The new LSI also includes embedded FRAM (Ferroelectric Random Access Memory), claimed to be an industry first, which features fast rewriting speed and can vary its frequency output over a range of 1MHz to 134MHz while mounted on a circuit board.
In addition, Fujitsu Microelectronics' 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 suitable 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.
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 Ltd, as well as Fujitsu Microelectronics' own FRAM technology.
The MB88R157 started sample shipping on May 22, 2008. |
