The 80c196kc family's on-chip peripheral set includes a Pulse Width Modulator (PWM) for generating a pulse train of varying width, which can be filtered to generate analog voltages. This can be used to generate sine waves and even more complex waveforms by periodically changing the PWM value.

Note that different members of the 8096 family may have 1, 2, or 3 PWM generators, and may implement them in different manners. This application note is specific to the PWM generator in the 8096 and 80C196KC/KD families of parts, not the HSI/O module's PWM mode, or the PWM generator of the 80C196MC, although similar applications may be possible with these parts.

3) How to assemble the 80196kit

1. Check the components with the list.
2. Devide the main board and the communication board.

.  ---->    


3. Put the IC socket into then solder it. Remain the 64pin PLCC socket for the last soldering.
   
The IC socket which has a groove on top should head to No. IC1 side.
 Put the 27C256 into on top of the 62256 by the round socket. Make the the middle of the 80c196 socket then solder it.

   

      

          

참고:  64핀 PLCC 타입은 중앙에 있는 부분을 위에 있는 사진과 같이 홈을 만든 다음에 소켓을 끼우고
납땜을 수행하면 될 것이다. 중앙에 콘덴서와 크리스탈을 납땜하기 위해서 하는 작업임을 명심하자.

4. Solder the Christal(Y1) / 20pF ceramic condenser 2EA / Condenser / 104 Condenser in the middle of the
   80c196 socket.  Solder the 4.7K resistor 3EA/ 104 Condenser/ 10uF Electrolytic condenser. 

Caution) 10uF electrolytic condenser has the polarity, the long lead and black side is (+).

.
Solder the 3 switches(Push SW S1, S2, S3)
    Solder the JP1 / J5

  104 Solder the condenser 3EA / Header pin female.

         

6. solder header pin male(J2: for LCD ), header pin female(JP1, Serial port J5 board).

            

               

5. Solder header pin female(J1, J3, J4). it is extension port.

           

                                  

               /* Solder header pin male(J1, J3, J4) as shown in fig  */

Put the IC from the 62256. Put the 2 jumpers into the JP1 vertically.

6. Put the IC socket U4 for 61256 RAM.  put the U1(80c196kc), U2(74HC573), U4( 27C256 ROM),
   U5(16V8).  put the jumper socket in the JP1 header pin .
  
      


7. Making the communication board(Max232)

 (solder the header pin female J6, IC socket U6,  connector maleJ7, J8 and condencer 22uF 4EA)

      



8. connect the communication board  with 80c196kc main board

                   


9. Make a
communication cable.

  

  

    
** 9 pin connector : No2 pin(Red), No3 pin(White), No5 pin(Black).

10.
Put the power into. Be careful the direction. If the polarity is changed, the board will be out of order.
  You should check the memory at the communication situation and download one file for make sure
