Renesas公司的RL78/G13采用新型RL78 CPU內核，工作頻率高達32MHz，工作電壓1.6V-5.5V，適合各種類型的消費類電子和工業應用，如工業自動化，家庭自動化，電動工具，白色家電，計量，醫療，照明和馬達控制。本文介紹了RL78G13主要特性，方框圖，RL78 RDK評估板目標應用和主要特性，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.
