Tokyo, April 19, 2001 ---Fujitsu Limited today introduced a new stacked Multi-Chip Package (MCP) with 64Mbit dual-operation flash memory and 32 Mbit Mobile FCRAM(TM), designed to provide the low power and high density required for new cellular telephones.
Fujitsu's new MB84VD23483EJ combines the NOR-type flash memory and the mobile FCRAM with an asynchronous interface, which is compatible with static RAM. Power consumption for flash in standby mode is only five microamps, maximum, and only 100 microamps for mobile FCRAM. In power-down mode, consumption is only 10 microamps. Access times are typically 90ns for both flash and FCRAM. Power-supply requirements are 2.7V to 3.1V. The MCP's low power, high density and SRAM-compatible interface make it an excellent device for the new generation of mobile phones that provides e-mail, imaging, Internet access, games and other features.
In recent years, services and functionality provided by mobile phones and other wireless communication devices that utilize digital and Web-based technologies have been rapidly expanding. And in May, the IMT-2000 next-generation mobile communication system is scheduled to begin commercial service in Japan, representing the first stage of a worldwide trend toward comprehensive mobile communication devices that provide users with features ranging from Internet-page downloads to video games.
Fujitsu's new stacked multi-chip package meets next-generation mobile phone manufacturer's low power, high speed and high-density requirements. The new MCP offers Fujitsu's innovative FlexBank(TM) Architecture embedded in the flash memory, which allows flexible allocation of data or programs to banks according to customers' system requirements. Dual operation flash architecture enables the device to read from one partition while programming or erasing in another, making it possible to achieve high-speed processing. The new MCP continues Fujitsu's worldwide leadership in leading-edge packaging solutions for next-generation cellular, computing and networking designs. Samples of the MB84VD23483EJ MCP in plastic BGA packages will be available for worldwide distribution by the end of May, and mass production will start in October. Pricing in Japan will start at approximately 6,000 yen each (excluding tax).
