Embedded-FRAM device for digital TV enables simultaneous use of 4-channel HDMI connector ports
Fujitsu Microelectronics Europe has announced the development of what it says is the world’s first embedded-FRAM device for digital TVs that enables simultaneous use of four-channel High-Definition Multimedia Interface connector ports - for connecting devices such as 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 digital TVs.
This new device from Fujitsu supports the HDMI connector interface specification 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 device in digital TVs enables high-speed factory programming of Extended Display Identification Data (EDID)(*3) and, in addition, facilitates reduction of overall production costs by lessening the number of parts required and reducing the necessary mounting space.

In recent years, flat-screen and other digital TVs have needed to be equipped with a large number of digital interfaces to accommodate connections to DVD players and recorders, camcorders, games consoles, and other digital entertainment equipment. The use of HDMI, a digital multimedia interface, 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 the display data memory for four HDMI connector ports, on a single embedded-FRAM chip, the new device can reduce the cost of digital TVs while preserving their versatility as the centrepiece of home entertainment systems.
