NXP™ i.MX 91 ARM® Cortex™-A55

The MSC OSM-SF-IMX91 is based on the new OSM 1.1 standard (Size-S) “Small” for completely machine processible low-cost embedded computer modules during soldering, assembly and testing.

Highly scalable and equipped with i.MX 91 Applications Processors manufactured by NXP. The processor integrates an Arm Cortex-A55 core, bringing performance and energy efficiency to Linux-based edge applications and delivers advanced security with integrated EdgeLock secure enclave for cost-effective headless solutions at the edge.

MSC OSM-SF-IMX91 provides fast and low power LPDDR4 memory technology with inline ECC support, combined with up to 256GB eMMC Flash memory. Various interfaces for embedded applications such as Dual Gigabit Ethernet (RGMII), USB 2.0, 2x CAN-FD are available. The typical design power ranges from 2 W to 3 W.

The module is compliant with the new OSM 1.1 standard (OSM-SF). For evaluation and design-in of the new OSM-SF-IMX91 module, MSC provides a development platform and a starter kit. A Yocto based Linux Board Support Package is available (Android support on request).
