Renesas RX630系列32位MCU开发方案

Renesas公司的RX630系列是32位MCU,工作频率最大为100MHz,100MHz时的性能为165 DMIPS,具有单精度32位IEEE-754浮点,两种类型的乘法和累加器,工作电压2.7V-3.6V,主要用在嵌入式系统.本文介绍了RX630系列主要特性,方框图,RX630系列评估板主要特性与指标,方框图,电路图和元件布局图.
 
RX630系列主要特性:

■ 32-bit RX CPU core

 Max. operating frequency: 100 MHz

Capable of 165 DMIPS in operation at 100 MHz

 Single precision 32-bit IEEE-754 floating point

 Two types of multiply-and-accumulation unit (between memories and between registers)

 32-bit multiplier (fastest instruction execution takes one CPU clock cycle)

 Divider (fastest instruction execution takes two CPU clock cycles)

 Fast interrupt

 CISC Harvard architecture with 5-stage pipeline

 Variable-length instructions: Ultra-compact code

 Supports the memory protection unit (MPU)

 JTAG and FINE (two-line) debugging interfaces

■ Low-power design and architecture

 Operation from a single 2.7- to 3.6-V supply

 Low power consumption: A product that supports all peripheral functions draws only 500 μA/MHz.
