September 1990 Edition 1.0 DATA SHEET c O FUJITSU MB8298-251-35 CMOS 256K-BIT HIGH-SPEED SRAM 32K Words x 8 Bits High-Speed Static Random Access Memory The Fujitsu MB8298 is a high-speed static random access memory organized as 32,768 words x 8 bits and fabricated with CMOS technology. To obtain a smaller chip size, the cells use NMOS transistors and resistors.The MB8298 is housed in 300 mil plastic DIP and SOJ packages and a 45Q-mil SOP package. All pins are TTL patible and a single +5 V power supply is required. The MB8298 has low power dissipation, low cost, and high performance, and it is ideally suited for use in microprocessor systems and other applications where fast access time and ease of use are required. .. - Organization: 32,768 words x 8 bits - Static operation: no clocks or timing strobe required - Access time: 1M - t ACS - 25 ns max.
