"SH7058F" SuperH Microcontroller
featuring 80MHz high-speed operation and on-chip large
capacity 1-Mbyte flash memory enabling one-cycle access
Tokyo, September 24, 2002Hitachi, Ltd. (TSE: 6501) today announced the SH7058F 32-bit single-chip RISC microcontroller, featuring the industry's fastest operating frequency of 80 MHz and the industry's largest class on-chip flash memory capacity of 1 Mbyte, for use in power-train control fields such as automobile engine control, and FA and similar industrial equipment control. Sample shipments will begin in December 2002 in Japan.
The SH7058F is a successor to the F-ZTATTM*1 microcontroller with on-chip flash memory SH7055F, incorporating a high-performance RISC microcomputer SuperHTM*2 family SH-2 CPU core. Employing a 0.18mm process, the SH7058F the 80MHz operating frequency and the 1-Mbyte on-chip flash memory enabling one-cycle access. These are twice frequency and memory capacity of current SH7055F. The resulting high-speed operation capability and ability to store large programs for complex control makes it possible to implement sophisticated high-performance control systems requiring more precise and finely tuned control in such fields as engine control.
In such fields as automobile engine control, the kinds of control handled are becoming more and more complex, ranging from simple fuel injection control to control for improving fuel consumption, for example. And there has been a trend in recent years toward increasingly complex forms of control such as those related to environmental conservation. There is a consequent demand for the ability to implement sophisticated, high-precision, high-speed control and handle ever larger control programs, together with an urgent need for microcontrollers that make it possible to shorten system development times by enabling control programs and equipment control programs to be modified on-board.
Hitachi has previously released the SH7055F for use in such fields as engine control, featuring a SuperH family equipment-control-oriented SH-2 CPU core together with 40 MHz operation and 512-Kbyte on-chip flash memory. Now, to meet the market need for larger and faster programs, Hitachi has developed the SH7058F featuring the industry's largest class on-chip flash memory capacity of 1 Mbyte, and the industry's fastest operating speed of 80 MHz.
The SH7058F employs a 0.18µm process and incorporates the same SH-2 CPU core as its predecessor. The main features of the SH7058F are summarized below.
< Features >
The package used is a 256-pin QFP. SH7058F is upward compatible SH7055F and programs for the current SH7055F can also be used with easy changes. In addition, the SH7058F includes an on-chip debugging function and the E10A compact emulator or high-functionality E6000 emulator for on-chip debugger use can be used as a development environment, as with the SH7055F.
Hitachi plans to further extend the product lineup with higher-performance models for engine control and other in-vehicle and industrial systems.
< Typical Applications >
In-vehicle control equipment: Engine control, AT control, suspension control
Industrial equipment: FA, sequencers, NC
