Applications processors expand Linux capabilities

Extending its i.MX 9 portfolio, NXP Semiconductors has introduced its new family of i.MX 91 applications processors that enable developers to build Linux-based edge devices with an optimized mix of energy-efficient performance, security and Linux capabilities.

NXP said emerging protocols such as Matter for the smart home, or the ISO 15118-20 standard for electric vehicle (EV) chargers, create a turning point for new product categories for IoT and industrial applications that rely on Linux for ease of programming. These edge devices include home controllers, connected appliances, home entertainment, industrial scanning and printing, building control, EV chargers and medical platforms.

The i.MX 91 applications processors feature an Arm Cortex-A55 running at up to 1.4 GHz, LPDDR4 memory support for platform longevity and reliability, dual Gigabit Ethernet for gateway or multi-network segment support, dual USB ports and essential I/O. In addition, hardware and software commonality with the NXP i.MX 93 family provides more platform options for scaling product lines.

Security features include an integrated EdgeLock secure enclave security subsystem that provides advanced security features, such as lifecycle management, tamper detection, secure boot and a simplified path to certifications. The security capabilities are accessed by the developers through NXP-provided security software enablement.

The i.MX 91 family is available with NXP’s co-developed and power management solution, available as part of the i.MX 93 family ecosystem. The evaluation kits and software packages for the i.MX 91 family integrate with NXP’s portfolio of wireless solutions. This includes the IW612, a monolithic tri-radio family that supports Wi-Fi 6, Bluetooth 5.2 and 802.15.4.

The i.MX 91 development platforms will be available to select customers in the second half of 2023 as part of the early access program. It is supported by an ecosystem of tools and software. Availability is guaranteed for a minimum of 15 years as members of the NXP product longevity program.
