STC89C55RD+

STC89系列单片机; • 增强型8051单片机，6时钟/机器周期和12时钟/机器周期可任意选择，指令代码完全兼容传统8051\r\n• 工作电压：5.5V - 3.3V (5V单片机) / 3.8V - 2.0V (3V单片机)\r\n• 工作频率范围：0～40MHz，相当于普通8051的 0～80MHz，实际工作频率可达48MHz.\r\n• 用户应用程序空间：4K / 8K / 13K / 16K / 32K / 64K字节\r\n• 片上集成1280字节或512字节RAM\r\n• 通用I/O口(35/39个)，复位后为：P1/P2/P3/P4是准双向口/弱上拉(普通8051传统I/O口)；P0口是开漏输出，作为总线扩展用时，不用加上拉电阻，作为I/O口用时，需加上拉电阻。\r\n• ISP（在系统可编程）/ IAP（在应用可编程），无需专用编程器，无需专用仿真器 可通过串口（RxD/P3.0, TxD/P3.1）直接下载用户程序，数秒即可完成一片\r\n• 有EEPROM功能\r\n• 看门狗\r\n• 内部集成MAX810专用复位电路(HD版本和90C版本才有),外部晶体20M以下时，可省外部复位电路。\r\n• 共3个16位定时器/计数器，其中定时器0还可以当成2个8位定时器使用。\r\n• 外部中断4路,下降沿中断或低电平触发中断，PowerDown模式可由外部中断低电平触发中断方式唤醒。\r\n• 通用异步串行口(UART)，还可用定时器软件实现多个UART\r\n• 工作温度范围：-40 ~ +85℃(工业级) / 0 ~ 75℃(商业级)\r\n• 封装：LQFP-44,PDIP-40,PLCC-44,PQFP-44.;
