　　在瑞萨RL78/G13系列演示套件审查的手

　　线之间的演示套件和开发系统变得很难界定，前者包括快速、低功耗单片机用大量内存；足够的外设处理几乎任何类型的应用程序；1-1／4英寸的液晶屏幕；一套完整的开发工具；内置的调试器；十几个例子程序，以建立自己的框架；一个代码生成工具；最后的电路图和格伯文件。如果有什么东西不见了，那就不明显了。

　　The Renesas Demonstration Kit （RDK） for the RL78/G13 MCU （see Figure 1） provides a multifunction platform for evaluating the ultra-low-power Renesas RL78/G13 MCU. Numerous peripherals include a speaker， microphone， infrared emitter， infrared detector， LCD screen， 3-axis accelerometer， temperature sensor， and ambient light sensor， all of which can be exercised by the sample code included with the kit. The RDK includes IAR KickStart tools and an integrated Renesas TK debugger.

　　The RDK is built around the Renesas 16-bit， 32 MHz RL78/G13 – a general purpose， ultra-low-power CISC MCU intended for a wide range of consumer and industrial applications. The G13 is currently available in fourteen different packages ranging from the R5F101FAAFP#V0 with 16 KB of flash memory to the R5F100MLAFB#V0 with 512 KB of flash and 32 KB of RAM. The RL78 includes an on-chip 32 MHz oscillator， but the chip can quickly switch to the 32 kHz subsystem clock for ultra-low-speed operation. Also included on-chip is single power supply flash memory， a debug function， multiplier and divider/accumulator， interrupt function， four timers， an 8/10-bit ADC， 16 to 120 I/O ports， and considerably more. Renesas was good enough to put one of the larger chips in the RDK.
