Renesas Electronics RX700 32位微控制器
Renesas Electronics RX700 32位微控制器是RX家族的旗舰产品。RX700 MCU具有工作频率为120MHz且容量高达4MB的闪存。这些32位MCU采用片上高级获取单元 (AFU)，即使在240MHz的最高工作频率下也能提供出色的实时性能。RX700 MCU具有32KB错误检查和纠正随机存取存储器 (ECCRAM)。这些32位MCU还具有带奇偶校验功能的512KB片上SRAM，有助于最大限度地减少因SRAM中的软件错误引起的故障。
借助RX700 MCU的硬件加密功能（如AES、DES、SHA和RNG），可以实现身份验证和数据加密，以防止数据泄露。其他安全功能包括可信存储器，这是片上闪存的一个特殊领域，包含防止未经授权读取的程序代码。
