XScale-PIO-64
The XScale-PIO-64 stackable I/O module provides (64) sixty-four independent parallel I/O lines on a single module. This module plugs directly into the back of the XScale-Mini, XScale-Maxi, XScale-5.7, XScale-Magnum, and XScale-Extreme Embedded Single Board Computers. Each line is TTL compatible, open collector with pull-ups on-board, and can be independently used for either input or output. The XScale-PIO-64 also provides (4) four TTL compatibly interrupt inputs. The XScale-PIO-64 can be stacked along with any other XScale I/O module of your choice, including another XScale-PIO-64.
