1. DESCRIPTION
The S1D15710 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
microprocessor.
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 S1D15710 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.
Since both the S1D15710
have built-in analog temperature sensor circuits, systems
can be build that can maintain appropriate liquid crystal
contrast over a wide temperature range with
microcomputer control without requiring such parts as
thermostats.
The S1D15710 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 consumption and minimum component
configuration.
