NXP Semiconductors MIMX9351XVTXMAB

Overview

MIMX9351XVTXMAB from NXP Semiconductors is a single-core Arm® Cortex®-A55 (1.7 GHz) + Arm® Cortex®-M33 (250 MHz) applications processor with integrated Neural Processing Unit (NPU), dual Gigabit Ethernet (one with TSN), MIPI CSI-2 and DSI, LPDDR4X support, and EdgeLock® secure enclave - designed for extended industrial HMI, EV charging control, and touchless access systems operating from –40°C to +125°C.

For engineers reviewing the MIMX9351XVTXMAB datasheet, MIMX9351XVTXMAB pinout, MIMX9351XVTXMAB application, or MIMX9351XVTXMAB equivalent, key selection criteria include its 14 × 14 mm FCBGA306 package, NPU-disabled configuration, extended temperature qualification, dual-GbE with TSN capability, and secure boot with TrustZone-A/M.

Technical Context

The MIMX9351XVTXMAB implements a heterogeneous compute architecture: one Cortex-A55 core handles Linux-based application workloads at up to 1.7 GHz with 64 KB L2 cache and Neon/FPU, while the Cortex-M33 (250 MHz) manages real-time tasks, power state coordination, and peripheral offload. Its memory subsystem includes 640 KB on-chip RAM with ECC, LPDDR4X interface (3.7 GT/s, up to 2 GB), and FlexSPI for XIP-capable flash.

Connectivity is anchored by two Gigabit Ethernet controllers (one IEEE 1588/TSN-compliant), two FlexCAN-FD modules, dual I3C, eight LPUARTs, and three uSDHC interfaces supporting eMMC 5.1, SDXC, and SDIO - all routed through a centralized IOMUXC with GPIO interrupt capability and tamper detection support.

FAQ

What is the maximum operating temperature specification for the MIMX9351XVTXMAB?

The MIMX9351XVTXMAB is qualified for extended industrial operation with a junction temperature range of –40°C to +125°C. This rating is validated per JEDEC JESD22-A104 and confirmed in the IMX93XEC datasheet Rev. 8. Thermal design must maintain junction temperature within this limit under worst-case ambient and power conditions, leveraging its 14 × 14 mm FCBGA306 package with R_θJA = 21.7°C/W.

Does the MIMX9351XVTXMAB include an integrated Neural Processing Unit (NPU)?

No, the MIMX9351XVTXMAB has the NPU disabled. Per Table 2 of the IMX93XEC datasheet, this part number belongs to the "NPU Disabled" variant group. It retains full Cortex-A55 and Cortex-M33 functionality, LPDDR4X interface, TSN Ethernet, and EdgeLock® security - making it ideal for applications requiring deterministic real-time response without ML inference overhead.

Which display interfaces does the MIMX9351XVTXMAB support natively?

The MIMX9351XVTXMAB supports MIPI DSI (4-lane, up to 1080p60), LVDS (4-lane, up to 1366x768p60), and parallel RGB (up to 1366x768p60) via its integrated LCDIF controller. All three outputs are mutually exclusive per design; no external bridge IC is required. The MIPI DSI interface complies with v1.2 and supports 80–1500 Mbps per lane in high-speed mode.

What Ethernet capabilities does the MIMX9351XVTXMAB provide?

The MIMX9351XVTXMAB integrates two independent Gigabit Ethernet controllers. One supports Energy Efficient Ethernet (EEE), AVB, and IEEE 1588; the other adds Time-Sensitive Networking (TSN) features including 802.1AS (time sync), 802.1Qbv (time-aware shaper), and 802.1Qci (per-stream filtering). Both operate simultaneously and are fully hardware-accelerated.

Is the MIMX9351XVTXMAB pin-compatible with other i.MX 93 variants in the same package size?

Yes, all i.MX 93 parts in the 14 × 14 mm FCBGA306 package - including MIMX9351XVTXMAB, MIMX9352XVTXMAB, and MIMX9332XVTXMAC - share identical pinouts and ball assignments per the IMX93XEC Package Information section. This enables hardware reuse across performance tiers (single/dual A55) and feature sets (NPU on/off) without PCB redesign.
