STC12C5A60S2系列1T单片机简介 STC12C5A60S2/AD/PWM系列单片机是宏晶科技生产的单时钟/机器周期(1T)的单片机，是高速/低功耗/超强抗干扰的新一代8051单片机，指令代码完全兼容传统8051,但速度快8-12倍。内部集成MAX810专用复位电路,2路PWM,8路高速10位A/D转换(250K/S),针对电机控制，强干扰场合。 1.增强型8051 CPU，1T，单时钟/机器周期，指令代码完全兼容传统8051 2.工作电压：STC12C5A60S2系列工作电压：5.5V- 3.3V(5V单片机)STC12LE5A60S2系列工作电压：3.6V- 2.2V(3V单片机) 3.工作频率范围：0 - 35MHz，相当于普通8051的0～420MHz 4.用户应用程序空间8K /16K / 20K / 32K / 40K / 48K / 52K / 60K / 62K字节...... 5.片上集成1280字节RAM 6.通用I/O口(36/40/44个)，复位后为：准双向口/弱上拉(普通8051传统I/O口) 可设置成四种模式：准双向口/弱上拉，推挽/强上拉，仅为输入/高阻，开漏每个I/O口驱动能力均可达到20mA，但整个芯片最大不要超过55mA 7. 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(P3.0/P3.1)直接下载用户程序，数秒即可完成一片 8.有EEPROM功能(STC12C5A62S2/AD/PWM无内部EEPROM) 9. 看门狗

10.内部集成MAX810专用复位电路(外部晶体12M以下时，复位脚可直接1K电阻到地) 11.外部掉电检测电路:在P4.6口有一个低压门槛比较器5V单片机为1.32V，误差为+/-5%,3.3V单片机为1.30V，误差为+/-3% 12.时钟源：外部高精度晶体/时钟，内部R/C振荡器(温漂为+/-5%到+/-10%以内) 1用户在下载用户程序时，可选择是使用内部R/C振荡器还是外部晶体/时钟常温下内部R/C振荡器频率为：5.0V单片机为：11MHz～15.5MHz 3.3V单片机为：8MHz～12MHz 精度要求不高时，可选择使用内部时钟，但因为有制造误差和温漂，以实际测试为准 13.共4个16位定时器两个与传统8051兼容的定时器/计数器,16位定时器T0和T1，没有定时器2，但有独立波特率发生器做串行通讯的波特率发生器再加上2路PCA模块可再实现2个16位定时器 14. 2个时钟输出口，可由T0的溢出在P3.4/T0输出时钟，可由T1的溢出在P3.5/T1输出时钟 15.外部中断I/O口7路,传统的下降沿中断或低电平触发中断,并新增支持上升沿中断的PCA模块，Power Down模式可由外部中断唤醒，INT0/P3.2, INT1/P3.3, T0/P3.4, T1/P3.5, RxD/P3.0, CCP0/P1.3(也可通过寄存器设置到P4.2 ), CCP1/P1.4 (也可通过寄存器设置到P4.3) 16. PWM(2路)/PCA(可编程计数器阵列,2路) ---也可用来当2路D/A使用---也可用来再实现2个定时器---也可用来再实现2个外部中断(上升沿中断/下降沿中断均可分别或同时支持) 17.A/D转换, 10位精度ADC，共8路，转换速度可达250K/S(每秒钟25万次) 18.通用全双工异步串行口(UART)，由于STC12系列是高速的8051，可再用定时器或PCA软件实现多串口 19. STC12C5A60S2系列有双串口，后缀有S2标志的才有双串口，RxD2/P1.2(可通过寄存器设置到P4.2)，TxD2/P1.3(可通过寄存器设置到P4.3) 20.工作温度范围：-40 - +85℃(工业级) / 0 - 75℃(商业级)21.封装：PDIP-40,LQFP-44,LQFP-48 I/O口不够时，可用2到3根普通I/O口线外接74HC164/165/595(均可级联)来扩展I/O口, 还可用A/D做按键扫描来节省I/O口，或用双CPU,三线通信，还多了串口。
