The CPU-161-29 is the latest product in Dynatem’s COM Express module product line based on Freescale’s QorIQ processor family. The CPU-161-29 is fitted with the dual core P2020 processor and has ECC support. The CPU-161-29 is a versatile product suited for several markets including medical, transportation, and communications.

The CPU-161-29 comes with extensive I/O by coupling the capabilities of the QorIQ processor with our engineering expertise and focus on small footprint and high-end performance. These features include three Gigabit Ethernet ports, dual UARTS, and quad USB 2.0 ports. The CPU-161-29 also allows for graphics and video plug-ins with VGA and LVDS features.

OEMs can choose from a Linux or VxWorks operating system, taking advantage of these development environments.

Dynatem offers a standard carrier board and services for those customers who wish to design their own.
