The SH7641, a 32-bit SuperH RISC microprocessor from Renesas, features 144-Kbyte SRAM, 16-Kbyte cache memory and comprehensive peripheral functions including a multifunction timer unit for motor control.
The device is suitable for use in industrial products such as AC servos, inverters, vending machines and surveillance cameras, and OA and consumer devices such as video printers and bar code readers.
The SH7641 is based on the SH3-DSP CPU core and offers CPU performance of 130 MIPS and DSP performance of 200 MOPS at a maximum operating frequency of 100 MHz. The 144-Kbyte SRAM can be read or written in a single cycle, and this, coupled with the benefits of the on-chip cache memory, enables fast execution of system programs, making it possible to handle the realtime processing demanded by industrial equipment. Also, the provision of DSP functions allows high-speed execution of middleware for JPEG or similar image processing and MP3 or similar voice processing.
The device features a comprehensive set of on-chip peripheral functions including eight 10-bit A/D converter channels and four DMAC channels. It offers a range of interfaces including a single-channel USB function and also features a single channel I2C bus interface and a three-channel serial communication interface with a 16-stage FIFO.
