Product details
Overview
MIMX9311CVXXMAB from NXP Semiconductors is an industrial-grade Arm® Cortex®-A55 single-core applications processor operating at 1.7 GHz, integrated with a Cortex®-M33 real-time core (250 MHz), dual Gigabit Ethernet (one with TSN), parallel camera and display interfaces, and 3.2 GT/s LPDDR4X support in a 9 × 9 mm FCBGA208 package. It targets touchless HMI, EV charging control, and industrial automation gateways requiring deterministic low-power operation.
For engineers reviewing the MIMX9311CVXXMAB datasheet, MIMX9311CVXXMAB pinout, MIMX9311CVXXMAB application, or MIMX9311CVXXMAB equivalent, key selection criteria include its single A55 core configuration, industrial temperature range (−40°C to +105°C), absence of NPU, parallel-only imaging/display I/O, and 9 mm × 9 mm FCBGA208 footprint-critical for space-constrained embedded edge designs.
Technical Context
The MIMX9311CVXXMAB implements a heterogeneous dual-domain architecture: the Cortex-A55 domain handles Linux-based application processing and multimedia tasks, while the Cortex-M33 domain manages real-time control, power state coordination, and peripheral offload. Its memory subsystem includes 640 KB on-chip RAM with ECC, 256 KB cluster L3 cache, and a 16-bit LPDDR4X interface supporting inline ECC up to 2 GB.
Connectivity is centered on deterministic industrial I/O: one Gigabit Ethernet controller with IEEE 1588/AVB/EEE, one USB 2.0 host/device PHY, eight LPUARTs (up to 5 Mbps), two FlexCAN modules (CAN-FD capable), and dual I3C buses. Imaging and display are served exclusively via parallel interfaces-no MIPI CSI/DSI-enabling cost-optimized camera and LCD integration without high-speed SerDes complexity.

Pinout & Package
Package: 9 × 9 mm, 0.5 mm pitch Fine-Pitch Ball Grid Array (FCBGA208) with 208 solder balls. Thermal pad on underside for enhanced heat dissipation in sealed enclosures.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD_SOC | Core supply rail | 1.0 V ± 3% nominal; powers Cortex-A55/M33 cores and L1/L2 caches - requires tight regulation and local decoupling |
| NVCC_GPIO | GPIO I/O supply | 1.8 V / 3.3 V configurable bank supply - sets logic levels for all general-purpose digital I/Os |

FAQ
What is the maximum operating frequency of the Cortex-A55 core in the MIMX9311CVXXMAB?
The Cortex-A55 core in the MIMX9311CVXXMAB operates at a maximum frequency of 1.7 GHz. This speed is guaranteed across the full industrial temperature range (−40°C to +105°C) and under specified voltage and cooling conditions per the IMX93IEC datasheet Rev. 8. The MIMX9311CVXXMAB does not support dynamic frequency scaling beyond this rated maximum, and sustained operation at 1.7 GHz requires adherence to thermal design guidelines including proper PCB copper pour and heatsinking.
Does the MIMX9311CVXXMAB include a Neural Processing Unit (NPU)?
No, the MIMX9311CVXXMAB does not include a Neural Processing Unit. Per Table 2 of the IMX93IEC datasheet, the "NPU" column for MIMX9311CVXXMAB is marked "-", indicating absence. NPU functionality is present only in variants such as MIMX9321CVXXMAB and above. For AI inference on MIMX9311CVXXMAB, developers must rely on CPU-based NEON acceleration or offload to external accelerators.
What display and camera interfaces are supported by the MIMX9311CVXXMAB?
The MIMX9311CVXXMAB supports only parallel interfaces: an 8-bit parallel YUV/RGB camera input and a parallel RGB display output. It lacks MIPI CSI-2 and MIPI DSI physical layers entirely. Supported resolutions include up to 1366×768p60 for display and up to 200 MPixel/s pixel rate for camera input. These interfaces are optimized for cost-sensitive industrial displays and fixed-focus CMOS sensors without high-speed SerDes complexity.
What is the package type and ball count of the MIMX9311CVXXMAB?
The MIMX9311CVXXMAB uses a 9 × 9 mm Fine-Pitch Ball Grid Array (FCBGA) package with 208 solder balls and 0.5 mm pitch. This is explicitly confirmed in Table 2 of the IMX93IEC datasheet under the "Package" column and in Figure 1's nomenclature breakdown ("VX" = 9 × 9 mm, FCBGA208). The package includes an exposed thermal pad on the underside for thermal management in industrial enclosures.
Which Ethernet features are implemented in the MIMX9311CVXXMAB?
The MIMX9311CVXXMAB integrates two Gigabit Ethernet controllers: one supports Energy Efficient Ethernet (EEE), Audio Video Bridging (AVB), and IEEE 1588 Precision Time Protocol; the second adds Time-Sensitive Networking (TSN) capabilities on top of those features. Both controllers operate simultaneously and are fully independent, enabling segregated traffic domains-for example, one for HMI web services and one for deterministic control messaging-without software arbitration overhead.
