MCU sockets
As previously mentioned, the EasyPIC v8 development board supports all 8-bit PIC
MCUs in DIP package type. There are eight diff erent sockets, ranging from DIP8 (8-pin
DIP socket), up to DIP40 (40-pin DIP socket). All DIP sockets are grouped in the lower
left area of the board (1).
Only a single DIP socket should be populated at a time since their lines are shared.
Each DIP socket allows an MCU with the specifi c pin-count to be used. For example, if
using a 40-pin MCU, it should be placed into the DIP40 socket, exclusively (i.e. placing
an 8-pin MCU into the DIP14 socket will cause pin misalignment and other problems).
However, there are exceptions to this rule: if using an MCU in DIP18 package type,
there are two options available, depending on its pinout: DIP18A and DIP18B. To
determine the correct socket that should be used in this case, the pinout of the MCU
should be compared with the pinout which is printed next to these sockets.
A similar exception applies to the DIP8 socket: if using an 8-pin MCU from PIC10F
MCU families, it should be installed in the 10F MCU socket instead of the DIP8 socket.
How to install the MCU into the DIP socket?
First make sure that a half circular cut in the microcontroller DIP packaging matches
the cut in the DIP socket (2). Align both ends of the microcontroller with the socket.
Then put the microcontroller slowly down until all the pins match the socket. Check
again if everything is placed correctly and gently press the microcontroller until it is
completely plugged into the socket.
