Embedded-FRAM LSI enables 4 HDMI connector ports

Fujitsu Ltd has announced what it claims as the world's first embedded-FRAM LSI for DTVs that enables simultaneous use of four-channel HDMI connector ports—such as for multiple DVD recorders, camcorders and video game consoles—and which stores display data, such as resolution, that is read by audio-visual digital entertainment devices when they are used with DTVs.

This new LSI from Fujitsu supports the HDMI connector interface standard for digital audio-visual equipment, and combines on a single embedded FRAM chip the display data memory for four HDMI connector ports, which previously required separate memory for each port. Using this LSI in DTVs enables high-speed factory programming of Extended Display Identification Data (EDID) display data, and in addition facilitates reduction of overall production costs by lessening the number of parts and the mounting space required.

In recent years, flat-screen and other DTVs have needed to be equipped with a large number of digital interfaces to accommodate connections to DVD players and recorders, camcorders, game consoles and other digital entertainment equipment. Use of HDMI is spreading as the most standardised specification that enables high-quality audio and visual output, in addition to single-cable transmission of control signals for automatic equipment control. Via an HDMI connection, products that output video or audio, such as DVD players, first read the display data, such as display resolution, and then automatically adjust their output to suit the display.

By combining on a single embedded-FRAM chip the display data memory for four HDMI connector ports, the new LSI can reduce the cost of DTVs while preserving their versatility as the centerpiece of home entertainment systems.

Sample shipment of the MB85RF402 started Nov. 12. Pricing is Rs.32.43 (82 cents) each for 10,000 units.
