ATABX051

· Compatible with 40-pin MCS-51^TM sockets
· Compatible with in-circuit-emulators with 40-pin sockets
· 32 Programmable I/O Lines or 15 Programmable I/O Lines

Atmel's 20- to 40-pin adapter board is for use in designing AT89C1051/AT89C2051 systems. The ATABX051 maps the pins on the 20-pin device to the corresponding pin locations in a 40-pin 80C51 footprint. Customers can use this board to adapt existing in-circuit-emulators for use in AT89C1051/AT89C2051 designs (note that a comparator must also be added for full emulation) or to plug in 40-pin 80C51 devices into 20-pin AT89C1051/AT89C2051 sockets. In addition, the board can be used to adapt the 20-pin footprint to an existing 40-pin socket.
