S1D15300 Series
5–6 EPSON Rev.1.4
Name I/O Description Number of pins
WR I • Write enable input. When interfacing to an 8080-series microprocessor, 1
(R/W) WR is active LOW.
• When interfacing to an 6800-series microprocessor,
it will be read mode when R/W is HIGH and it will be write mode when
R/W is LOW.
R/W = “1”:Read
R/W = “0”:Write
C86 I Microprocessor interface select terminal. 1
C86 = HIGH: 6800 series microprocessor interface
C86 = LOW: 8080 series microprocessor interface
P/S I Serial data input/parallel data input select pin. 1
* In serial mode, no data can be read from RAM.
When P/S = LOW, D0 to D5 are HZ and RD and WR must be fixed HIGH
or LOW.

LCD Driver Outputs
Name I/O Description Number of pins
M/S I S1D15300 series master/slave mode select input. When a necessary 1
signal is output to the LCD, the master operation is synchronized with
the LCD system, while when a necessary signal is input to the LCD,
the slave operation is synchronized with the LCD system.
M/S = HIGH: Master operation
M/S = LOW : Slave operation
The folLOWing is provided depending on the M/S status.
CL I/O Display clock input/output. When the S1D15300 series selects master/ 1
slave mode, each CL pin is connected. When it is used in
combination with the common driver, this input/output is connected to
common driver YSCL pin.
M/S = HIGH: Output
M/S = LOW: Input
FR I/O LCD AC signal input/output. When the S1D15300 series selects master/ 1
slave mode, each FR pin is connected.
When the S1D15300 series selects master mode this input/output is
connected to the common driver FR pin.
M/S = HIGH: Output
M/S = LOW: Input
DYO I/O Common drive signal output. This output is enabled for only at master 1
operation and connects to the common driver DIO pin. It becomes HZ
at slave operation.
VS1 O Test pin. Don’t connect. 1
DOF I/O LCD blanking control input/output. When the S1D15300 series selects 1
master/slave mode, the respective DOF pin is connected. When it
is used in combination with the common driver (S1D16305), this output/
input is connected to the common driver DOFF pin.
M/S = HIGH: Output
M/S = LOW: Input
FRS O Static drive output. 1
This is enabled only at master operation and used together with the FR
pin. This output becomes HZ at slave operation.
