LS1048ASN7PTA

Microprocessors Overview

The LS1048ASN7PTA is a QorIQ LS10x8A multicore communications processor featuring four ARM Cortex-A53 cores operating up to 1.6 GHz with 1 MB L2 cache. It integrates DPAA2 architecture, an Advanced I/O Processor (AIOP), and a Security Engine (SEC). Networking interfaces include two 1/10 GbE ports and eight 1 GbE ports. Connectivity features comprise three PCIe 3.0 controllers, one SATA 3.0 controller, and two USB 3.0 ports with PHYs. The device supports DDR4 memory via a 64-bit controller and utilizes an FCBGA package.

• Provides hardware virtualization support with SMMUs and partitioning enforcement capabilities.
• Features integrated security engines supporting secure boot and TrustZone technology.

Microprocessors Applications

• Intelligent edge access
• Network Function Virtualization (NFV) solutions
• Wireless access point control
• Virtual Customer Premise Equipment (vCPE)
• Industrial applications

Microprocessors Procurement Notes

Verify the specific ordering suffix against official NXP documentation to confirm pin compatibility and software support requirements. Ensure the selected variant matches the required core count and cache configuration for the target application. Cross-reference the datasheet revision history for any updates regarding errata or recommended operating conditions prior to finalizing procurement specifications.

Microprocessors Selection Notes

Select this processor when high-performance packet processing is required alongside general-purpose computing. The inclusion of the AIOP allows for significant CPU load reduction by handling complex lookups and encryption autonomously. Consider the LS1048A over the LS1088A if only four cores are sufficient, as it offers a cost-effective solution while maintaining full DPAA2 feature parity and software compatibility within the Layerscape ecosystem.

Microprocessors Part Context

This component belongs to the QorIQ LS10x8A family, which also includes the LS1088A, LS1084A, and LS1044A. These processors share the same underlying architecture and software toolkit but differ in core counts and cache sizes. The LS1048A provides a balanced performance tier suitable for applications requiring robust networking capabilities without the need for the maximum eight-core configuration found in the top-tier LS1088A.

Microprocessors Replacement Considerations

The LS1048A is pin-compatible with the LS1023A, LS1043A, and LS1088A SoCs, allowing for potential hardware design reuse across different performance tiers within the Layerscape portfolio. Verify software BSP compatibility when migrating between these variants to ensure proper driver initialization for the specific core and cache configurations.
