Easy8051 v6 Development System
2.0. Supported Microcontrollers
The Easy8051 v6 development system provides eight separate sockets for 8051 microcontrollers in DIP40, DIP28, DIP20, DIP16,
DIP14A, DIP14B, PLCC44 and PLCC32 packages. These sockets allow supported microcontrollers in DIP packages to be directly
plugged into the development board.
8051 microcontrollers can use either internal (on-board) or external oscillator for the generation of the clock signals. There is a quartz
oscillator used as an external oscillator provided on the board. Signals generated by such an oscillator are used as clock signals for
most supported microcontrollers.
Prior to plugging a microcontroller into the appropriate socket, make sure that the power supply is turned off. It is shown in Figure 2-2
how to correctly plug in a microcontroller. Figure 1 shows an unoccupied DIP40 socket. Place one end of the microcontroller into the
socket as shown in Figure 2. Then put the microcontroller slowly down until all the pins thereof match the socket as shown in Figure
3. Check again that everything is placed correctly and press the microcontroller down easily until it is completely plugged into the
socket, as shown in Figure 4.

There are two sockets for 8051 microcontrollers in DIP14 package
provided on the board. Which of these sockets will you use
depends solely on the pinout of the microcontroller in use. The
Easy8051 v6 development system comes with the microcontroller
in DIP40 package.
Jumpers J7, J8 and J16 next to the DIP40 socket and oscillator
are used for selecting functions of the microcontroller pins.
