Software Expertise: Reference & Software Expertise




A member of VersaLogics family of SPX expansion modules, the VL-SPX-4 provides a new level of economy and convenience to expand the capabilities of embedded computing systems. Unlike typical larger expansion formats, the SPX format does not require a stacking connector or a position in the expansion stack. Utilizing a single 14-pin cable, SPX expansion modules can be freely mounted, up to two feet from an SPX-enabled baseboard. This is particularly useful in highly compact areas or high-noise environments common in industrial, automotive, and medical applications. The small (1.2 x 3.8) SPX modules can also be attached to the baseboard using standoffs. Up to four SPX modules can be daisy-chained together to meet specifically targeted I/O requirements, resulting in substantial cost and space savings for developers.

Like all VersaLogic products, the VL-SPX-4 is designed to support rugged OEM applications where high reliability and long-term availability are required. From application design-in to 5+ guaranteed years of production life, the VL-SPX-4 provides a durable expansion solution with an excellent cost of ownership. The VL-SPX-4 is manufactured and tested to the highest quality standards and is fully RoHS compliant. Customization is available, even in low OEM quantities.


  • 12-bit resolution
  • 5 s settling time
  • 10 mA per channel output current
  • 0 to +4.095V (1 mV per bit)
