Using this programmer you can program the internal flash of the microcontroller AT89C2051 from Atmel. The AT89C2051 programmer is connected via the serial RS232 interface to a PC. In comparison with other programmers, you do not need a special software, a terminal program is sufficient. So there are no platform dependent limitations and it can be used universally.



Generally the programmer supports two different modes:

1. User mode: The desired operation Program (including Erase), Verify, Read or Lockbits can be selected via a BCD switch and started by pressing a button. The desired programming data will be transmitted or received in binary format via the RS232 interface. A special software data handshake is not required. A LED shows the current status.
