Product details
Overview
MIMX9131DVVXJAA from NXP is a secure, energy-efficient Arm Cortex-A55-based applications processor for Linux-powered edge devices, operating at 1.4 GHz with 256 KB L2 cache, LPDDR4 support up to 2.4 GT/s, and integrated EdgeLock® secure enclave. It targets industrial HMI, EV charging stations, and smart home Matter controllers requiring deterministic Ethernet, CAN FD, and real-time audio/video interfaces.
For engineers reviewing the MIMX9131DVVXJAA datasheet, MIMX9131DVVXJAA pinout, MIMX9131DVVXJAA application, or MIMX9131DVVXJAA equivalent, key selection considerations include commercial-temperature FCCSP package (11 × 11 mm, 0.5 mm pitch), dual Gigabit Ethernet with TSN on one port, dual CAN FD, and hardware-enforced security via EdgeLock®.
Technical Context
The MIMX9131DVVXJAA implements a single-core Arm Cortex-A55 CPU with Armv8.2 instruction set support, dual 64-bit NEON FPUs, and two-level branch prediction - optimized for Linux and RTOS execution. It integrates an EdgeLock® secure enclave with autonomous root-of-trust, secure boot, runtime attestation, and cryptographic services including AES, SHA, and TRNG.
Memory subsystem includes 384 KB on-die OCRAM, inline ECC for LPDDR4 interface, and error correction for L1/L2 caches and SRAM. Connectivity features two Gigabit Ethernet MACs (one with IEEE 1588 PTP and TSN), two USB 2.0 ports, eight UARTs, eight SPIs, eight I²Cs, two I³Cs, and two CAN FD controllers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar applications processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MIMX9131CVVXJAA | Same core, package, and peripheral set but rated for industrial temperature range (–40°C to +105°C). | Required for HVAC, energy metering, or outdoor EV charging where ambient thermal stress exceeds commercial spec. | Select MIMX9131CVVXJAA when extended temperature operation is mandatory; otherwise MIMX9131DVVXJAA suffices for indoor consumer/industrial edge use cases. |
| MIMX9111DVXXJAA | 9 × 9 mm FCCSP package, single Gigabit Ethernet, 1.4 GHz A55, no TSN hardware. | Suitable for cost-sensitive, space-constrained applications like smart lighting or compact HMI where deterministic networking is not required. | Choose MIMX9111DVXXJAA only if board area reduction and reduced Ethernet capability are acceptable trade-offs for lower BOM cost. |
Compared with MIMX9131CVVXJAA, the MIMX9131DVVXJAA offers identical functionality at lower thermal qualification cost; compared with MIMX9111DVXXJAA, it adds TSN-capable dual Ethernet and larger package footprint - critical for scalable gateway and control applications demanding future-proof I/O headroom.

FAQ
What is the maximum operating frequency of the MIMX9131DVVXJAA?
The MIMX9131DVVXJAA features a single Arm Cortex-A55 core operating at up to 1.4 GHz. This frequency is guaranteed under commercial temperature conditions (–40°C to +105°C junction) with appropriate power delivery and thermal management. The MIMX9131DVVXJAA does not support dynamic frequency scaling beyond this rated speed.
Does the MIMX9131DVVXJAA support Time-Sensitive Networking (TSN)?
Yes, the MIMX9131DVVXJAA includes dedicated TSN hardware acceleration on its first Gigabit Ethernet port (ENET1), supporting IEEE 802.1AS (time synchronization), 802.1Qbv (time-aware shaper), and 802.1Qbu (frame preemption). This enables sub-10 µs jitter for deterministic control in industrial automation applications using the MIMX9131DVVXJAA.
Which power management IC is recommended for use with the MIMX9131DVVXJAA?
NXP specifies the PF9453 as the companion PMIC for the MIMX9131DVVXJAA. It provides all required voltage rails - including VDD_ARM, VDD_SOC, VDD_DDR, and VDD_IO - with precise sequencing, monitoring, and fault response. The MIMX9131DVVXJAA BSP includes pre-configured drivers and initialization tables for the PF9453, ensuring robust power-up and thermal management.
Is the MIMX9131DVVXJAA pin-compatible with other i.MX 9 series processors?
Yes, the MIMX9131DVVXJAA uses the same 11 × 11 mm, 0.5 mm pitch FCCSP package and pinout as the i.MX 93 family, enabling hardware reuse across performance tiers. However, it is not pin-compatible with the smaller 9 × 9 mm MIMX9111DVXXJAA variant due to differing ball count and signal mapping - board redesign is required for migration between those packages.
What security certifications does the MIMX9131DVVXJAA support out of the box?
The MIMX9131DVVXJAA integrates the EdgeLock® secure enclave, which supports NIST SP 800-193 platform firmware resilience, PSA Certified Level 3, and Common Criteria EAL4+ ready configurations. While final certification depends on system-level implementation, the MIMX9131DVVXJAA provides hardware roots of trust, secure boot, and attestation primitives required for achieving these standards in end products.
