SYSTECH LIMITED ANNOUNCES A NEW MEMBER OF
DISPLAY CONTROLLER CHIP FOR PORTABLE TELECOMMUNICATIONS
SMART HANDHELD APPLICATIONS AND OFFICE AUTOMATION EQUIPMENTS
A
New Controller That Designed for Compact Color Graphic LCD
Display
Hong
Kong, China ~ Oct 2, 2000 - Solomon Systech Limited
today
announced the release of the SSD1901A Display Controller
with Embedded Memory, a member in the new display
controller
series, which is low power, low cost and feature rich.
The
SSD1901A is a TFT LCD display controller with an embedded
80Kbyte SRAM display buffer. The controller is
designed for mobile communications products, smart handheld
devices, handheld PCs, office automation equipments and
other small embedded applications with LCD display where
battery life is major concern. The large built-in memory
enables SSD1901A to support up to 320x240 (quarter VGA)
displays at 8-bit/pixel color-depths out of 4096 color
palette. The SSD1901A also incorporates virtual display
area
(panning), hardware window filling, floating window and
color inversion functions. These features, combined with
the low power consumption and small footprint package
(TQFP 80),
make the new controller an ideal single-chip display
solution for a variety of applications, including the latest
generation of 3G mobiles, video phones, and color Palm-size
PCs.
The
devices are designed to adapt the most commonly used
MCU for easy programming. In addition, the LCD controller
can
interface with the mobile TFT modules or D-TFD panels.
Technical Specifications
The SSD1901A
embedded 80Kbyte SRAM display buffer. This controller can
use different I/O voltage from the core voltage so that a
wide choice of I/O devices which communicate within 2.5V ~
3.3V can be selected. The extra 4 GPIO pins save MPU I/O pin
in controlling the peripherals.
The device can interface with on a wide
range of MPUs, which include Hitachi SH3, SH4 and Motorola
MC68K series. The maximum input clock frequency can be up to
50MHz.
There are many value-added features to
make the programming easier. The virtual display area makes
the image larger than the actual panel size through panning.
Window filling simplifies the data update process for an
image in a window area on the display. Floating window mode
allows an image in a window area moving without erasing the
original image data. And different power save modes make it
an ideal chip for power consumption concern applications.
The
SSD1901A is manufactured in CMOS process, packaged
in 80pin thin QFP (12mm x 12mm x 1.4mm). Samples will
be
available in Nov 2000 at sample price $8.00. For more
information on SSD1901A specifications, please contact
