Up to 54 MHz operation and built-in remote control receiver and HDMI-CEC for linking to home appliances


The RX634 Group operates at single voltage supply of 3.3 V but also at 5 V and performs at up to 54 MHz CPU clock. The RX634 group memory lineup offers up to 2 MB code flash, 128 KB RAM and 32 KB Data flash embedded. RX634 is available in a 144-pin package. Compared to the RX630 group the RX634 added HDMI-CEC function and Remote Control Signal Receiver function which are typical required features for digital home appliances. At the same time RX634 has been feature optimized by removing CAN, USB and RTC function to suit the market needs even better. Therefore RX634 suits ideally as a multimedia devices group, due to feature set as well as high performance. In addition RX634 group incorporate multi function timer (MTU2) and high speed 12-bit A/D converter enable to hold 3 channels at the same timing, which are typically required for industrial motor control applications.

标题 描述
e² studio 基于CDT插件的集成环境 (IDE),支持全球流行的开源集成开发环境“Eclipse”和C/C++语言开发。
CS+ 该集成开发环境(IDE)可用于编码,组装,编译和仿真。CS + 还包括入门套件。
E2 仿真器精简版 该入门级的片上调试仿真器以较低的价格提供与E1仿真器相同的功能。
E2 仿真器 该片上调试仿真器具有先进的功能,可提高开发效率。 除了从调试到闪存编程的基本功能外,还支持热插件和外部触发器作为标准项目。 该仿真器还可以通过高速下载(与E1仿真器相比)来缩短开发时间,并且可以与各种解决方案(例如,对正在开发的系统消耗的电流进行调整)结合使用。
E20 仿真器 当与RX600和RX700 MCU结合使用时,该片上调试仿真器具有增强的调试功能,例如大容量跟踪和实时RAM监视(此仿真器提供的调试功能与其他MCU的E1仿真器相同)。
E1 仿真器 该片上调试仿真器是提供基本调试功能的标准模型(于2019年12月下旬停产)。
