The NXP i.MX 93W is NXP’s first integrated wireless MPU System-in-Package (SiP), featuring a dual-core Cortex-A55 processor alongside an iW610 WiFi 6, Bluetooth LE, and 802.15.4 tri-radio on a single chip.
This 14.2 x 12 mm package includes all necessary external radio components for wireless connectivity, replacing up to 60 discrete components on the PCB. NXP claims this reduces the PCB area, simplifies design and regulatory approval, and speeds up time-to-market.

NXP mentions support for Linux OS and FreeRTOS, with Linux likely running on the Cortex-A55 cores and FreeRTOS on the Cortex-M33 core. As the i.MX 93W combines an NXP i.MX 93 with an iW610 and passive components, the software support should align with that of two-chip designs. Target applications include smart home hubs, medical sensors, and energy grid devices.
Wireless connectivity integration is rare in application processors, with similar examples like the Allwinner V821 and the Qualcomm Snapdragon 410E. NXP introduced the i
