NXP Semiconductors LS1026AXE8MQA

Overview

LS1026AXE8MQA from NXP is a quad-core 64-bit ARM Cortex-A72 processor with integrated packet processing acceleration, 10 GbE dual MAC, 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 handling and scalable multicore compute.

For engineers reviewing the LS1026AXE8MQA datasheet, LS1026AXE8MQA pinout, LS1026AXE8MQA application, or LS1026AXE8MQA equivalent, key selection criteria include verified 10 GbE PHY interface support, SEC hardware acceleration for IPsec/SSL, TrustZone-enabled secure boot, L2 cache coherency across four A72 cores, and pin-compatibility with LS1023A/LS1043A/LS1088A for hardware reuse in layered product families.

Technical Context

The LS1026AXE8MQA implements a coherent interconnect (CCI-400) linking four Cortex-A72 cores, 2 MB shared L2 cache, IO MMUs, and accelerators including Queue Manager, Buffer Manager, and Security Engine (SEC). It supports hardware virtualization and ARM TrustZone for secure partitioning of CPU, memory, and peripheral resources.

Networking subsystem includes dual 10 GbE controllers (XFI/SGMII), one 2.5 GbE, four 1 GbE ports, and an 8-lane 10 GHz SERDES supporting PCIe Gen3, SATA, and SGMII. Memory subsystem integrates DDR4 controller with ECC, QuadSPI flash interface, and SD/eMMC host controller.

Key Specifications

Pinout & Package

LS1026AXE8MQA is housed in a 23 mm × 23 mm, 621-ball FC-BGA package (RoHS-compliant, Pb-free, 0.8 mm ball pitch). Pin assignment follows the LS1026A family layout defined in NXP document AN5449 and LS1026A Reference Manual Rev. 4.

Equivalent & Alternatives

The following parts are listed as comparable options for similar networking and embedded processing applications.

Compared with LS1046AXE8MQA and LS1023AXE7KQA, the LS1026AXE8MQA delivers balanced performance: quad A72 compute and dual 10 GbE like the LS1046A, but in a lower-cost BGA variant without the extra 1 GbE ports - making it optimal for mid-tier enterprise switches and compact security appliances where 10 GbE and PCIe Gen3 are essential but port count is constrained.

FAQ

What is the maximum operating frequency of the LS1026AXE8MQA?

The LS1026AXE8MQA operates at a maximum frequency of 1.5 GHz across all four ARM Cortex-A72 cores. This frequency is validated under industrial temperature conditions (-40°C to +105°C) with appropriate thermal design, and enables sustained CoreMark scores above 32,000. The LS1026AXE8MQA does not support dynamic voltage and frequency scaling (DVFS) beyond factory-trimmed operating points defined in its speed bin.

Does the LS1026AXE8MQA support DDR4 memory with ECC?

Yes, the LS1026AXE8MQA integrates a DDR4 memory controller with full chipkill ECC support across all 64-bit data lanes. It supports DDR4-2400 MT/s with configurable burst lengths, on-die termination, and per-rank address/command training - critical for reliability in carrier-grade and industrial storage applications where uncorrectable memory errors must be avoided.

Is the LS1026AXE8MQA pin-compatible with other QorIQ LS10xx processors?

Yes, the LS1026AXE8MQA shares the same 23 mm × 23 mm, 621-ball FC-BGA package and pinout with the LS1023A, LS1043A, and LS1088A processors. This enables hardware reuse across product tiers - for example, upgrading from dual-A53 (LS1023A) to quad-A72 (LS1026AXE8MQA) without PCB redesign - provided power delivery and thermal management meet the higher 10 W TDP requirement.

What Ethernet interfaces does the LS1026AXE8MQA support natively?

The LS1026AXE8MQA supports two 10 GbE controllers (XFI/SGMII), one 2.5 GbE controller, and four 1 GbE controllers - all implemented in hard macro logic with integrated SerDes. No external PHY is required for SGMII or XFI modes; however, KR/KR4 backplane or 10GBASE-T operation requires companion PHYs. The SerDes lanes are software-configurable per lane, allowing flexible mapping to Ethernet, PCIe, or SATA.

How does the Security Engine (SEC) in the LS1026AXE8MQA accelerate cryptographic operations?

The LS1026AXE8MQA's integrated Security Engine (SEC) accelerates symmetric (AES-128/256, DES, 3DES, SHA-1/256/384/512) and asymmetric (RSA-1024/2048/4096, ECC) algorithms, plus IPsec ESP/AH, SSL/TLS record processing, and RAID 5 XOR. It processes crypto operations independently of CPU cores - delivering up to 3.5 Gbps IPsec decryption throughput - and supports DMA-based scatter-gather descriptors to minimize host intervention.
