|Hitachi Releases SH7705 Ultra-Low-Power 32-Bit SuperHTM RISC Microprocessor|
| Large 32-Kbyte cache memory and comprehensive on-chip peripheral functions including USB Function, enabling implementation of high-performance, low-power-consumption digital home appliances, portable information devices, and OA products |
Tokyo, July 22, 2002 Hitachi, Ltd. (TSE: 6501) today announced the SH7705 ultra-low-power microprocessor for use in digital home appliances such as digital still cameras and video printers, portable information devices such as electronic personal organizers and electronic dictionaries, and OA products such as fax machines and color printers. It incorporates an SH-3 32-bit CPU core of SuperH*1 RISC microprocessor family, large 32-Kbyte cache memory and a various kind of peripheral functions such as a USB (Universal Serial Bus) Function. Sample shipments will begin in August 2002 in Japan.
The SH7705 has an SH-3 SuperH family CPU core designed for low-power-consumption products, and is suitable for use in embedded systems that require high performance and low power consumption. A 0.18-µm CMOS process is used, and ultra-low power consumption of 200 mW (typ.) at 133 MHz operation has been achieved. The SH7705 also incorporates large 32-Kbyte cache memory, four times the capacity of Hitachi's existing device, as well as a rich variety of on-chip peripheral functions including a USB Function, making possible end-products that offer lower power consumption, higher performance, and lower price.
Recently, In the fields of digital home appliances, portable information devices and OA products, end-products with a USB interface for connection to external devices are increasing, and Hitachi has previously released the SH7622, with an SH2-DSP CPU core and an on-chip USB Function, as a product designed for this market. However, with the larger data volumes and processing speeds associated with end-products that handle voice and image data, there is an ongoing trend toward even higher system performance and functionality. At the same time there is a demand for lower power consumption for such products as portable information devices, and a growing need for semiconductor devices that will meet these needs together with the requirement of lower end-product cost.
In response to these market demands, Hitachi is releasing the SH7705 32-bit RISC microprocessor that offers higher performance though the use of an SH-3 CPU core, a upper model than the SH2-DSP, together with even lower power consumption than existing device. Features of the SH7705 are summarized below.
< Product Features >
Two packages are available: a 208-pin LQFP (28 mm × 28 mm) and a 208-pin CSP (12 mm × 12 mm). On-chip debugging functions (H-UDI and AUD) are incorporated, enabling real-time emulation to be carried out at the maximum operating frequency using an E10A PC card emulator. In addition, SolutionEngine®*2 for the SH7705 is available as an application development platform, facilitating speedy and efficient software development.
Hitachi plans to further enhance its lineup of products for use in
digital home appliances, portable information devices, and OA products,
and to develop products offering significantly higher performance
and lower power consumption.
