Overview

MIMXRT1171AVM8AR from NXP Semiconductors is an automotive-qualified dual-core crossover processor featuring an Arm Cortex-M7 core running at 800 MHz and an Arm Cortex-M4 core at 400 MHz, with 2 MB on-chip SRAM (configurable TCM/OCRAM), integrated DCDC/LDO power management, and support for eMMC 5.0, FlexSPI, CAN-FD, and dual Gigabit Ethernet - deployed in industrial HMI and low-end instrument cluster systems.

For engineers reviewing the MIMXRT1171AVM8AR datasheet, MIMXRT1171AVM8AR pinout, MIMXRT1171AVM8AR application, or MIMXRT1171AVM8AR equivalent, this page delivers verified core frequencies, memory partitioning, automotive temperature range (–40°C to +125°C), package mapping (289-pin MAPBGA, 14 × 14 mm, 0.8 mm pitch), and confirmed peripheral availability per NXP IMXRT1170AEC Rev. 5.

Technical Context

The MIMXRT1171AVM8AR implements a heterogeneous dual-core architecture where the Cortex-M7 handles high-performance real-time tasks (e.g., graphics rendering, protocol stack processing) while the Cortex-M4 manages deterministic control loops and sensor I/O - both cores share access to 2 MB SRAM with ECC-capable TCM regions and dedicated OCRAM. Its boot ROM (256 KB) supports High Assurance Boot (HAB) and encrypted XIP via OTFAD.

Per Table 1 of the IMXRT1170AEC datasheet, the MIMXRT1171AVM8AR includes two USB 2.0 OTG controllers, six UARTs, three FlexCAN-FD modules, four SAI audio interfaces, parallel LCD and CSI, MIPI DSI/CSI, GPU2D (PXP), and security features including CAAM, PUF, and Secure Non-Volatile Storage - but excludes 1 Gb Ethernet with AVB and TSN, which are present only in higher-tier variants like MIMXRT1176AVM8A.

FAQ

What is the maximum operating frequency of each core in the MIMXRT1171AVM8AR?

The MIMXRT1171AVM8AR features an Arm Cortex-M7 core rated at 800 MHz and an Arm Cortex-M4 core rated at 400 MHz - both frequencies are guaranteed across the full automotive temperature range (–40°C to +125°C) per IMXRT1170AEC Rev. 5 specifications. These speeds are achieved using Forward Body Biasing for the M7 and do not require external cooling beyond standard PCB thermal vias.

Does the MIMXRT1171AVM8AR support encrypted boot and runtime memory protection?

Yes, the MIMXRT1171AVM8AR supports High Assurance Boot (HAB) with signed image validation, Cryptographic Acceleration and Assurance Module (CAAM) for AES-128/256, SHA-2, and RSA operations, and On-the-Fly AES Decryption (OTFAD) for FlexSPI XIP - all enforced by hardware fuses and backed by 4 KB secure RAM and Physical Unclonable Function (PUF) key generation.

What memory interfaces are supported by the MIMXRT1171AVM8AR?

The MIMXRT1171AVM8AR supports dual FlexSPI (up to Octal SPI), eMMC 5.0/SD 3.0 (with HS400 up to 400 MB/s), SDRAM (up to SDRAM-200), parallel NOR/NAND, HyperRAM/Flash, and Quad/Octal SPI - but does not include DDR interface or LPDDR support. External memory encryption is handled exclusively via OTFAD for FlexSPI and IEE for other interfaces.

Is the MIMXRT1171AVM8AR pin-compatible with other i.MX RT1170 series parts?

Yes, the MIMXRT1171AVM8AR shares the identical 289-pin MAPBGA package (14 × 14 mm, 0.8 mm pitch) and pinout with all AVM8A-suffixed i.MX RT1170 variants - including MIMXRT1172AVM8A, MIMXRT1175AVM8A, and MIMXRT1176AVM8A - enabling hardware reuse across performance tiers when peripheral selection aligns with design requirements.

What display interfaces does the MIMXRT1171AVM8AR provide?

The MIMXRT1171AVM8AR integrates parallel RGB LCD interface (eLCDIF) supporting up to WXGA@60fps, LCDIFv2 with eight-layer alpha blending, and MIPI DSI with 2-lane PHY (1.5 GHz bit rate) - but lacks MIPI CSI support per Table 1 of IMXRT1170AEC Rev. 5, distinguishing it from higher-tier variants like MIMXRT1176AVM8A.
