1. DESCRIPTION
The S1D15722 series is a MLS drive system dot matrix LCD driver that can be directly connected to the
microcomputer bus. An 8-bit parallel or serial display data sent from the microcomputer is stored in the
built-in display data RAM and LCD drive signal is generated independently of the microcomputer. (Required
external LCD bias voltages input.)
The S1D15722 series provides both FRM 4-grayscale display and binary display. With display data RAM
224

2 bits incorporated, for 4-grayscale display, 2 bits of built-in RAM correspond to 1 dot of pixel, and
for binary display, 1 bit of the built-in RAM corresponds to 1 dot of pixel.
The S1D15722 series contains 184 circuits of common output and 224 circuits of segment output. This
allows display of a maximum of 224
×
184 dots per chip.
Read/write operation from microcomputer to display data RAM does not require external operation clock.
