MIMX8ML8CVNKZAB

Overview

The MIMX8ML8CVNKZAB is an industrial-grade i.MX 8M Plus quad-core microprocessor featuring four Arm Cortex-A53 cores operating at 1.6 GHz and a dedicated Cortex-M7 core running up to 800 MHz for real-time control. It integrates a Neural Processing Unit (NPU) delivering 2.3 TOPS, dual Image Signal Processors (ISP), and advanced multimedia capabilities including H.265/H.264 video encode/decode. The device supports LPDDR4-4000 and DDR4-3200 memory with inline ECC, ensuring high reliability in harsh environments. Operating within a temperature range of -40°C to 105°C, it utilizes a 15x15 mm FCBGA package.

Feature Summary

• Integrated NPU providing hardware acceleration for machine learning inference tasks such as image recognition and speech processing.
• Dual camera interfaces supporting HDR ISP with aggregate performance up to 375 MPixels/s for advanced vision systems.
• Industrial reliability features including DRAM Inline ECC and secure boot mechanisms via High Assurance Boot (HAB).
• Real-time control capability enabled by the integrated Cortex-M7 core alongside the main application processors.

Applications

• Industrial automation and Industry 4.0 gateway applications requiring low latency and robust connectivity.
• Smart home and building automation systems utilizing advanced multimedia and voice processing.
• Machine learning and visual inspection systems leveraging the integrated NPU and dual ISPs.
• High-reliability IoT edge devices demanding secure data processing and extended temperature operation.

Procurement Notes

Verify the specific part number suffix against the manufacturer's current ordering guide to confirm silicon revision and qualification tier. Ensure compatibility with the required industrial temperature range (-40°C to 105°C) and package specifications (FCBGA 15x15 mm). Cross-reference the module list to confirm the presence of all necessary subsystems, such as the NPU and CAN-FD interfaces, as these vary across the i.MX 8M Plus family.

Selection Notes

Select this component when both high-performance multimedia processing and deterministic real-time control are required on a single chip. The inclusion of the Cortex-M7 allows for separation of safety-critical tasks from general-purpose computing. Consider the NPU capacity if deploying deep learning models locally. Verify that the external memory interface supports the desired LPDDR4 or DDR4 configuration with ECC requirements met by the internal controller.

Part Context

This processor belongs to the i.MX 8M Plus family, designed specifically for edge AI and industrial applications. It sits between the consumer-focused i.MX 8M Mini and the higher-performance i.MX 8 QuadMax. The '8' in the model indicates the Quad A53 configuration with full multimedia and NPU capabilities, while 'C' denotes the industrial temperature grade. It shares the same physical footprint as other variants in the series but offers distinct functional blocks.

Replacement Considerations

Direct substitutes within the same package include MIMX8ML6CVNKZAB (Quad without NPU) and MIMX8ML3CVNKZAB (Dual with NPU). For non-NPU industrial applications, MIMX8ML4CVNKZAB serves as a compatible alternative. Upgrades to higher clock speeds require moving to the i.MX 8M Plus 1.8 GHz variants, which may have different thermal characteristics.
