MIMX9111CVXXJAA

Overview

The MIMX9111CVXXJAA is an industrial-grade application processor from the NXP i.MX 91 family, featuring a single Arm Cortex-A55 core operating at 1.4 GHz with 256 KB L2 cache. It supports up to 2.4 GT/s LPDDR4 memory with inline ECC and includes 384 KB internal SRAM. Connectivity comprises two USB 2.0 ports, one Gigabit Ethernet port with TSN support, two CAN FD interfaces, eight UARTs, eight SPIs, and eight I2Cs. The device utilizes a 9x9 mm FCCSP package and operates within a junction temperature range of -40°C to 105°C.

Feature Summary

• Integrates EdgeLock secure enclave for autonomous management of root of trust, secure boot, and cryptographic services.
• Supports Industry 4.0 requirements via Time-Sensitive Networking (TSN) hardware capability on the Ethernet interface.
• Includes error correcting codes (ECC) in internal caches, SRAM, and the external LPDDR4 memory interface.
• Features machine learning acceleration through dual 64-bit Arm NEON floating-point units and specific instruction set support.

Applications

• Industrial Human-Machine Interfaces (HMI)
• EV Charging Stations
• Smart Home Matter Controllers/Devices
• Building Safety and Security Systems

Procurement Notes

Verify that the ordering suffix 'JAA' corresponds to the Industrial qualification (-40°C to 105°C Tj) and the 9x9 mm FCCSP package as listed in the official part differentiation table. Confirm compatibility with the PF9453 PMIC for power design. Ensure software support aligns with the Yocto-based BSP and required real-time operating system dependencies.

Selection Notes

Select this model for applications requiring deterministic control loops enabled by TSN on a single Ethernet port. It serves as a pin-compatible entry point into the i.MX 9 series, allowing scalability to higher-performance models like the i.MX 93 without redesigning the hardware platform. Ideal for cost-sensitive industrial IoT devices needing robust security features.

Part Context

This component belongs to the i.MX 91 family, positioned as the entry-level solution within the broader i.MX 9 EdgeVerse portfolio. It shares hardware and software commonality with the i.MX 93 family, facilitating product line scaling and maximizing development investment reuse. The family targets next-generation Linux-based IoT and industrial applications requiring high energy efficiency.

Replacement Considerations

MIMX9111DVXXJAA: Commercial grade variant with identical specifications but limited to 0°C to 95°C junction temperature.
