San Jose, Calif. Renesas Technology America released the SH7764 microprocessor, a 32-bit device with a maximum operating frequency of 324 MHz. The chip incorporates the SuperH Family's SH-4A CPU core, a 2D graphics engine, Ethernet controller, USB Host/function controller, ATAPI hard-drive controller and LCD controller. It is suited for the needs of multimedia and office automation applications. The microprocessor also supports standard operating systems such as embedded Linux and Windows CE for development of platforms.
The SH7764's SH-4A CPU core has a 32-Kbyte cache memory, an on-chip 16-Kbyte RAM, and a 108 MHz 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 (giga floating-point operations per second) maximum computational performance at single precision operations, and provides hardware support of sine/cosine operations and vector arithmetic operations for fast 3D graphics drawing.
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).
