 MCBx51 Evaluation Board

    The Keil MCBx51 Evaluation Board introduces the 8051 and 251 microcontroller families. It works with all 44-pin 8051 and 251 devices including the Intel 251Sx/Tx; Atmel T80C251G1D/G2D and 8051Rx2; Philips 8051Rx2 and 8xC664; and Dallas 320, 420, and 520.

    The Keil MCBx51 single-board computer is an evaluation board that supports numerous 8051-compatible and 251-compatible devices. The MCBx51 allows you to investigate the capabilities of the 8051 and 251 and create real working programs with the Keil development tools. The MCBx51 works with any 44-pin 8051-compatible or 251-compatible device.
