Dot Matrix LCD Driver
S-4543A

Seiko Instruments Inc.
OPERATION
1.Power-on and off
1.1 Power-on
After power-on, set the default parameters through command input. Input the display off command immediately
after the CPU starts. Set other parameters in order until the display starts. The C3/2X pin must be connected to
V
DD
or V
SS
for use. The recommended procedures after power-on, are as follows:
1. Display ON/OFF
D0: 0
Display OFF
2. Full display ON/OFF
D0: 0
Full display OFF (start of oscilation)
3. End command input
4. ADC selection
5. Display start line
6. Page address "0000"
7. Column address "0000000"
8. Write display data *
9. Display ON
D0: 1
Display ON (start of display)
* After power-on, write display data to all addresses of the display RAM before setting the display to ON because
display RAM is not defined at start up.
1.2 Power-off
Power-off after setting display OFF through a CPU command. The recommended procedures at power-off are
as follows:
1. Display ON/OFF
D0: 0
Display OFF
Note:
After power-on, the parameters except display data RAM are initialized by the operation of the
internal reset circuit. The reset circuit operates at the positive edge of the power-on from ground
voltage level. The operation of the reset circuit can not be guaranteed when the power does not rise
from ground voltage level because of residual voltage from a momentary power failure or continuous
power-on operations.
2.MPU Interface Select
In the S-4543A series, the 8-bit interface or serial interface can be selected.

Note: The displayed data write instruction and displayed data read instruction cannot be executed with E1 and E2
active at the same time.
