MIMX9332CVVXMABR

Overview

The MIMX9332CVVXMABR is an NXP Semiconductors i.MX 93 series application processor featuring a dual-core ARM Cortex-A55 architecture with a maximum clock frequency of 1.7 GHz and a secondary ARM Cortex-M33 core operating at 250 MHz. It utilizes a 64-bit data bus width and integrates an Arm Ethos-U65 microNPU for machine learning acceleration. The device operates within a temperature range of -40°C to +105°C, supported by a 900 mV working supply voltage. It employs a 306-ball FCBGA package (FCBGA-306) suitable for surface mount technology.

Feature Summary

• Integrates dual-core ARM Cortex-A55 processors alongside an ARM Cortex-M33 real-time core for heterogeneous computing.
• Includes an Arm Ethos-U65 microNPU specifically designed for efficient edge machine learning inference acceleration.
• Features the EdgeLock Secure Enclave subsystem to provide advanced hardware-based information security.
• Supports high-speed external memory interfaces including LPDDR4/LPDDR4X with inline ECC capabilities.

Applications

• Industrial Human-Machine Interfaces (HMI)
• Automotive infotainment and instrument clusters
• IoT gateways and smart energy meters
• Machine vision systems

Procurement Notes

Verify the specific suffix 'BR' against the official datasheet to confirm it denotes the reel packaging format rather than a functional variant. Ensure compatibility with the required power management IC, such as the PCA9451A, for proper voltage regulation. Confirm that the design supports the 306-ball FCBGA footprint and thermal requirements for the industrial temperature range.

Selection Notes

Select this component when a balance of high-performance computing and low-power real-time processing is required. The inclusion of the microNPU makes it suitable for applications needing on-device AI inference without external accelerators. Consider the 306-ball package size relative to board space constraints compared to smaller variants in the i.MX 93 family.

Part Context

This processor belongs to the i.MX 93 family, which targets the EdgeVerse intelligent edge solution portfolio. It is positioned as a power-efficient MPU offering integrated security and multimedia capabilities. The series supports various operating systems including Linux, FreeRTOS, and QNX, catering to diverse embedded software ecosystems.

Replacement Considerations

Check for other i.MX 93 variants with different pin counts or core configurations if package availability is an issue. Verify if lower-tier models meet the specific performance requirements before substituting.
