- Fujitsu Launches World’s First Embedded FRAM-LSI that Counteracts Electromagnetic Interference
-
Fujitsu today announced the launch of the MB88R157, an addition to its existing product line of spread-spectrum clock generators, which provide countermeasures against electromagnetic interference on high-frequency clock signals. The new LSI also includes embedded FRAM, an industry first, which features fast rewriting speed and can vary its frequency output over a range of 1 MHz to 134 MHz while mounted on a circuit board. Fujitsu Microelectronic’s circuit design technology reduces the product power consumption in continuous operation by up to 40% in comparison to similar products from other companies.
As it is easy to rewrite parameters in Fujitsu MB88R157 LSI, it is appropriate for a wide range of applications including multi-functional printers, PCs, and mobile phones, as well as for televisions, DVD players, and game consoles.
Tokyo, May 22, 2008 - Fujitsu Microelectronics Limited (FML) today announced the launch of the MB88R157, an addition to its existing product line of spread-spectrum clock generators (SSCG(1)), which provide countermeasures against electromagnetic interference (EMI(2)) on high-frequency clock signals. The new LSI also includes embedded FRAM(3), an industry first, which features fast rewriting speed and can vary its frequency output over a range of 1 MHz to 134 MHz while mounted on a circuit board. In addition, Fujitsu Microelectronic’s circuit design technology reduces the product power consumption in continuous operation by up to 40% in comparison to similar products from other companies. As it is easy to rewrite parameters in this new LSI, it is appropriate for a wide range of applications including multi-functional printers, PCs, and mobile phones, as well as for televisions, DVD players, and game consoles.
In order to avoid the adverse effects of EMI on high-frequency clock signals, which can cause malfunctions of the chip or the entire system, this LSI minutely varies its clock signal.
Fujitsu has offered SSCGs since 2003, and each SSCG has a unique clock frequency depending on the application in which it would be used.
As digital-media devices have become more high-performance and multi-functional, since the number of types of clock signals driving their internal circuits has increased, there is a need for SSCGs that can not only generate unique clock signals, but also vary those signals. In order to meet these needs, Fujitsu Microelectronics developed the MB88R157 with embedded FRAM.
This new product encompasses patent-pending digital frequency modulation control technology and modulation cycle combination technology from Fujitsu VLSI Limited, as well as Fujitsu Microelectronics' own FRAM technology. Fujitsu Microelectronics will continue to provide high value-added SSCG products in future.
