• Integrated Data Path Acceleration Architecture (DPAA) for efficient packet classification and distribution.
• Hardware-enforced memory access controls via CoreLink CCI-400 coherent interconnect and ARM I/O MMU.
• Supports fanless platform designs through low total system power consumption.

Microprocessors Applications

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

Microprocessors Procurement Notes

Verify the specific ordering suffix against official NXP documentation to confirm package type, temperature grade, and security features. Ensure compatibility with required DDR3L or DDR4 memory configurations. Confirm that the selected variant aligns with the intended application's thermal and performance requirements before finalizing procurement.

Microprocessors Selection Notes

Select this component for applications requiring a balance of processing power and power efficiency in small-form-factor designs. The dual-core configuration offers significant performance improvements over previous generations while maintaining economic BOM optimization. Consider the integrated security engine if hardware-accelerated encryption is required for network traffic.

Microprocessors Part Context

This processor belongs to the QorIQ Layerscape LS1023A family, which shares architectural similarities with the quad-core LS1043A. Both processors target enterprise edge, industrial, and networking applications, offering flexible I/O packages suitable for fanless designs. The LS1023A specifically provides a cost-effective solution for applications not requiring the full four-core capacity of its sibling.
