Abstract
A programmable device I/O architecture allows for a variable number of I/O banks. Each I/O bank is of an I/O bank type. Each I/O bank type has a fixed number of I/O pins. I/O banks of the same I/O bank type are compatible within the same programmable device and between different types of programmable devices. The largest size I/O bank type and intermediate size I/O bank types are adapted to be a compatible supersets of every smaller I/O bank type. Support pins are regularly distributed between data pins in each I/O bank type. Multiple instances of the same or compatible I/O banks are arranged to be accessible from different sides of the programmable device. To facilitate circuit board layout, each I/O bank is arranged as a mirror and/or rotation of other I/O banks on the device.
