Fujitsu Launches Embedded-FRAM LSI for Digital TV that Enables Simultaneous Use of 4-channel HDMI Connector Ports

It also stores display data, such as resolution, that is read by audiovisual digital entertainment devices when they are used with digital TVs.

Sample shipment of the MB85RF402 started in November 2007.

This new LSI supports the HDMI connector interface specification standard for digital audiovisual 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 digital TVs enables high-speed factory programming of extended display identification data (EDID) and reduces production costs by lessening the number of parts required and reducing mounting space, according to Fujitsu.

Features include:

• One chip supports up to four HDMI ports. This product is equipped with a four-channel display data channel (DDC) interface, which communicates the display data sent from the HDMI ports.

• Cost reduction through fewer parts and reduction of required space. With this LSI, display data from a specific HDMI port can be automatically searched, and matching data stored in the FRAM can be automatically converted as output. The memory function for display data, which previously required four electrically erasable programmable read-only memory (EEPROM) cells, can now be handled with one cell. As a result, fewer parts are required.

• Reduction of time required for data programming process during manufacturing of digital TVs. Previously, the memory for display data required separate memory chips for each HDMI port. By combining the memory for four ports into one high-speed data-writing FRAM block on this new LSI product, the time required for the factory programming of data during the production of digital TVs is shortened, Fujitsu said.
