| VersaLogic SPX™ Modules
A new level of economy and convenience for routine
I/O expansion
VersaLogic’s SPX expansion modules provide
a new level of economy and convenience for routine I/O expansion.
Their small size, low cost, and simplified system interface is possible
due to high levels of integration and miniaturization that was not
available previously.
Unlike larger expansion formats such as PC/104, the
extremely compact SPX format does not require a stacking connector
or a position in the expansion stack. Connected by a single 14-pin
cable to any SPX-enabled base board, SPX expansion modules can be
mounted in any position, up to two feet from the host. The small (1.2”
x 3.8”) SPX modules may optionally be attached to the base board
using PC/104 stand-offs.
- Small Footprint - 1.2” x 3.8” size is ideal for space-constrained applications
- Industrial Temperature - All SPX™ modules designed for -40º to 85ºC operation
- Multiple I/O Expansion - Up to four SPX modules can be used in each system
- Ease of Use - Simple cable-based interface
- Flexibility - Mount on expansion stack, or up to two feet away
- Custom I/O Functions - Custom I/O solutions are quick to develop
- RoHS-compliant - Standard modules are fully compliant

Up to four SPX modules can be daisy-chained together
to meet targeted I/O requirements at a substantial cost and space
savings. Typical functions available include:
- 8-channel Analog Input
- 16-bit Digital I/O
- 4-channel Analog Output
- CANbus Controller
- 8-channel Solid State Switch
SPX modules can be used with baseboards (single board computers)
that include an SPX expansion connector. This includes products such
as VersaLogic’s Python and Sidewinder SBCs. SPX modules can
also be used with other systems that include an SPI signaling interface.
Custom cabling and signaling restrictions may apply when connecting
to generic SPI signals.
All VersaLogic SPX modules are fully RoHS-compliant, and are backed
by VersaLogic’s standard two-year limited warranty. All SPX
modules are rated for extended temperature operation (-40º to
85ºC).
Like all VersaLogic products, SPX I/O modules are designed to support
OEM applications where high reliability and long-term availability
are essential. From ease of application design-in to a five year availability
guarantee, their quality and longevity provide low-cost, long-term
solutions for demanding applications. SPX modules are manufactured
to the highest quality standards.
In addition to standard off-the-shelf modules, VersaLogic can design
custom SPX modules.
SPX Details
The SPX platform uses SPI signaling with a defined
interconnect using a 14-pin 2 mm cable. This allows a single chip
interface between the I/O device and the SPX interface. The simplified
system interface means that custom I/O functions are inexpensive and
straightforward to implement.
Multiple SPX modules, up to four per system, can
be used at once. Modules of the same or different I/O type can be
daisy-chained together using a single cable with multiple connectors.
The modules are connected to the baseboard via a 14-pin cable.
External I/O signals are typically connected directly
to SPX modules via the on-board screw terminals. The 14-pin SPX interface
cable typically provides up to 500mA of fused +5V power for use by
the connected modules.
