NXP i.MX 91 single-core Cortex-A55 SoC to power Linux-based cost-optimized edge devices
NXP has just unveiled the NXP i.MX 91 single-core Cortex-A55 processor following the introduction of the i.MX 93 in 2021, and designed for cost-optimized edge devices running Linux. The NXP i.MX 93 processor comes with up to two Cortex-A55 cores, a Cortex-M33 real-time core, and an Ethos U65 microNPU, but targeting entry-level Linux systems, the NXP i.MX 91 processor does without the real-time core and the AI acceleration, while still integrating NXP EdgeLock Secure Enclave, and the company highlights support for multiple wireless connectivity options through companion chips such as the IW612 that supports Wi-Fi 6, Bluetooth 5.2, 802.15.4, and the new Matter protocol.
