CardBus / Digital Bus Interface

The Pico E-15 can run as a standalone product or be connected to a host using the CardBus connector. By default, the Pico E-15 ships with firmware that is ready for use as a CardBus device.

The CardBus interface is a subset of PCI. The data path is 32 bits wide and is synchronous. The wiring of the CardBus interface supports both completion and mastering of the bus.

When the Pico E-15 is not connected to a CardBus host, the digital bus can be reconfigured to connect with a wide variety of high speed digital busses and peripherals. With proper external termination, speeds of over 100 MHz are possible. The external digital bus can only interface with 3.3V logic.

Those who are interested in alternate interfaces should contact Pico Computing. The CardBus interface source code and support is available.
