SED157A Series
I
OVERVIEW
The SED157A Series is a single-chip dot matrix liquid crystal display driver that can be connected directly to a
microprocessor bus. Eight-bit parallel or serial display data transmitted from the microprocessor is stored in the
internal display data RAM, and the chip generates liquid crystal drive signals, independently of the micropro-
cessor.
It has a on-chip 65
×
256-bit display data RAM, and there is a one-to-one correspondence between the dot pixel
on the liquid crystal panel pixels and internal RAM bit. This feature ensures implementation of highly free
display.
The SED157A Series incorporate 65 common output circuits and 224 segment output circuits. A single chip
can drive a 65
×
224 dot display (capable of displaying 14 columns
×
4 rows with 16
×
16-dot kanji font).
Further, display capacity can be extended by designing two chips in a master/display configuration.
The SED157A Series can read and write RAM data with the minimum current consumption because it does not
require any external operation clock. Also it incorporates a LCD power supply featuring a very low current
consumption, a LCD drive power voltage regulator resistor and a display clock CR oscillator circuit. This allows
the display system of a high-performance for handy equipment to be realized at the minimum power consump-
tion and minimum component configuration.
