NXP’s New, Secure, Energy-Efficient i.MX 91 Family Expands Linux Capabilities for Thousands of Edge Applications

The newest member of the i.MX 9 series streamlines the development of cost-optimized edge devices that require security, performance, and Linux support in a scalable, reliable platform

What’s new: NXP Semiconductors today announced the i.MX 91 applications processor family. Building on more than two decades of leadership in developing multi-market applications processors, the i.MX 91 family delivers an optimized blend of the security, features, and energy-efficient performance required for the next generation of Linux®-based IoT and industrial applications.

Why it matters: Emerging protocols such as Matter, the interoperable, secure connectivity standard for the future of the smart home, or the ISO 15118-20 standard for electric vehicle (EV) chargers, create inflection points for new product categories across IoT and industrial markets. These new products often rely on Linux, which provides the extensibility and ease of programming developers need for applications to evolve, extending product life. NXP’s i.MX 91 family enables developers to quickly create new Linux-based edge devices, such as home controllers, connected appliances, home entertainment, industrial scanning and printing, building control, EV chargers and medical platforms.

“The i.MX 91 family extends NXP’s leadership in smart controllers,” said Jim McGregor, Principal Analyst at TIRIAS Research. “Next-generation Linux devices based on the i.MX 91 applications processors will be high-performance, affordable, and secure solutions, enabling quicker and easier adoption of updated protocols or new standards as they are introduced. It provides engineers with an essential platform to add intelligence into traditional embedded and IoT systems, while also delivering scalability through the larger i.MX 9 series.”

As the entry point of the i.MX 9 series, the i.MX 91 family provides the extensibility and ease of programming that developers need for applications to evolve over time. Hardware and software commonality with the NXP i.MX 93 family provides additional platform options for scaling product lines that maximize re-use of development investments and decreases time to market.

More details: “Our new i.MX 91 family will provide the foundation for thousands of new device classes, with its high performance, connectivity and EdgeLock secure enclave setting a new standard for Linux platforms across IoT and industrial applications,” said Charles Dachs, Senior Vice President and General Manager, Industrial and IoT Edge, at NXP. “The i.MX 91 family enables the rapid development of platforms that may easily pivot into new markets and new applications, leveraging existing investments and streamlining product line updates.”

The i.MX 91 applications processor features an Arm® Cortex®-A55 running at up to 1.4 GHz; support for modern LPDDR4 memory to enable platform longevity and reliability; dual Gigabit Ethernet for gateway or multi-network segment support; dual USB ports; and the essential I/O for products in smart factory, smart home, smart office, medical device, metering, and cost-optimized system-on-module platforms.

An integrated EdgeLock secure enclave provides advanced security features, such as lifecycle management, tamper detection, secure boot, and a simplified path to certifications. These important security capabilities are easily accessed by the developers through NXP-provided security software enablement. This combination of security and manageability drives trust and longevity for platform designs that will be in the market for many years.

The i.MX 91 family is available with NXP’s co-developed and cost-optimized 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 broad, scalable portfolio of wireless solutions. This includes the IW612, the industry’s first monolithic tri-radio family that supports Wi-Fi 6, Bluetooth® 5.2 and 802.15.4. The IW612, focused on Matter, frees consumers from the restrictions of single-protocol ecosystems, allowing them to enjoy seamless interoperability across different ecosystems and wireless network technologies.

NXP’s i.MX applications processors are available worldwide through distributors and eTailers. They are enabled by NXP software, a broad ecosystem of tools and software, and comprehensive support. To help ensure a stable supply of products for embedded designs, all i.MX 8 series and i.MX 9 series products are guaranteed for a minimum of 15 years of availability as members of the NXP product longevity program.

NXP expects to enable select customers with i.MX 91 development platforms in 2H23 as part of the early access program. For more information, visit
