LS1023ABE9PQB

Microprocessors Overview

The LS1023ABE9PQB is a dual-core, 64-bit Arm Cortex-A53 microprocessor from the NXP QorIQ Layerscape family. It operates at a maximum clock frequency of 1.4 GHz and features 32 KB L1 instruction and data caches with ECC protection, alongside a 1 MB unified L2 cache. The device includes a Data Path Acceleration Architecture (DPAA) for packet processing, four SerDes lanes supporting up to 10 Gbps interfaces, and an integrated security engine. It utilizes a 780-ball FC-PBGA package measuring 23x23 mm and supports DDR3L/DDR4 memory.

Microprocessors Feature Summary

• Dual-core 64-bit Arm Cortex-A53 architecture with hardware-managed data coherency
• Integrated Data Path Acceleration Architecture (DPAA) for packet parsing and queue management
• Four high-speed SerDes lanes supporting PCIe, SATA, and Ethernet interfaces
• Built-in Trust Architecture and Security Engine (SEC) for secure boot and cryptographic acceleration

Microprocessors Applications

• Industrial gateways
• Wireless LAN access points
• Branch routers
• Embedded network infrastructure

Microprocessors Procurement Notes

Verify the specific ordering suffix against the official NXP LS1043A/LS1023A datasheet to confirm temperature range, speed grade, and package type. Ensure compatibility with required Linux enablement software (LDP) and reference designs. Confirm availability through authorized distributors as supply status may vary by region.

Microprocessors Selection Notes

Select this component for applications requiring reliable, power-efficient networking performance in industrial or embedded environments. The dual-core configuration offers a balance between computational capability and cost. Consider the 23x23 package size for board space constraints and verify peripheral requirements such as USB 3.0 and Ethernet interface counts against the available pinout.

Microprocessors Part Context

This part belongs to the NXP QorIQ Layerscape LS1023A series, designed for small-scale networks and industrial automation. It shares architectural similarities with the quad-core LS1043A but provides a dual-core solution optimized for BOM cost reduction. The processor supports flexible I/O configurations suitable for fanless designs.

Microprocessors Replacement Considerations

Pin-compatible alternatives within the same package include other variants of the LS1023A and LS1043A families. Verify core count, clock speed, and operating temperature specifications when substituting.
