Renesas RX62T 32位MCU开发方案

Renesas公司的RX62T是100MHz 32位RX CPU内核的MCU,在100MHz时具有165DMIPS性能,单精度32位IEEE-754浮点,累加器能从32x32位运算中处理64位结果,乘法和除法能处理32x32运算,具有快速中断功能,CPU工作电压3.3V或5V,主要用在马达控制,通用逆变器等.本文介绍了RX62T主要特性,方框图,RX62T RSK评估板主要特性,方框图,电路图和PCB元件布局图.

100-MHz 32-bit RX MCUs, FPU, 165 DMIPS, 12-bit ADC (3 S/H circuits, double data register, amplifier, comparator): two units, 10-bit ADC one unit, the three ADC units are capable of simultaneous 7-ch. sampling, 100-MHz PWM (two three-phase complementary channels and four single-phase complementary channels or three three-phase.

RX62T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

 Accumulator handles 64-bit results (for a single instruction) from 32- × 32-bit operations

 Multiplication and division unit handles 32- × 32-bit operations (multiplication instructions take one CPU clock cycle)

 Fast interrupt

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

 Fast interrupt
