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 ¦Ìm, 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. Notes: 1. MultiMediaCard is a trademark of Infineon Technologies AG of Germany. 2. SuperH is a trademark of Hitachi, Ltd. 3. Driver and file manager software is marketed by AI Corporation in Japan. 4. An H8S microcomputer-based development platform and dedicated MultiMediaCard protocol analyzer are marketed by KOKUSAI ELECTRIC ALPHA Co.,LTD. < Typical Applications > Portable music players, toys, game machines, and similar portable entertainment products Portable imaging products, including digital video cameras and digital still cameras Palm-size PCs, electronic schedulers, and similar portable information devices Smart phones, pagers, and similar portable communication products < Prices in Japan > ProductName Capacity Price HB288064MM 64-Mbytes Open price HB288032MM 32-Mbytes < Specifications > Item Specifications Memory capacity 64 Mbytes (HB288064MM), 32 Mbytes (HB288032MM) Interfaces MultiMediaCard SPI (Serial Peripheral Interface) System performance Read: 14-Mbit/sec typ.
