MIMX9111DVXXJAA

Overview

The MIMX9111DVXXJAA is a commercial-grade i.MX 91 application processor featuring an Arm Cortex-A55 core operating at 1.4 GHz with 256 KB L2 cache. It integrates the EdgeLock secure enclave and supports Linux/RTOS. Connectivity includes one Gigabit Ethernet port with TSN, two USB 2.0 ports, two CAN FD interfaces, eight UARTs, eight SPIs, and eight I2Cs. Memory support comprises up to 2.4 GT/s LPDDR4 with inline ECC, Octal SPI, and three SD/eMMC ports. The device utilizes a 9x9 mm FCCSP package.

Feature Summary

• Integrates EdgeLock secure enclave for autonomous security management including root of trust and secure boot
• Supports Industry 4.0 deterministic control via Time-Sensitive Networking (TSN) on the Ethernet interface
• Provides hardware error correction codes (ECC) for internal SRAM, caches, and external LPDDR4 memory
• Includes dedicated audio interfaces such as SAI, PDM microphone input, and Medium Quality Sound output

Applications

• Industrial HVAC systems and heat metering
• EV charging stations and energy metering
• Smart home Matter controllers and connected appliances
• Building safety and security detectors
• Essential industrial HMI panels

Procurement Notes

Verify the specific ordering suffix against NXP documentation to confirm package dimensions and temperature qualification. Ensure the selected variant matches the required interface count, as the DVXX suffix indicates a single Ethernet port configuration. Confirm supply longevity terms under the Product Longevity program before finalizing procurement plans.

Selection Notes

Select this model when a single high-speed Ethernet connection with time-synchronization capabilities is sufficient. The 9x9 mm package offers a compact footprint suitable for space-constrained designs compared to the 11x11 mm variants. Consider the pin-compatible i.MX 93 family if future scaling requires additional Ethernet ports or higher performance without redesigning the hardware platform.

Part Context

This component belongs to the i.MX 91 family, serving as an entry point into the broader i.MX 9 series. It shares hardware and software commonality with the i.MX 93 family, allowing developers to reuse investments and scale product lines efficiently. The family targets next-generation Linux-based IoT and industrial applications requiring optimized security and energy efficiency.

Replacement Considerations

MIMX9131DVVXJAA: Offers identical processing performance but includes two Gigabit Ethernet ports instead of one. Uses a larger 11x11 mm FCCSP package while maintaining pin compatibility with the i.MX 91 family for potential hardware reuse.
