DIF series 8-bit microcontroller is a flash built-in EEPRM microcontroller with RISC structure. It has the characteristics of high speed, low power consumption, good anti-interference performance, easy to learn and use. For the applications that need repeated programming and power down memory, the programming life of more than 100000 times, the erasure performance of EEPROM of 1 million times and the storage time of up to 10 years can meet the application requirements of different occasions.
