NXP™ i.MX 91 Arm® Cortex™-A55

The MSC SM2S-IMX91 SMARC 2.1.1 module family is highly efficient 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.

The MSC SM2S-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, USB 2.0 and CAN-FD are available. An on-board Wireless Module is provided as assembly options. The typical design power ranges from 2 W to 3 W.

The module is compliant with the new SMARC 2.1.1 standard, allowing easy integration with SMARC baseboards. For evaluation and design-in of the SM2S-IMX91 module, Avnet Embedded provides a development platform and a starter kit. Support for Linux is available (Android support available on request).
