Toshiba Has First Microcontroller with SD Memory Card Controller --16-bit CISC MCU Also Integrates USB Controller--

    TOKYO, July 23 /PRNewswire/ -- Toshiba Corporation today announced the
 world's first microcontroller dedicated to supporting the SD memory card
 standard and the simplified design of high-capacity digital audio players.
     The new 16-bit Complex Instruction Set Computer (CISC) incorporates an SD
 memory card controller that supports interfacing between an application
 platform and an SD memory card.  It also integrates a Universal Serial Bus
 (USB) controller, enabling direct downloads to SD memory cards from PCs
 equipped with a USB port.  Integrated with either of Toshiba's TC94A02F,
 digital signal processor, the new LSI enables configuration of a total
 solution for SD digital audio player design.
     The SD memory card is fast establishing itself as the memory card of
 choice in applications that require high levels of data security.  Chief among
 these are SD digital audio players offering copyright protection in line with
 the Secure Digital Music Initiative (SDMI).  Other applications include
 reader-writers that download data from PCs to SD memory cards.
     Samples of the new LSI will be available from the fourth quarter of 2001,
 at a sample price of US$20.  Mass production will start in the first quarter
 of 2002.
 
     Development Background
     Advances in compression technology for digital audio are fueling demand
 for digital audio players combining advanced copyright protection with a high
 storage capacity.  The NAND-flash-memory-based SD memory card offers the
 optimum solution, and demand for products supporting SD is expected to take
 off dramatically as content suppliers advance plans for music distribution
 over the Internet.  The new microcontroller meets market demands for a price
 competitive, low power device that integrates both SD and USB controllers.
