MIMX8DL1AVNFZABR

Overview

The MIMX8DL1AVNFZABR is an i.MX 8XLite automotive-grade microprocessor featuring a dual-core Arm Cortex-A35 architecture operating at 1.2 GHz and a single Cortex-M4F core running at 264 MHz. It utilizes a 15 x 15 mm FCPBGA package with mixed pitch. The device supports 16-bit LPDDR4 memory up to 1200 MHz and DDR3L up to 933 MHz, both with inline ECC. Connectivity includes PCIe 3.0 (1-lane), dual USB 2.0, dual Gigabit Ethernet (one with AVB, one with TSN), three CAN/CAN-FD interfaces, six UARTs, four SAI modules, and a 6-channel ADC.

Feature Summary

• Dual Cortex-A35 cores provide high-performance processing with AArch64 support and ARM virtualization extensions for multi-OS deployment.
• Integrated V2X subsystem enables secure cryptographic acceleration specifically designed for vehicular communication packet verification and signing.
• Comprehensive security features include CAAM, Secure Boot, tamper detection, and dedicated secure RAM for key management.
• Robust connectivity suite supports Time-Sensitive Networking (TSN) and Audio Video Bridging (AVB) alongside standard industrial protocols.

Applications

• Automotive telematics and infotainment systems
• V2X (Vehicle-to-Everything) communication units
• Industrial control networks requiring real-time determinism

Procurement Notes

Verify the specific SCFW version required for your BSP release before integration, as mismatched firmware may cause reliability issues. Confirm that the FCPBGA package dimensions and mixed pitch requirements align with your PCB layout constraints. Ensure your design supports the necessary power-up sequencing for the multiple voltage domains specified in the electrical characteristics section.

Selection Notes

Select this part when dual-core performance is required alongside dedicated real-time handling via the Cortex-M4F. It is suitable for applications needing hardware-accelerated V2X security without the complexity of higher-end i.MX 8 families. Consider the specific Ethernet interface needs, as it provides distinct AVB and TSN ports for different traffic prioritization requirements.

Part Context

This component belongs to the NXP i.MX 8XLite family, which targets automotive and industrial markets. It shares architectural similarities with other i.MX 8 processors but focuses on cost-effective multicore processing with specialized V2X capabilities. The family includes variants with single or dual A35 cores and varying security certifications.

Replacement Considerations

MIMX8SL1AVNFZABR offers a single Cortex-A35 core configuration within the same package and pinout. MIMX8DL2AVNFZABR provides identical core counts but includes FIPS 140-3 certification for both SECO and V2X subsystems.
