LS1043AXE7KQB

Microprocessors Overview

The NXP LS1043AXE7KQB is a quad-core, 64-bit ARM Cortex-A53 communications processor designed for embedded networking and industrial infrastructure. Operating at frequencies up to 1.6 GHz, it features a 1 MB L2 cache and integrates the QorIQ Data Path Acceleration Architecture (DPAA) for efficient packet processing. The device includes a four-lane 10 GHz SerDes supporting up to six Gigabit Ethernet ports with IEEE 1588, three PCIe Gen 2.0 interfaces, one SATA 3.0 port, and triple USB 3.0 controllers. It incorporates an integrated Security Engine (SEC 5.4), QUICC Engine technology for legacy protocols, and supports DDR3L/4 memory.

Microprocessors Procurement Notes

Verify the specific ordering suffix against official NXP documentation to confirm package type, temperature range, and security features. Ensure compatibility with required power supply designs and PCB layouts for fanless operation. Confirm availability through authorized distributors as product lifecycles may change.

Microprocessors Selection Notes

Select this processor for applications requiring high performance per watt in small-form-factor designs. It is suitable for environments needing hardware-based virtualization and robust security features. Consider the BOM optimization benefits for low-layer PCBs and single-clock designs when evaluating system costs.

Microprocessors Part Context

The LS1043A is part of the QorIQ Layerscape family, serving as a successor to dual-core 32-bit products like the LS1020A. It offers up to four times the performance of previous generations while maintaining energy efficiency. The processor is designed for enterprise edge, industrial, and networking applications, leveraging ARM's ecosystem for development.

Microprocessors Replacement Considerations

The LS1023A is the dual-core variant within the same family. For form, fit, and function compatibility, consider migration to other QorIQ LS series devices as recommended by NXP's Product Longevity program.
