Renesas SH7269 266 MHz MCU开发方案

Renesas公司的SH7269是采用SH2A-FPU核的高性能MCU,片上SRAM为2.5MB,能直接显示WVGA(800x480象素)而不用外接SRAM,CPU工作频率266 MHz ,对设备控制和数字音频信号处理提高性能,主要用在汽车音频,HDD音频和网络音频,仪表盘和汽车显示系统以及机器人等.本文介绍了SH7269主要特性,方框图,以及SH7269 RSK评估板主要特性,方框图,电路图和评估板PCB元件布局图.

The SH7268, SH7269 Group are high-performance microcontrollers incorporating SH2A-FPU cores. The SH7268, SH7269 Group share the following features: (1) large-capacity 2.5 megabyte (MB) on-chip SRAM that is 1.7 times the capacity of the Renesas Electronics’ existing MCU (SH7266) allowing display of WVGA size (800 x 480 pixel) images without any external SRAM. (2) Increased maximum CPU operating frequency by approximately 1.8 times (266 MHz), which provides increased performance for device control and digital audio signal processing. (3) Additional functionalities, such as a 2D graphics accelerator that conforms to the OpenVG™ 1.1 standard, the industry standard graphics processing programming interface (API) for embedded equipment.

This LSI is a single-chip RISC (reduced instruction set computer) microcontroller that includes a Renesas-original RISC CPU as its core, and the peripheral functions required to configure a system.
