The S-4544A is a 17- or 33-common, 128-segment output graphic (bit
map) LCD controller-driver with built-in 8-bit and serial interfaces. The
internal 65 x 128 bit display data RAM can directly access the 8-bit and
the serial data bus, making the display of both graphics and characters
possible. It displays the data independently of the CPU through the built-
in oscillating circuit or clock input. It has a wide variety of command
instructions which minimize the load onto the CPU. It also features a
wide voltage range and the low power consumption during display,
making the S-4544A a suitable display for system applications in
portable electronics.
