The DEC i.MX 91 computing module delivers reliable performance, low power consumption, and secure connectivity in a compact, industry-standard OSM form factor. Built using the NXP i.MX 91 processor, it provides an ideal foundation for embedded systems that require consistent performance, long-term availability, and a clear path forward to next-generation designs.
Driven by an Arm® Cortex®-A55 core running up to 1.4 GHz and integrated Arm® Cortex®-M33 co-processor, the DEC i.MX 91 computing module supports efficient Linux-based processing with dependable real-time control. It offers a rich set of interfaces, including Ethernet, USB, UART, SPI, and I²C to enable seamless integration into industrial, commercial, and IoT applications.
The DEC i.MX 91 computing module’s OSM form factor gives designers a straightforward upgrade path to higher performance and on-device AI capabilities when needed—without changing their carrier design. This continuity allows OEMs to scale products easily while maintaining a consistent hardware and software foundation.
Designed, engineered, and supported in the U.S., DTI’s i.MX 91 Computing Module combines long-term availability with nationwide technical support, helping developers build connected, cost-effective embedded products that last.
