Renesas RX23T24V马达控制评估系统

Renesas公司的RX23T系统是内置浮点处理单元(FPU)的32位RX微控制器(MCU),工作频率40MHz,65.6DMIPS,集成了12位ADC和40MHz PWM,很容易对复杂的逆变器控制算法进行编程,从而大大地降低软件开发的人工成本和维护费用.单电源2.7-V到 5.5-V工作,主要用在通用和消费类电子设备.本文介绍了RX23T系列主要特性,框图和采用RX23T的24V马达控制评估系统主要特性和套件指标,评估系统框图,电路图,材料清单和PCB设计图.

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.

RX23T系列主要特性:

■ 32-bit RX CPU core
Max.operating frequency: 40 MHzCapable of 65.6 DMIPS in operation at 40 MHz
Enhanced DSP: 32-bit multiply-accumulate and 16-bitmultiply-subtract instructions supported..
