Fujitsu Releases New 32-bit RISC Microcontroller, the MB91302

Direct Memory Access Enables High-Speed Data Processing

Fujitsu Limited

Tokyo, April 08, 2003

Fujitsu Limited today announced that it has jointly developed with Fujitsu VLSI Limited the MB91302, a new 32-bit high-performance RISC microcontroller that implements direct memory access for high-speed data transfer. The new microcontroller, which is especially well suited for DVD players, digital cameras, printers, video games, and other applications that require high-speed throughput, is available starting today.

New 32-bit RISC Microcontroller - MB91302

The device offers on-chip interfaces for a complete range of memory types, including synchronous DRAM (SDRAM), enabling direct memory access. This significantly increases data transfer speeds and simplifies circuit board design due to a smaller parts count, resulting in cost savings.

Pricing and Availability (Japan)

Name Price (excl tax)
MB91302 1,200 yen

Sales Target: 300,000 units/month

Special Features of the MB91302

  • Interfaces for all memory types
    The MB91302 implements interfaces for SDRAM, SRAM, asynchronous ROM (EEPROM, mask ROM), flash memory, and fast cycle RAM (FCRAM). It enables direct access to any type of memory, offering high-speed data transferring, reduced parts-count for simplified circuit design, and cost savings.
  • Equipped with high-speed direct memory access controller (DMAC)
    The MB91302 also provides a high-speed DMAC circuit dedicated to controlling data transfer. This technology makes it possible to move data directly between an external device and a memory, without passing through the CPU, thereby doubling the data transfer rate.
