NXP Semiconductors has introduced the i.MX 94 family, the newest addition to its i.MX 9 series of applications processors. Specifically, the new addition targets industrial control, programmable logic controllers (PLCs), and telematics. Moreover, they also suit industrial and automotive gateways, as well as building and energy control.

Secure, real-time communication is essential for both industrial and automotive applications.
Meanwhile, increasingly complex industrial environments rely on a wide variety of communication protocols. Thus, requiring an intelligent TSN switch to manage real-time communication and control needs.

In the automotive industry, the accelerating shift towards software-defined vehicles means that underlying vehicle architectures increasingly rely on Ethernet-based communications. Thus, by integrating communications, safety, and real-time control features into a single SoC, the i.MX 94 family helps designers navigate this growing complexity. Therefore, ensuring optimized end-to-end performance when coordinating real-time communication and actions.

The integrated 2.5 Gbps Ethernet TSN switch enables highly configurable, secure communications with rich protocol support for both industrial and automotive applications.
“Connectivity is more complex than ever before, and the i.MX 94 family is designed to help simplify that complexity,” said Charles Dachs, Senior Vice President and General Manager, Industrial and IoT, NXP. “The i.MX 94 family delivers the high-performance edge processing needed for today’s industrial automation, as well as automotive telematics applications, with the advanced networking, security, safety, and AI capabilities needed to enable tomorrow’s innovations.”

Multi-Core Design Delivers High Performance, Low Latency Intelligent Edge Processing

The multi-core i.MX 94 family of 64-bit applications processors features up to four Arm® Cortex®-A55 cores capable of running Linux, along with two Cortex-M33 cores and two Cortex-M7 cores to offer increased real-time processing capability.

NXP’s Real-Time Edge software framework enables developers to realize designs with an optimal combination of real-time and application-level tasks. Specifically, running across any of these cores.
In addition, a variety of third-party purpose-built commercial operating systems such as QNX Neutrino and Green Hills Integrity are available to harness the compute capabilities. Moreover, it also features an integrated functional safety island, along with configurable safety partition, to support IEC61508 SIL2 and ISO26262 ASIL-B compliance.

Purpose-Built for Complex Networking Environments

The i.MX 94 family includes the first i.MX applications processor to integrate a 2.5Gbps Ethernet TSN switch. Most importantly, featuring fast initialization and support for low power modes.

NXP’s real-time edge software supports a wide variety of industrial protocols from legacy implementations to the latest developments. Among them are OPC-UA FX and OPC-UA PubSub.
With hardware support for network virtualization, the i.MX 94 family supports software-defined networking. This is essential to enabling complex, multicore use-cases based on open standards such as XDP and DPDK.

The i.MX 94 family supports traditional serial fieldbus protocols such as Profibus, Modbus, CANopen and IO-Link, as well as Ethernet-based real-time networking protocols, such as Profinet, EtherCAT, Ethernet/IP, CC-Link, and more.

In addition, it also supports TSN implementation of these protocols, including AVB/TSN, Ethernet OPC-UA, Profinet Over TSN. This makes the i.MX 94 family well-suited for current and future industrial automation applications.

Advanced Security Protects Against Quantum Attacks

Meanwhile, the i.MX 94 family is NXP’s first applications processor to support post-quantum, public key cryptography. Therefore, allowing it to withstand attacks by quantum computers, and manage security of equipment over a long lifecycle.

The integrated EdgeLock Secure Enclave (Advanced Profile) allows it to set the equipment and restore it to a trusted state at any time and provides advanced security capabilities. This includes secure boot, secure debug, and secure update of the processor based on post-quantum cryptography without compromising performance.

It also features runtime protections, such as expelling an attacker with automatic recovery to a trusted state, or EdgeLock 2GO key management.

For industrial TSN and automotive connectivity applications, the i.MX 94 incorporates EdgeLock Accelerator (Prime), a crypto-accelerator enabling fast boot, and real-time, high-speed message signing, authentication and encryption at 5G speeds for secure communications.
