SPX EXPANSION MODULES Simplified I/O Expansion Cost effective I/O expansion Bolts to PC/104 stack (optional) Off-the-shelf and custom modules available Highlights Overview Small Footprint VersaLogics SPX expansion modules provide a new level of economy and convenience for 1.2 x 3.8 size is ideal for space-constrained applications. routine I/O expansion. Their small size, low cost, and simplified system interface are possible due to high levels of integration and miniaturization that were not previously available. Industrial Temperature All SPX modules designed for -40 to 85C operation. 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 Multiple I/O Expansion Up to four SPX modules can be used in each system. 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 Ease of Use attached to the base board using PC/104 stand-offs. Simple cable-based interface. Up to four SPX modules can be daisy-chained together to meet targeted I/O requirements at Flexibility Mount on expansion stack, or up to two feet away. a substantial cost and space savings. Typical functions available include: Custom I/O Functions 8-channel Analog Input Custom I/O solutions are quick to develop. 16-bit Digital I/O 4-channel Analog Output RoHS-compliant CANbus Controller Standard modules are fully compliant. 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 VersaLogics 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 VersaLogics Ordering Information standard two-year limited warranty. All SPX modules are rated for extended temperature operation (-40 to 85C).

This allows a single chip interface between the I/O device and the 500 KSPS SPX interface. The simplified system interface means that custom I/O functions 16-bit Digital I/O Module SPX-2 are inexpensive and straightforward to implement. 3.3V CMOS Interface Bit programmable Multiple SPX modules, up to four per system, can be used at once. Modules IRQ generation of the same or different I/O type can be daisy-chained together using a single CANbus Controller SPX-3 cable with multiple connectors. The modules are connected to the baseboard CAN V2.0B 1 Mb/s Receive buffers, masks and filters via a 14-pin cable. 4-channel Analog Output Module SPX-4 External I/O signals are typically connected directly to SPX modules via the on- 12-bit resolution, 5s settling time board screw terminals. The 14-pin SPX interface cable typically provides up to 10mA per channel output current 0 to +4.095V (1 mV per bit) 500mA of fused +5V power for use by the connected modules. 8-channel Solid State Switch Module SPX-5 Custom modules for most functions are very easy to develop on the SPX platform.
