MIMX9131DVVXJAA

Overview

The MIMX9131DVVXJAA is a commercial-grade i.MX 91 application processor featuring an Arm Cortex-A55 core running at 1.4 GHz with 256 KB L2 cache. It integrates two Gigabit Ethernet MACs (one supporting TSN), two USB 2.0 controllers, and two CAN FD interfaces. The device supports up to 2.4 GT/s LPDDR4 memory with inline ECC and includes 384 KB internal SRAM. Connectivity options include eight UARTs, eight SPIs, eight I2Cs, and two I3C buses. It utilizes the PF9453 PMIC and operates within a standard industrial temperature range of -40°C to 105°C junction.

Feature Summary

• Integrates EdgeLock secure enclave for autonomous security management including root of trust and secure boot
• Supports Industry 4.0 deterministic control via Time-Sensitive Networking hardware capabilities on one Ethernet port
• Features enhanced reliability through error correcting codes in internal caches and LPDDR4 interface
• Provides machine learning acceleration support via dual 64-bit Arm NEON floating-point units

Applications

• Industrial HVAC systems and building safety detectors
• EV charging stations and energy metering devices
• Smart home Matter controllers and connected appliances
• Medical ventilator pumps and vital signs monitors

Procurement Notes

Verify the specific ordering suffix matches the required qualification grade and package dimensions. Confirm that the target application environment aligns with the commercial temperature rating specified for this part number. Ensure system design accounts for the integrated PF9453 PMIC requirements. Cross-reference pin compatibility if migrating from other i.MX 9 series components.

Selection Notes

Select this model for applications requiring high-performance Linux processing with robust connectivity features. The inclusion of TSN-capable Ethernet makes it suitable for precise time-synchronization needs in industrial automation. Consider the pin-compatible i.MX 93 family if future scalability or additional multimedia interfaces are anticipated without redesigning the hardware platform.

Part Context

This component belongs to the NXP i.MX 91 applications processor family, designed as an entry point into the i.MX 9 series. It offers hardware and software commonality with the i.MX 93 family to facilitate product line scaling. The processor is part of the EdgeVerse portfolio and supports long-term supply continuity through NXP's Product Longevity program.

Replacement Considerations

MIMX9131CVVXJAA serves as the industrial-qualified equivalent within the same package and performance tier.
