LCD Controller-Driver
S-4561A
The S-4561A is a 17-common x 60-segment output character LCD
controller-driver with built-in serial and parallel interfaces. The S-4561A
incorporates CGROM, making character display possible. Independently
of the CPU, display on the LCD panel is executed via the internal
oscillating circuit or clock input. The S-4561A has a wide variety of
command instructions which minimize the load of the CPU. It also
features a wide voltage range, low power consumption, and it is provided
with a power save function, making the S-4561A a suitable display
device for applications in portable electronics.
