Renesas公司的RL78/G13采用新型RL78 CPU內(nèi)核，工作頻率高達(dá)32MHz，工作電壓1.6V-5.5V，適合各種類(lèi)型的消費(fèi)類(lèi)電子和工業(yè)應(yīng)用，如工業(yè)自動(dòng)化，家庭自動(dòng)化，電動(dòng)工具，白色家電，計(jì)量，醫(yī)療，照明和馬達(dá)控制。本文介紹了RL78G13主要特性，方框圖，RL78 RDK評(píng)估板目標(biāo)應(yīng)用和主要特性，方框圖，電路圖，材料清單和PCB元件布局圖。

The RL78/G13 are built around the new RL78 CPU core, which is based on the 78K0R CPU core, and can be applied to all sorts of consumer and industrial applications.

The RL78 Family of microcontrollers (MCUs) combines advanced low power technology, outstanding performance, and the broadest line-up in its class for the most demanding 8- and 16-bit embedded applications.

The RL78 MCUs‘ innovative “Snooze“ mode achieves ultra-low power by allowing ADC operation and serial communication, all while the CPU is turned off. This makes the RL78 MCUs best in class for low power applications.
