MIMX9331CVVXMAB

The MIMX9331CVVXMAB is an industrial-qualified microprocessor from the i.MX 9331 family that combines high-efficiency application processing and real-time control. It integrates dual Arm® Cortex®-A55 application cores alongside an Arm® Cortex®-M33 for low-power and real-time tasks, plus a Neural Processing Unit (NPU) for accelerated machine-learning inference.

Designed for embedded edge and industrial systems, the device targets smart home, building control, contactless HMI, IoT edge, and industrial automation applications where a mix of application throughput, real-time responsiveness, and on-chip security is required.

Key Features

• Core processing  Dual Arm® Cortex®-A55 application cores (64-bit) with an Arm® Cortex®-M33 real-time core for responsive control and power-efficient background tasks.
• Neural and media acceleration  On-chip Neural Processing Unit (NPU) to accelerate machine-learning inference and a Media Processing Engine (MPE) with Arm® NEON™ for multimedia workloads.
• Memory subsystem  LPDDR4/LPDDR4X external memory support with inline ECC and a rich on-chip memory complement including boot ROMs and tightly coupled memory.
• Display and camera interfaces  Integrated controllers for LCD, LVDS, MIPI-CSI (camera) and MIPI-DSI (display) to support HMI and vision subsystems.
• High-bandwidth networking  Dual 1 Gbps Ethernet controllers (one supporting Time Sensitive Networking) and CAN‑FD for robust industrial connectivity.
• USB and storage  Multiple USB 2.0 ports and uSDHC interfaces including eMMC 5.1 and SDXC/SDIO support for flexible host and mass-storage options.
• Security features  Boot security, cryptography engines, eFuse, true random number generator, secure RTC and tamper detection for device and data protection.
• Industrial qualification & mounting  Industrial-qualified part with surface-mount package, and RoHS compliance for regulated deployments.
• Real-time and low-power support  Cortex‑M33 operation up to 250 MHz for stand-by monitoring and low-power control while application cores are power-gated.

Typical Applications

• Industrial HMI  Drives touch and display interfaces with integrated display controllers and application cores for graphics pipeline and user interaction.
• Industrial vision and scanning  Image sensor interface and on-chip image processing support camera input, preprocessing and ML inference at the edge.
• IoT edge and building control  Combination of application processing, real-time control, and secure boot/cryptography fit gateways and building automation nodes.
• Energy and charging systems  Networking and real-time control capabilities support metering, EV charging infrastructure, and energy grid equipment.

Unique Advantages

• Balanced application and real-time cores: Dual Cortex‑A55 application cores paired with a Cortex‑M33 provide high-level OS-capable processing plus deterministic control.
• On-device ML acceleration: Integrated NPU reduces reliance on external accelerators for inference workloads, simplifying designs that require local AI processing.
• Robust industrial connectivity: Dual Gigabit Ethernet (one with TSN) and CAN‑FD enable low-latency, deterministic networked control and gateway functions.
• Comprehensive security fabric: Boot security, cryptography, eFuses, RNG, secure RTC and tamper detection protect device identity and firmware integrity.
• Flexible multimedia I/O: Support for MIPI‑CSI, MIPI‑DSI, LCD and LVDS simplifies integration of cameras and displays in HMI and vision applications.
• Industrial qualification: Built and specified for industrial use, reducing redesign risk for deployment in industrial environments.
