【RH850/D1x】

RH850/D1x MCU的主要特点：

(1) 降低了系统物料成本

RH850/D1x MCU结合了大容量RAM(最大3.5MB)和瑞萨新开发的由高效“瑞萨图形库”支持的高端功能图形引擎。这有助于降低RAM使用量，且无需使用外部高速DRAM即可实现高清LCD显示。此外，由于未使用外部高速DRAM，系统可设计在低成本的四层印刷电路板上。

(2) 提供可扩展开发功能

通过结合仪表控制和车载网络等常用基本功能，瑞萨推出的七个产品系列中的22种产品可提供多种图形功能和成本选择。丰富的产品线可提供更好的软件重用性和可扩展的解决方案，从而可开发出适用于仪表盘系统的通用平台。这些可扩展开发功能可缩短软件开发周期并降低开发和维护成本。

(3) 智能开发

RH850/D1x结合了高端功能图形引擎，允许在大显示屏上创建高精度动画，从而满足中端汽车的需求。此外，RH850/D1x还能实现更具表现力和可视性抬头显示器(HUD)。由于RH850/D1x图形引擎支持OpenVG 1.1标准，HMI开发工具支持API标准，因此开发周期可进一步缩短。

(4) 支持平视显示器

RH850/D1x MCU具有自动根据车辆设计(如挡风玻璃)校正视频输出的功能。输出视频数据可进行扭曲，从而可在无任何帧延迟的前提下适应任意形状。这一功能使抬头显示器(HUD)能够添加到仪表盘中。

(5) 功能安全

为确保仪表盘系统的功能安全，RH850/D1x MCU具有检测系统故障的功能，以及实时监控警告档位是否正确等重要安全信息的监视功能。

　　DESCRIPTION (500 watt)

　　This 3 pin Transient Voltage Suppresor offers 2 unidirectional or 1bidirectional protection at the board level from voltage transientscaused by electrostatic discharge (ESD) as defined by IEC 1000-4-2,electrical fast transients (EFT) per IEC 1000-4-4.

　　Unidirectional protection, can be accomplished by connecting theInput/Output lines to pins 1 and 2 and pin 3 to common or ground. In abidirectional configuration pin 1 or pin 2 is connected to the

　　Input/Output line while the opposite pin is connected to common or

　　ground. Pin 3 is not connected. The SM03 thru SM36 product provides board level protection from staticelectricity and other induced voltage surges that can damage sensitive circuitry.

　　These TRANSIENT VOLTAGE SUPPRESSOR (TVS) Diode Arrays protect 3.0/3.3 Volt components suchas DRAM’s, SRAM’s, CMOS, HCMOS, HSIC, and low voltage interfaces up to 36 Volts. Because of thephysical size, weight and protection capabilities, this product is ideal for use in but not limited to

　　miniaturized electronic equipment such as hand-held instruments, computers, computer peripherals andcell phones.
