Renesas SH7764 SuperH Microprocessor Supports Embedded Linux

Renesas announced it’s new  SH7764 microprocessor.  The SH776 is a 32-bit MCU, can be clocked up to 324MHz. This chip incorporates the SuperH SH-4A CPU core and an array of peripheral and communication functions, including Ethernet controller, 2D graphics engine, ATAPI HD controller, USB Host controller,  and LCD controller. The SH776 microprocessor is targeted to office automation and multimedia applications.

The 583 MIPS SH7764 microprocessor supports embedded Linux and Windows CE operating systems. These operating systems can reduce development cost and time.

The SH7764's SH-4A CPU core has 32 Kbytes cache memory for instructions and 32 Kbytes cache memory for data. The chip also offers an on-chip 16-Kbyte RAM, and a 108MHz 32/64-bit bus for connections to external high-speed SDRAM. An on-chip floating-point processing unit (FPU) supports single- and double-precision arithmetic operations, achieves 2.3 GFLOPS maximum computational performance at single precision, suitable for fast 3D graphics drawing.

The E10A-USB on-chip debugging emulator is available as a development environment, and SH7764 system development can be carried out efficiently using the high-performance user debug interface (HUDI) and advanced user debug (AUD) functions. The High-performance Embedded Workshop software package includes a comprehensive suite of software tools and offers project management capability.

On-chip peripherals for implementing storage functions include the ATAPI controller, a NAND flash controller, and a memory card controller. Support for communication functions is provided by the Ethernet controller and USB interface, a serial communication interface with FIFO (first-in-first-out), and an I2C bus interface. On-chip display functions comprise the 2D graphics engine for screen drawing and the LCD controller and a digital RGB output function for display purposes. Other built-in functions are a serial sound interface (SSI) for digital audio playback, 32-bit timer, watchdog timer (WDT), and DMA controller (DMAC).

Available in April 2007. Price: $25 (Consumer grade) to $29 (Automotive grade).
