San Jose, Calif. - SmartASIC Inc. has introduced two LCD controllers, the SP1015 and the SP1215, optimized for use with LCD PCs-"all-in-one" devices that integrate a PC and an LCD monitor. "Nearly every PC manufacturer will be introducing an LCD PC very soon," said SmartASIC president and chief executive officer C.C. Kau.
The SP1015 supports input resolutions up to XGA, while the SD1215 supports resolutions up to SXGA+. Both interface to Intel's 810/810E DVO port and to the flat-panel interface used by other chip sets.
SmartASICs are said to cut costs by eliminating the TDMS transmitter and receiver chip set common in current LCDs. Both controllers have automatic configuration, panel power sequencing and image scaling, all without an external microcontroller and firmware.
The SP1015 and SP1215 support 12-bit and 24-bit in-put data. Automatic calibration detects the input mode, gauges the horizontal/vertical screen position and synchronizes the clock frequency. Automatic contrast adjustments set the black level and contrast gain. Automatic up- and downscaling expands to full screen for different input modes, and the chips provide true color support automatically, with proprietary, spatial-based dithering and optional temporal-based dithering for 6-bit LCD panels.
The SP1015 and SP1215 use proprietary adaptive interpolation and image-processing algorithms to smooth jagged edges in interpolation, enhance the sharpness of text and eliminate gray shades for maximum contrast and readability.
Samples of the SP1015 and SP1215 controllers are available, with production planned for the first quarter of 2001.
The SP1015 controller is packaged in a 128- or a 160-pin quad flat pack and is priced at $12 in lots of 1,000. The SP1215, with the same packaging, is $15. Both operate at 2.5 volts but have 5-V-tolerant I/O.
