NXP Semiconductors MIMX9351AVTYMAB

Overview

MIMX9351AVTYMAB from NXP Semiconductors is an automotive-qualified i.MX 93 applications processor featuring a single Arm® Cortex®-A55 core operating at up to 1.7 GHz, integrated Arm® Cortex®-M33 real-time controller (250 MHz), and neural processing unit (NPU) disabled. It supports LPDDR4X/LPDDR4 memory (up to 2 GB), dual Gigabit Ethernet with TSN support, MIPI CSI-2 (2-lane, 1080p30), and MIPI DSI (4-lane, 1080p60), targeting cost-optimized automotive gateways and driver monitoring systems.

For engineers reviewing the MIMX9351AVTYMAB datasheet, MIMX9351AVTYMAB pinout, MIMX9351AVTYMAB application, or MIMX9351AVTYMAB equivalent, key selection criteria include its AEC-Q100 Grade 2 qualification (-40°C to +125°C), absence of NPU acceleration, 14 × 14 mm FCBGA306 package with 0.65 mm pitch, and dual Ethernet with IEEE 1588/TSN timing precision for deterministic automotive networking.

Technical Context

The MIMX9351AVTYMAB implements a heterogeneous compute architecture: the Cortex-A55 handles Linux-based application processing while the Cortex-M33 manages real-time tasks including power state coordination and safety-critical monitoring. Its memory subsystem includes 256 KB cluster L3 cache with ECC, 640 KB on-chip RAM, and boot ROMs for both cores.

Connectivity is built around two FlexCAN modules supporting CAN-FD, dual GbE controllers (one with TSN), three uSDHC interfaces (eMMC 5.1, SDXC, SDIO), and eight LPUARTs. Security relies on Arm TrustZone-A/M, EdgeLock® secure enclave, TRDC with 16 domains, and BBSM with tamper detection and secure RTC.

FAQ

What is the maximum operating temperature range for MIMX9351AVTYMAB?

MIMX9351AVTYMAB is qualified to AEC-Q100 Grade 2 with a junction temperature range of –40°C to +125°C. This specification ensures reliable operation in under-hood and cabin-mounted automotive environments where thermal stress is significant. The device's thermal resistance (RθJA = 21.7°C/W) and flexible power domain partitioning support thermal management in compact enclosures without active cooling.

Does MIMX9351AVTYMAB include a neural processing unit (NPU)?

No, MIMX9351AVTYMAB has the NPU disabled. This configuration is explicitly defined in NXP's ordering information table and confirmed in the i.MX 93 Automotive Data Sheet (IMX93AEC Rev. 8). The absence of NPU reduces silicon area, power consumption, and software stack complexity - making MIMX9351AVTYMAB ideal for cost-sensitive automotive gateways where ML inference is handled externally or omitted entirely.

Which Ethernet features are supported by MIMX9351AVTYMAB?

MIMX9351AVTYMAB integrates two independent Gigabit Ethernet controllers: one supports Energy Efficient Ethernet (EEE), AVB, and IEEE 1588; the second adds Time-Sensitive Networking (TSN) capabilities including IEEE 802.1AS timestamping and 802.1Qbv time-aware shaping. Both controllers operate simultaneously and are fully accessible via Linux drivers in the NXP Yocto BSP, enabling deterministic inter-domain communication in automotive gateways.

What camera interfaces does MIMX9351AVTYMAB support?

MIMX9351AVTYMAB supports one 2-lane MIPI CSI-2 interface compliant with MIPI D-PHY v1.2 and CSI-2 v1.3, capable of up to 1.5 Gbps per lane (1080p30). It also supports parallel RGB/YUV camera input. The Image Sensor Interface (ISI) provides hardware-accelerated image downscaling, color space conversion, and interlaced-to-progressive processing - all essential for driver monitoring system (DMS) preprocessing pipelines.

Is MIMX9351AVTYMAB pin-compatible with other i.MX 93 variants?

Yes, MIMX9351AVTYMAB shares the same 306-ball FCBGA package (14 × 14 mm, 0.65 mm pitch) and identical pinout with MIMX9352AVTXMAC, MIMX9352AVTXMBC, and MIMX9331AVTXMAC. This enables hardware reuse across product tiers - for example, upgrading from MIMX9351AVTYMAB to MIMX9352AVTXMBC requires only firmware and BOM changes, with no PCB redesign needed.
