GPU-less NXP i.MX 8XLite Cortex-A35/M4 SoC is aimed at IIoT & V2X applications

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.

NXP i.MX 8XLite key features and specifications:

  • Processor complex
    • 1x or 2x Arm Cortex-A35 cores @ up to 1.2 GHz with 256KB L2 cache with ECC
    • 1x Arm Cortex-M4F core for real-time processing
  • Memory I/F – 16-bit DDR3L-1866 and LPDDR4-2400 with ECC protection
  • Storage I/F
    • 1x FlexSPI for fast boot from SPI NOR flash
    • 2x SD 3.0 card interfaces

    • RSA-1024, 2048, 3072, 4096 and secure key storage
    • Tamper-pins
    • Inline Encryption Engine (AES-128)
    • V2X Optimized High Security Module (HSM)
  • Power management – Recommended PMIC: PF7100 power management integrated circuit
  • Temperature Range
    • Automotive: -40° to 125° C Tj (AEC-Q100 Grade 2)
    • Industrial: -40° to 105° C Tj

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”.
