NXP i.MX 8XLite SoC is a cost-optimized version of NXP i.MX 8X automotive processor with up to two Cortex-A35 cores, one Cortex-M4F real-time core, and in a GPU-less configuration since it lacks the Vivante GPU found in i.MX 8X family.
The headless processor also comes with dedicated Hardware Security Modules (HSM) to enable telematics solutions, vehicle-to-everything (V2X) applications including vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) solutions, road infrastructure connectivity, as well as IIoT applications such as industrial equipment and building automation.

The new NXP i.MX 8XLite appears to benefit from additional security features including NXP EdgeLock security, and products based on the processor can be made to meet the FIPS 140-3 security standard defined by the US government, and used in applications ranging from V2X to critical infrastructure applications.
Software support includes a Linux BSP, firmware the V2X accelerator, and AUTOSAR MCAL. There will also be an i.MX 8XLite evaluation kit that will come with board design files and a hardware design guide. Public information is limited at this time, with NXP i.MX 8XLite processor still in “preproduction”.
