MIMX9322DVXXMAB

Soc System On Chip Overview

The MIMX9322DVXXMAB is a commercial-grade application processor from the NXP i.MX 93 family, designed for power-optimized edge applications. It features two Arm Cortex-A55 cores operating at up to 1.7 GHz and an Arm Cortex-M33 real-time core running at 250 MHz. The device integrates an Arm Ethos-U65 microNPU for machine learning acceleration and includes an EdgeLock secure enclave for robust security. Connectivity options include one Gigabit Ethernet controller with TSN support, one USB 2.0 port, and multiple serial interfaces. External memory supports up to 3.2 GT/s LPDDR4/LPDDR4X via a 16-bit interface. The processor is housed in a 9 x 9 mm FCBGA package with a 0.5 mm pitch.

Soc System On Chip Feature Summary

• One Gigabit Ethernet controller supporting TSN, IEEE 1588, and EEE
• Supports parallel display output and parallel camera input interfaces

Soc System On Chip Applications

• Smart home hubs and bridge devices
• Audio soundbars and smart speakers
• Smart doorbells and video entry systems
• Smart locks and thermostats
• Contactless human-machine interfaces (HMI)

Soc System On Chip Procurement Notes

Verify that the specific part number corresponds to the Commercial temperature grade data sheet (IMX93CEC). Confirm the silicon revision suffix matches the required hardware version. Ensure the design utilizes the correct PMIC solution to meet the strict power-up sequencing requirements defined in the reference manual.

Soc System On Chip Selection Notes

Select this model when a single Gigabit Ethernet port and one USB 2.0 interface are sufficient for the system architecture. This variant lacks MIPI DSI and LVDS display controllers, limiting output to parallel RGB displays. Verify that the external memory speed requirement does not exceed 3.2 GT/s, as higher speeds are reserved for larger package derivatives.

Soc System On Chip Part Context

This component belongs to the i.MX 93 series of power-efficient processors. It shares the same core architecture and peripheral set as other members but is differentiated by its reduced connectivity profile and smaller 9x9mm package footprint. It serves as a cost-effective option for embedded systems requiring moderate processing power without high-bandwidth display or camera interfaces.

Soc System On Chip Replacement Considerations

For pin-compatible upgrades within the same package, consider the MIMX9321DVXXMAB (single A55 core) or MIMX9312DVXXMAB (single A55 core, no NPU). For feature expansion requiring MIPI interfaces, the 11x11mm package variants such as MIMX9352DVVXMAB must be used, requiring PCB redesign.
