New 32-Bit RISC MPU From Toshiba Incorporates One Megabyte of Mask ROM or Flash Memory Plus 40 Kilobytes of RAM

"Based on the MIPS RISC architecture, Toshiba developed the flexible, configurable TX19 core to meet the new portable digital consumer market requirements. The TMP1962 is the first product in a series of second- generation TX19-based processors that combine large-capacity memory and many integrated functions," said Farhad Mafie, vice president of the ASSP Business Unit at TAEC. "Toshiba has been able to capitalize on its development tools and software investment in the MIPS architecture to develop all the necessary tools for this new family of devices."

"Toshiba's customers can ensure their software investments are secure for years to come by leveraging the breadth of optimized software available for the MIPS architecture," said Jack Browne, vice president of worldwide sales for MIPS Technologies. "The TX19 joins Toshiba's broad line of MIPS- compatible ASSP microprocessors, and is another example of the ongoing innovation for which Toshiba is well known throughout the semiconductor industry. We congratulate them on this unique product design."

The new processor is built around a TX19 core that enables high code efficiency and low-power operation and has on-chip ROM and RAM that can be accessed in a single clock cycle. It incorporates various peripheral functions, including 17 channels of versatile 8-/16-/32-bit timers, 24 channels of analog-to-digital (A/D) converters, and seven channels of serial interfaces, enabling control of large-scale programs on a single chip. These features make the new processor well-suited for personal portable equipment applications, including digital video cameras (camcorders). Mr. Mafie noted that a major Japanese company has already designed the device into a digital camcorder.

According to Don Schneider, business development manager of the ASSP Business Unit at TAEC, "In order to reduce the overall system cost, system power consumption, and provide a high level of integration of the new TMP1962, Toshiba engineers decided to incorporate a large amount -- 1M-byte -- of on-chip ROM or Flash Memory as well as a direct memory access (DMA) controller, timers, general-purpose serial interfaces, A/D converters and watchdog timer. The processor is housed in a compact 13mm x 13mm 281-pin fine-pitch ball grid array (FBGA) package that make it ideally suited for size-constrained, low-power applications such as audio/video applications or systems with biometrics inputs."

   Key Features
   Key features of the MPU are as follows:
    -- Incorporates 1M-byte of ROM or Flash Memory and 40 Kbytes of RAM and
       thus provides a single-chip solution for control of large-scale
       programs.
    -- Compact 281-pin FBGA package, 13mm x 13mm, 1.4mm thick, saves space
       and contributes to development of smaller systems.
    -- Incorporates 11 external interrupt inputs and 14 key-on wake-up
       inputs, which are suitable for applications that use key input to
       wake up a system from standby mode.
    -- Flash memory version supports on-board ROM data reprogramming for
       easier software debugging.
    -- On-board debug function facilitates system development.

  Development Background

For many years Toshiba's MIPS-Based RISC processors have been used in office automation, digital consumer, and networking applications where a high level of integration and high-performance are critical. As more and more functions are added to portable digital consumer products, the need for processors with high-performance, low-power, and a high level of integration is becoming more and more apparent. Customers are also demanding smaller, lighter devices with longer battery life. This compels manufacturers to reduce parts count and challenge the limits of low-power consumption. Toshiba's new addition to the TX19 Family of 32-bit TX System RISC microprocessors is an ideal solution to such requirements, offering large- capacity memory and low-power-consumption operation at the same time.

Pricing and Availability

ROM code acceptance for the mask ROM version, the TMP1962C10BXB, is scheduled to start in February 2004; sample pricing is planned to be $12.50 each in 100-piece quantities. Samples of the flash memory version, the TMP1962F10AXB, are scheduled to be available in December 2003 at a planned price of $28.95 each in 100-piece quantities. Volume production of both versions is slated to start in March 2004 at an initial run rate of 500,000 units per month.
