美国SST 89系列单片机的高可靠性,独特的超级FLASH技术和小扇区结构在设计和制造MCU方面有较大的优势,3V/5V在应用可编程(IAP),在系统可编程(ISP),不占用户资源,无需改动硬件(增加无用的所谓下载开关,12V编程电源)。通过串口在系统仿真,无需专用仿真器,生产用单片机就是仿真CPU,低价格,教学用首选单片机,代表着单片机SOC的发展方向。 大容量内部数据RAM:1K字节RAM,C语言编程更方便,RTOS应用更容易 双DPTR数据指针,查表、寻址更方便
The high reliability of the SST 89 family of microcontrollers in the United States, the unique super FLASH technology, and the small sector structure provide significant advantages in designing and manufacturing MCUs. The 3V / 5V devices are widely used in application programmable (IAP), system programmable (ISP) , Do not account for user resources, without changing the hardware (increase useless so-called download switch, 12V programming power). Through the serial port in the system simulation, no special simulator, the production of single-chip microcomputer is the simulation of CPU, low price, teaching the preferred microcontroller, representing the development of single-chip SOC. High-capacity internal data RAM: 1K bytes RAM, C language programming more convenient, RTOS easier to use dual DPTR data pointer, look-up table, addressing more convenient
