Renesas公司的RX63N是100MHz 32位RX MCU ,165DMIPS性能,集成了多达2MB闪存,以太网MAC,全速USB 2.0主/功能/OTG接口,包括CAN的各种通信接口,10位和12位ADC和RTC.和现有产品相比,待机功耗降低大约90%,工作电压2.7- 3.6V,主要用在音频设备,马达控制,游戏机和通信设备.本文介绍了RX63N主要特性,方框图,RX63N开发套件应用和特性,方框图,电路图和材料清单. 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. RX63N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 500uA/MHz. RTC is capable of operation from a dedicated power supply (min. Operating voltage: 2 V). Four low-power modes On-chip main flash memory, no wait states Supports ROM-less versions and versions with up to 2 Mbytes of ROM (ROM-less version: RX631 Group only) 100-MHz operation, 10-ns read cycle (no wait states) 384-Kbyte to 2-Mbyte capacities User code programmable via the USB, SCI, or JTAG On-chip data flash memory ROM-less or 32 Kbytes of ROM (reprogrammable up to 100,000 times) Programming/erasing as background operations (BGOs) On-chip SRAM, no wait states 32- to 128-Kbyte capacities For instructions and operands Can provide backup on deep software standby DMA DMAC: Four channels DTC EXDMAC: Two channels Dedicated DMAC for the Ethernet controller: Single channel Reset and supply management Power-on reset (POR) Low voltage detection (LVD) with voltage settings Clock functions External crystal oscillator or internal PLL for operation at 4 to 16 MHz Internal 125-kHz LOCO and 50-MHz HOCO Dedicated 125-kHz LOCO for the IWDT Real-time clock Adjustment functions (30 seconds, leap year, and error) Time capture function (for capturing times in response to event-signal input on external pins) Independent watchdog timer 125-kHz LOCO clock operation Useful functions for IEC60730 compliance Oscillation-stoppage detection, frequency measurement, CRC, IWDT, selfdiagnostic function for the A/D converter, etc. Various communications interfaces Ethernet MAC (1) (not in RX631 Group products) Host/function or OTG controller (1) and function controller (1) with fullspeed USB 2.0 transfer CAN (compliant with ISO11898-1), incorporating 32 mailboxes (up to 3 modules) SCI with multiple functionalities (up to 13) Choose from among asynchronous mode, clock-synchronous mode, smartcard interface mode, simplified SPI, simplified I2C, and extended serial mode.
