Renesas RX65N MCU入门开发方案

Renesas公司的RX65N是采用32位RXv2 CPU核的高性能MCU,最大工作频率120MHz,在120MHz时的性能240DMIOS,单精度32位IEEE-754浮点,嵌入了90nm和40nm快速存储器,在核处理,代码效率和功耗上具有极好的性能,片上还集成了混合信号外设,工作电压2.7到3.6-V,主要用在物联网连接和马达控制等.本文介绍了RX65N主要特性,框图,以及RX65N入门开发板(RSK)主要特性和指标,框图,元件布局图,电路图和材料清单.
RX65N, RX651 group are highly compatible among the same series both in functional scalability and pin assignments.
In addition, driver/middleware (FIT support) and sample code-generation tools (code generators) and evaluation boards　(starter kits) to allow reuse of most of developed hardware/software resources, enabling seamless and scalable product development from small to large scale applications without effort in a short-time.
RX65N主要特性:

■ 32-bit RXv2 CPU core
 Max. operating frequency: 120 MHz
Capable of 240 DMIPS in operation at 120 MHz
 Single precision 32-bit IEEE-754 floating point
 Two types of multiply-and-accumulation unit (between memoriesand between registers)
 32-bit multiplier (fastest instruction execution takes one CPU clockcycle)
 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 (one-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 peripheralfunctions draws only 0.19 mA/MHz (Typ.).
 RTC is capable of operation from a dedicated power supply.
 Four low-power modes
■ On-chip code flash memory
 Supports versions with up to 1 Mbytes of ROM
 No wait cycles at up to 50 MHz ...
