NXP Semiconductors LS1026ASN8P1A

Overview

LS1026ASN8P1A from NXP is a quad-core 64-bit ARM Cortex-A72 processor with integrated packet processing acceleration, 10 GbE dual-port MACs, PCIe Gen3 (x4/x2/x1), SATA 3.0, USB 3.0, and DDR4 memory controller - deployed in enterprise routers, network-attached storage, and security appliances requiring deterministic low-latency packet forwarding and hardware-accelerated crypto.

For engineers reviewing the LS1026ASN8P1A datasheet, LS1026ASN8P1A pinout, LS1026ASN8P1A application, or LS1026ASN8P1A equivalent, key selection criteria include verified 10 GbE PHY interface support, SEC engine throughput for IPsec/SSL offload, L2 cache coherency across four A72 cores, and pin-compatibility with LS1023A/LS1043A for scalable hardware reuse.

Technical Context

The LS1026ASN8P1A implements a CCI-400 coherent interconnect linking four Cortex-A72 cores sharing 2 MB L2 cache, with dedicated hardware accelerators for packet parsing/classification/distribution, queue management, and buffer management - enabling line-rate 10 GbE forwarding without CPU intervention. It integrates an I/O MMU per PCIe root complex and supports ARM TrustZone for secure boot and tamper-resistant key storage.

Its 8-lane 10 GHz SERDES fabric delivers two 10 GbE SFI/XFI interfaces, one 2.5 GbE, four 1 GbE RGMII/SGMII ports, three PCIe Gen3 controllers (x4/x2/x1), and a SATA 3.0 host controller - all managed via a unified clocking and power management subsystem compliant with ARM's PSCI specification.

FAQ

What is the maximum operating frequency of the LS1026ASN8P1A?

The LS1026ASN8P1A operates at a maximum frequency of 1.4 GHz across all four ARM Cortex-A72 cores. This frequency is thermally validated for convection-cooled environments and supported by the integrated dynamic voltage and frequency scaling (DVFS) controller. The LS1026ASN8P1A maintains full feature functionality-including dual 10 GbE, PCIe Gen3, and SEC acceleration-at this rated speed without derating.

Does the LS1026ASN8P1A support DDR4 memory with ECC?

Yes, the LS1026ASN8P1A supports DDR4-2400 memory with chipkill-level ECC correction across its 64-bit bus. The memory controller implements address parity, data ECC (SEC-DED), and scrubbing logic, enabling detection and correction of single-bit errors and detection of multi-bit errors - critical for carrier-grade and industrial control applications requiring >99.999% uptime.

Is the LS1026ASN8P1A pin-compatible with the LS1043A processor?

Yes, the LS1026ASN8P1A shares identical ball mapping and package dimensions (23 mm × 23 mm FC-BGA) with the LS1043A. This enables direct PCB reuse for hardware upgrades from quad-A53 to quad-A72 performance tiers, preserving DDR4, PCIe, and Ethernet routing - provided thermal and power delivery margins accommodate the higher LS1026ASN8P1A TDP of 9.5 W.

What Ethernet PHY interfaces does the LS1026ASN8P1A natively support?

The LS1026ASN8P1A integrates native support for 2 × 10 GbE (XFI/SFI), 1 × 2.5 GbE (USXGMII), and 4 × 1 GbE (RGMII/SGMII) PHY interfaces. It does not include internal 10GBASE-T PHYs; external PHYs such as the AQR113C or Aquantia AQC113 are required for copper-based 10 GbE. All interfaces comply with IEEE 802.3 standards and support IEEE 1588v2 timestamping.

Can the LS1026ASN8P1A run real-time operating systems like VxWorks or FreeRTOS?

Yes, the LS1026ASN8P1A supports VxWorks 7 and FreeRTOS via NXP's validated BSPs and ARMv8-A hypervisor extensions. Its TrustZone isolation, deterministic interrupt latency (<1 µs), and cache-coherent interconnect allow hard real-time tasks to execute in secure world while Linux runs in normal world - enabling mixed-criticality deployments in industrial control and avionics edge gateways.
