INTEL® IXP42x MODULES

Viking Modular Solutions’ family of Intel® IXP42x based modules provide system designers with off-the-shelf cost-effective high-performance network processor based computer-on-module solutions that drastically reduce the time-to-market of their designs. Since the Intel IXP42x based modules include an IXP42x processor, associated 133 MHz SDRAM memory, and NOR Flash storage, all that is needed to complete the design is a customized baseboard providing physical connectors.
The Intel IXP42x module’s soldered down SDRAM and flash components make it ideal for ruggedized applications. The module connects to the customized baseboard using a standard JEDEC SODIMM connector typically used in laptop systems that are inexpensive and readily available. The module’s small credit card size (50.00mm x 67.60mm) makes it ideal for applications requiring a portable solution.
Since all Intel IXP42x based modules use the same 200-pin edge connector signal assignments, they can be interchanged by the designer to support the need for additional memory capacity or processor speed. This enables designers to design a single baseboard that can be used for multiple product offerings.
The IXP42x module supports all versions of the Intel IXP42x processor family. The following table describes the hardware and software features supported by the IXP42x module based on the Intel IXP42x processor selected:
