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.
