Renesas RX23T 32位MCU逆变器控制方案
Renesas公司的RX23T系列是32位RX MCU,工作频率40MHz,内置浮点处理单元(FPU),适合复杂的逆变器控制算法编程,40MHz时的性能为65.6 DMIPS,集成了具有三个S/H电路,两个数据寄存器和比较器的12位ADC和40MHz PWM,工作电压2.7V-5.5V,非常适合用于逆变器的控制.本文介绍了RX23T主要特性,框图,RX23T入门板RSK主要特性,布局图,元件布局图和内部连接图以及详细电路图.
The RX23T Group is 32-bit microcontroller and suited for single inverter control and has a built-in FPU (floating-point processing unit) that enables it to easily program complex inverter control algorithms. This helps to greatly reduce the man-hours required for software development and maintenance. Furthermore, thanks to the RX200 core the current consumed in software standby mode (with RAM retention) is a mere 0.45 μA. RX23T microcontrollers operate in a broad voltage range from 2.7 V to 5.5 V, which is useful for inverter control, and are highly compatible with the RX62T Group at the pin arrangement and software level.
