                      Hitachi Releases Large Capacity 64-Mbyte Flash MultiMediaCard
                      -Approximately one-hour music data recording capability-
                      #
                      Hitachi, Ltd. (TSE: 6501) today announced the HB288064MM 64-Mbytes flash MultiMediaCard(TM)*1,
                      for data recording in portable music players and similar products.  
                      Sample shipment will begin in July  2000 in Japan.  The HB288032MM 32-Mbyte model 
                      was also developed and volume production has begun in June in Japan.
                      Using popular compression technology, the 64-Mbyte model can record approximately 
                      one hour of music data, and the 32-Mbyte model approximately 30 minutes, offering 
                      extended recording times for portable music players and similar products.
                      
                      Flash MultiMediaCards are the smallest class flash cards currently available, and 
                      are used for still-picture recording in digital still cameras, data recording in mobile 
                      phones (smart phones), music recording in portable music players, and similar applications.  
                      In the portable music player market, there is a strong demand for large-capacity MultiMediaCards
                      offering long recording times.
                      
                      Hitachi currently produces a 16-Mbyte product to meet this demand, and has now 
                      developed two new MultiMediaCards with capacities of 64- and 32-Mbytes.
                      A MultiMediaCard consists of  flash memory and a controller.  These new products 
                      incorporate 0.25 m, 256-Mbit AND-type flash memory employing Hitachi's Multi-
                      Level Cell technology, and a cell-based IC with a SuperH(TM)*2 RISC microcomputer as 
                      the CPU core.  Employing Hitachi's mounting technology to stack two flash memory 
                      chips, the 64-Mbyte model offers the industry's largest capacity for a flash 
                      MultiMediaCard.
                      
                      MultiMediaCard standardization is undertaken by the MultiMediaCard Association, and 
                      specifications are available to members in System Spec form.  These new products 
                      conform to System Spec Version 2.11.  As with the 16-Mbyte product, the overall 
                      product specifications have been formulated in collaboration with Infineon Technologies 
                      AG.
                      These new products achieve a read speed of 14-Mbit per second and a write speed of 3- 
                      Mbit per second, among the fastest in the industry, while operating on a low voltage of 
                      2.7 to 3.6 V.  As interface of card, both MultiMediaCard mode and SPI mode are 
                      supported, allowing the user to select the most appropriate interface method for a specific 
                      product system design.
                      Support tools for use when designing a system using MultiMediaCards are available from 
                      third-party suppliers, including driver, file manager, and other software*3, hardware such 
                      as an H8S microcomputer-based development platform, and also analytical tools such as 
                      a dedicated MultiMediaCard protocol analyzer*4 useful for signal measurement.
                      The future MultiMediaCard road map covers the development of 128-Mbyte large-
                      capacity cards using 512-Mbit flash memory, and large capacity Secure 
                      MultiMediaCards with content protection function.
