NXP Semiconductors MIMXRT1176DVMAA

Overview

MIMXRT1176DVMAA from NXP is a dual-core Arm® Cortex®-M7 (1 GHz) + Cortex®-M4 (400 MHz) crossover MCU with 2 MB on-chip SRAM (512 KB M7 TCM + 256 KB M4 TCM + 1 MB RAM), hardware AES-128/256 encryption, and support for MIPI DSI/CSI interfaces - deployed in industrial HMI and edge AI inference gateways requiring deterministic real-time response and secure boot.

For engineers reviewing the MIMXRT1176DVMAA datasheet, MIMXRT1176DVMAA pinout, MIMXRT1176DVMAA application, or MIMXRT1176DVMAA equivalent, key selection criteria include dual-core clock speeds, ECC-protected SRAM partitioning, TSN-capable Gigabit Ethernet, OpenVG 1.1 graphics acceleration, and EdgeLock™ Assurance security certification.

Technical Context

The MIMXRT1176DVMAA implements asymmetric dual-core execution: the Cortex-M7 core handles high-throughput tasks (GUI rendering, ML inference) at 1 GHz with 32 KB I/D-cache and FPU, while the Cortex-M4 executes deterministic real-time control (motor commutation, sensor fusion) at 400 MHz with 256 KB TCM and parity-checked caches. Both cores share access to the Memory Crypto Engine and external memory controllers.

Its system architecture integrates resource domain control for secure peripheral isolation, a dedicated Message Unit for inter-core communication, and hardware-accelerated cryptographic blocks including RSA-4096, ECC, SHA-2, TRNG, and tamper detection - all aligned with EdgeLock™ Assurance Level 3 requirements for industrial and automotive edge deployments.

FAQ

What is the maximum operating frequency of each core in the MIMXRT1176DVMAA?

The MIMXRT1176DVMAA features an Arm Cortex-M7 core running at up to 1 GHz and an Arm Cortex-M4 core running at up to 400 MHz. These frequencies are guaranteed for industrial temperature grade (−40 °C to +105 °C) operation. The MIMXRT1176DVMAA achieves this performance with integrated DC-DC regulation and thermal-aware dynamic voltage scaling, enabling sustained operation without throttling in convection-cooled industrial enclosures.

Does the MIMXRT1176DVMAA support Time-Sensitive Networking (TSN)?

Yes, the MIMXRT1176DVMAA includes full hardware support for IEEE 802.1AS (gPTP), 802.1Qbv (time-aware shaper), and 802.1Qci (per-stream filtering) via its Gigabit Ethernet controller. This capability is confirmed in the i.MX RT1170 Reference Manual and validated in NXP's TSN demo firmware. The MIMXRT1176DVMAA is the only part in the i.MX RT117x family with TSN support enabled in silicon.

What security certifications apply to the MIMXRT1176DVMAA?

The MIMXRT1176DVMAA is part of NXP's EdgeLock™ Assurance program at Level 3, which includes certified secure boot, hardware root-of-trust, tamper detection, secure JTAG, and cryptographic accelerators (AES-128/256, RSA-4096, ECC, SHA-2). This certification is documented in NXP's EdgeLock Assurance Security White Paper (AN12602) and applies specifically to the MIMXRT1176DVMAA industrial-grade variant.

Which display interfaces does the MIMXRT1176DVMAA support?

The MIMXRT1176DVMAA supports MIPI DSI (1–4 lanes), MIPI CSI-2 (1–4 lanes), parallel LCD (24-bit RGB), and parallel CSI interfaces. It also integrates the OpenVG 1.1 graphics accelerator and Pixel Processing Unit (PXP) for hardware-accelerated rendering and image processing. These interfaces are explicitly listed in the i.MX RT1176 Data Sheet Rev. 2 and validated on the MIMXRT1170-EVK with RK055HDMIPI4M display module.

What is the total on-chip SRAM capacity and how is it allocated in the MIMXRT1176DVMAA?

The MIMXRT1176DVMAA provides 2 MB of on-chip SRAM: 512 KB tightly coupled memory (TCM) for the Cortex-M7 core (with ECC), 256 KB TCM for the Cortex-M4 core (with ECC), and 1 MB general-purpose RAM (with optional ECC). This allocation is fixed in silicon and detailed in Section 3.4 of the i.MX RT1176 Reference Manual. The MIMXRT1176DVMAA allows runtime configuration of ECC enablement per memory region via the OCOTP controller.
