CPU Shack - Hitachi SH-3 32bit RISC

Hitachi's 60MIPS SH-3 Series 32bit RISC Microprocessor Enables Cost-Effective Portable Processing, Consumer, and Wireless Applications

Brisbane, CA - September 16, 1996
Hitachi America, Ltd., Semiconductor & I.C. Division introduces the SH7708 32bit RISC microprocessor, a member of the third generation in the SH Series. The device achieves 60MIPS performance at 3.3V, 60MHz, while dissipating less than 600mW, typical. It has a SuperH(TM) RISC engine with 5-stage pipeline, offers an address space of up to 4GByte, uses a 16bit fixed instruction length for improved code efficiency, and provides single-cycle execution of basic instructions for high performance. Included on-chip are a MMU and 8KByte cache (configurable as 4KByte cache and 4KByte RAM), 32bit internal and 32/16/8-bit external data paths, 32x32+64-->64bit MAC, 32bit/3ch timer, and 2ch user break controller, as well as SCI, RTC, WDT, CPG, PLLs, 8bit I/O, SDRAM/Fast-PageDRAM/PSRAM interface, and 2-slot PCMCIA support. Applications for the RISC microprocessor include PDAs, hard disk drives, cellular phones, set top boxes, electronic games, navigation systems, networking equipment, printer network cards, and digital cameras.

Hitachi is the number one supplier of RISC devices worldwide, with shipments of SH devices exceeding
1.5 million per month. A 100MHz, 100MIPS SH-3 version is expected in early 1997.

Feature Benefit

Single-cycle instruction for basic instructions Higher performance; clock speed is as fast as 60MHz

16bit instructions; upward compatible with SH Series Efficient code density; developers can use familiar tools

Higher performance: 60MIPS Can implement user systems with improved performance

MMU + 8KByte cache (or 4KByte cache/4KByte RAM) Allows more effective systems management

32bit internal and 32/16/8bit external data paths Provides fast, flexible data processing, while enabling the use of cost-efficient peripheral devices

Low voltage (3.3V), low power (<600mW, typical) Extends battery life of portable systems

Large address space and enhanced direct memory interface Direct interface to SDRAM/Fast-Page DRAM/SRAM/ burst ROM eliminates need for additional glue logic

MAC32 unit 32/16-bit DSP functionality for fast computations

Selective integration (peripherals include timers, WDT, PLLs, UBCs, SCI, I/O...) Aids the design of minimal chip-count systems for "Personal Access" applications

QFP-144 Facilitates the engineering of compact system designs

Hitachi Part Number HD6417708F60 (60MHz, 3.3V, QFP-144)
