Renesas公司的RX63N是100MHz 32位RX MCU ,165DMIPS性能,集成了多達2MB閃存,以太網MAC,全速USB 2.0主/功能/OTG接口,包括CAN的各種通信接口,10位和12位ADC和RTC.和現有產品相比,待機功耗降低大約90%,工作電壓2.7- 3.6V,主要用在音頻設備,馬達控制,游戲機和通信設備.本文介紹了RX63N主要特性,方框圖,RX63N開發套件應用和特性,方框圖,電路圖和材料清單.

The RX63N/RX631 Group incorporates communication functions suitable for networking equipment, such as Ethernet controller, USB 2.0 full-speed (function, host, or OTG selectable), and CAN. In addition, with a RTC (Real-Time Clock) that can operate on a dedicated power supply as a low power feature, standby power consumption can be reduced by approximately 90% compared to existing products. The selection of on-chip memory has been expanded from ROMless to 2 MB, and even smaller-sized packages are available. This makes possible mounting in anything from large-scale systems to small-scale/small-space devices.
