Microprocessors Procurement Notes

Verify export compliance requirements before procurement, as this product may require additional documentation for shipment from the United States. Confirm that the specific ordering suffix matches the required security configuration and temperature grade. Ensure compatibility with existing PCB layouts due to the specific 21x21 mm package footprint. Validate power supply designs against the 1 V operating voltage specification.

Microprocessors Selection Notes

Select this component for applications requiring a balance of networking throughput and industrial reliability. The dual-core configuration offers a cost-effective alternative to quad-core variants while maintaining Layerscape ecosystem compatibility. Consider the 1.4 GHz frequency for sufficient processing headroom in embedded networking tasks. Evaluate the BOM optimization benefits for low-layer PCB designs compared to previous generation processors.

Microprocessors Part Context

This processor belongs to the QorIQ LS1023A series, designed specifically for small-form-factor networking and industrial infrastructure. It serves as the two-core counterpart to the LS1043A quad-core processor. The device leverages the same flexible I/O package and pin-compatible design, allowing scalability within the Layerscape portfolio. It targets economic low-layer PCB implementations with optimized power consumption.

Microprocessors Replacement Considerations

The LS1023AXN7PQB is a compatible variant within the same series offering identical specifications.
