LS1023AXE8MQB

Microprocessors Overview

The NXP LS1023AXE8MQB is a dual-core, 64-bit ARM Cortex-A53 microprocessor from the QorIQ Layerscape LS1023A series. It operates at a maximum clock frequency of 1.6 GHz and utilizes an FCPBGA-780 package with a 23x23 mm footprint. The processor integrates 32 KB instruction and data L1 caches per core, alongside a shared 1 MB L2 cache. It supports DDR3L/DDR4 SDRAM memory interfaces and includes integrated security engines, Frame Manager, and QUICC Engine technology for networking offloads.

• QUICC Engine providing legacy protocol support for HDLC, TDM, and PROFIBUS

Microprocessors Applications

• Branch office routers
• vCPE and edge equipment
• Multi-protocol IoT gateways
• Industrial PLC and control systems
• Security appliances

Microprocessors Procurement Notes

Verify the specific suffix 'MQB' against official NXP documentation to confirm temperature range and feature set, as ordering suffixes define exact operational parameters. Confirm current availability status directly with the manufacturer or authorized distributors, as supply conditions for this component may vary. Ensure compatibility with existing board designs regarding the FCPBGA-780 package dimensions and pinout requirements before procurement.

Microprocessors Selection Notes

Select this component for applications requiring a balance of processing power and energy efficiency in small-form-factor designs. The dual-core configuration offers a cost-effective alternative to quad-core variants while maintaining support for high-speed networking interfaces. Consider the 1.6 GHz operating speed and 1 MB L2 cache when evaluating throughput requirements for network-intensive workloads.

Microprocessors Part Context

This part belongs to the QorIQ Layerscape LS1023A family, designed specifically for embedded networking and industrial infrastructure. It serves as the dual-core counterpart to the quad-core LS1043A, sharing architectural similarities such as the CoreLink CCI-400 coherent interconnect and SMMU support. The series targets economic low-layer PCB designs with optimized BOM costs.

Microprocessors Replacement Considerations

The LS1023ASN8QQB is a documented variant within the same LS1023A family offering similar core specifications.
