Faster memories speed comms applications
Fujitsu Microelectronics has introduced the latest family members of its fast-cycle RAM series, a group of 256Mbit high-speed memories that incorporate the double datarate SDRAM interface.
Fujitsu Microelectronics has introduced the latest family members of its fast-cycle RAM (FCRAM) series, a group of 256Mbit, high-speed memories that incorporate the double datarate (DDR) SDRAM interface The new FCRAMs, which were jointly developed with Toshiba, are designed for high-performance network systems that require very high capacities and speeds of up to 200MHz

Leo aims at European navigation applications
Fujitsu Microelectronics Europe is releasing its Leo FR-V (Fujitsu RISC-VLIW) chip, based on the FR-V architecture announced last year.
The FCRAMs are ideal for use in applications such as enterprise servers, look-up tables and high-speed buffers for network systems.
The new 2.5V FCRAMs are divided into the A Series (which feature 154MHz clock speeds) and the B Series (with 200MHz clock speeds).
Both series use the SSTL-II I/O interface.
Random cycle times for different versions of the A series range from 30 to 40ns with random access time of only 22.5ns.
For the B Series, cycle times range from 25 to 40ns, while an access of 22ns is supported.
The A Series includes the MB81N261647A, with 133 to 154MHz clock speed versions.
The B Series is represented by the MB81N261647B, featuring 167 to 200MHz clock speeds.
Working closely with leaders in the networking and communications markets, Fujitsu has designed the FCRAM to meet these companies' specific requirements for high speed and bandwidth combined with low latency and extremely short random cycle time to serve the exploding data-management markets.
Network system developers need this kind of memory technology for their new generations of equipment.
For example, improvements in the command input system enable increased bandwidth, faster random access times and reduced power consumption.
All these enhancements have been provided with no increase in pin count.
Samples of the A Series will be available in Q2CY01.
The B Series will become available later this year.
All the new FCRAMs are packaged in 66-pin TSOPs. Request a free brochure from Fujitsu Microelectronics Europe ...
