface to series 68 MPU is selected.
LOW : Interface to series 80 MPU is selected.
