Taiwan FEELING series are general-purpose eight-bit microcontroller family of microcontrollers, which with the EMC / PIC / MDT series of the same type of MCU with PIN-TO-PIN-compatible relations can direct substitution. And it is more concise set of instructions to use, the internal integration of the strengthening of functions, and thus good performance, better price, the main features: 

 Instruction more efficiently, and programming more convenient; 
 Chip oscillator mode more, meet various requirements; 
 The number of clock cycles have three choices: 2 or 4 or 8, is conducive to the improvement of anti-interference performance; 
 Internal detection / reset circuit design more and more reliable; 
 I / O port PULL HIGH / PULL DOWN / OPEN DRAIN more complete; 
 RAM slightly increased; 
 More useful integrated features (different sub-chips, such as: RFC / PWM); 
 Compatibility with well-designed, you can even use other companies developing similar products for development tools, without more investment and learning (although this can not be fully play its special features).
