SOLOMON
SYSTECH LIMITED ANNOUNCES A NEW SERIES OF
SINGLE
CHIP SEGMENT & COMMON LCD DRIVER / CONTROLLER
CHIPS
FOR
PORTABLE TELECOMMUNICATIONS AND CONSUMER APPLICATIONS
A New
Series That Cover Full Range 32mux to 64mux LCD Display
Hong
Kong, Nov 3, 1999 - Solomon Systech Limited today announced
a series of LCD drivers / controllers, part number SSD181X,
for portable telecommunications and consumer applications.
The LCD driver / controller chips were designed and
developed by the Solomon Systech development team located in
Hong Kong, which was formerly a professional team in
Motorola Semiconductor Products Sector. The series of LCD
drivers cover from 32 mux to 64 mux display with industry
standard interface and command set, tailor made for
telecommunication products such as cellular phones, pagers,
PHS and other portable consumer products.
The
SSD181X series, capable of driving from 100 x 32 to 132
x 64 dot matrix monochrome/grey scale STN LCD with an extra
icon line, integrate all common/segment driver outputs,
voltage generator, internal regulator resistors,
serial/parallel interface, selectable temperature
compensation circuitry, oscillator in one chip to minimize
chip count and external components required in applications.
The devices are designed to adapt the most commonly used
basic command set for easy programming. In addition,
advanced design in zero address setup / hold time enables
the device to match the timing interface with the latest,
fast DSP or MPU protocol directly, a definite need in the
next generation portable telecommunication products system
design.
Technical
Specifications
The
SSD181X series drive from 4 lines 16 English characters per
line to 8 lines 22 English characters per line plus one icon
line. Operating in low voltage 1.8V to 3.5V, the ICs provide
an on-chip 2x, 3x or 4x voltage generator for at most - 15V
high voltage output. On-chip smart bias divider with
internal regulator resistors employs special scheme to
minimize operating current to only several tens uA and also
minimize external components required.
The
devices have a half display mode where the LCD can be programmed
to display with less number of rows (lower mux
ratio). It can further help to reduce LCD power consumption
by 30% during standby mode. Another special icon mode
provides capability to drive as many as 100 icons at low
frequency without additional I/O pins and high LCD drive
voltage (VLCD) requirement. The current
consumption at icon display is typically 7uA only.
The
devices provide selection on serial or parallel interface,
which include Motorola standard serial peripheral
interface SPI, 8 bit 6800-series parallel interface and 8
bit 8080-series parallel interface. Advanced design in
zero
address setup / hold time enables the device to handshake
with the latest, fast DSP or MPU protocol and no need extra
wait state programming effort.
Other features are LCD drive
voltage temperature compensation at 8 selectable
coefficients, 64 level internal contrast control, vertical
scrolling, page blinking and on-chip oscillator.
The
SSD181X is manufactured in CMOS process, available in bare
die (square die design) for COB applications, gold bump
die (slim die design) for COG applications and TAB (slim
die
design). Samples are available now at sample price US$4.0
for bare die and gold bump die, US$5.0 for TAB. For detailed
