Hitachi Releases 78MIPS SH-DSP with Built-in Large Capacity Single Power Supply Flash Memory

- Enables quicker development of high performance systems for consumer products, OA and industry -

To increase program sizes, reduce product development periods, improve device specifications, and modify of control data, microcontroller programs often need to be rewritten or modified. In this current situation, field programmability is required to readily enable rewriting and adjustment of microcontroller programs during the course of development, and sample production, at the start of volume production and during mass production of electronic devices with a built-in microcontroller. In response, Hitachi developed the "F-ZTAT ^TM*2" microcontroller with built-in flash memory and has already released 15 products including 8- bit, 16-bit, and 32-bit versions. The new SH-DSP products are for multimedia devices that need to rapidly process a large volume of complex data (video and audio data, for example) such as car navigation systems and digital video cameras, and are also intended for high-performance industrial devices such as high-speed high-precision servo controllers. By using a SH-DSP as the core, the products can rapidly process large amounts of complex data in multimedia devices.

In addition to the 78 MIPS performance, the SH7065F incorporates 3.3V single power supply large capacity flash memory of 256k bytes. Most of the instructions that require the highest processing speed in the systemcan be stored in the built-in flash memory and executed in one cycle. The SH7065F also incorporates abundant peripheral functions including DMAC (direct memory access controller), a powerful timer function, serial I/O, an A/D converter, a D/A converter, and a direct connection function with external memory (SRAM and DRAM (supports EDO)).This enables performance enhancement anddownsizing of devices. In addition, in the same way as for the existing F-ZTAT^TM microcontroller, these products support collective erasing and division of the flash memory into large/small blocks (12 divisions) and erasure of specific blocks. The latter function is effective for adjustment of control data in application systems. The SH7410F has a built-in 3.3V single power supply flash memory of 48k bytes, and can be used to advantage in fields that require high-speed processing, such as digital still cameras, by reducing development periods and enabling specification changes to be flexibly implemented.

The SH7065F and SH7410F can be used with existing development software. In terms of hardware, these products can use the E8000 emulator and the SH7410F can also use the E10 simple emulator. Looking to the future, Hitachi is developing the SH7065M, which has a built-in mask ROM of 256 bytes.

Supplementary information
These products SH7065F and SH7410F use a 0.35 micrometers aluminum 3-layer CMOS process and have a performance of 78 MIPS at 3.3V operation using a SH-DSP with built-in 32-bit DSP as the CPU core, and therefore are suitable for multimedia devices and high-performance industrial devices.

Features
SH7065F
1. Large capacity single power supply flash memory. In each of the processes of sample development, production start, and mass production, microcontroller programs and control data can be rewritten onboard. This enables reduction of a development period and also facilitates the handling of specification changes such as version upgrading after delivery. Since a pressure-rise circuit is incorporated in LSI, no separate power supply (for instance 12V) for writing and erasing flash memory data is required, thereby facilitating the designing of the power supply of the device. 2. Powerful peripheral functions
The SH7065F incorporates the following peripheral functions: Direct connection function for DMAC and external memory (SRAM/DRAM), motor management timer (MMT) that can output 6-phase non-overlapping wave forms for inverter driving without program intervention, and serial interface (SCI) with FIFO memory. This enables enhancement of system functions and cost reduction and, therefore, the product is most suitable for advanced performance industrial devices such as motor control devices.

SH7410F
1. High-speed single power supply flash memory for DSP operation.
In each of the processes of sample development, production start, and mass production, microcontroller programs and control data can be rewritten onboard. This enables reduction of a development period and also facilitates the handling of specification changes such as version upgrading after delivery. The SH7410F incorporates 48k- byte X/Y flash memory byte for DSP operation and can read data at 60MHz/1 cycle. Since a pressure-rise circuit is incorporated in LSI, no separate power supply (for the instance 12V) for writing and erasing flash memory data is required, thereby facilitating the designing of power supply of the device.
2. Powerful peripheral functions
The SH7410F incorporates the following peripheral functions, enabling increased processing speed and downsizing of emulators: Direct connection function for DMAC and external memory (SRAM/DRAM), peripheral functions such as UART and synchronous serial interface, andserial debugging interface for handling the JTAG^* interface standard

Development environment
As the development environment of the SH7065F, the following software and hardware products are made available.
Software: Cross C compiler, cross assembler, cross simulator, and debugger Hardware: Real time emulator (E8000)
