Product details
Overview
LS1027AXN7PQA from NXP Semiconductors is a dual-core 64-bit ARM Cortex-A72 system-on-chip (SoC) designed for industrial gateways and TSN-enabled networking edge devices. It operates up to 1.5 GHz, integrates 1 MB ECC-protected L2 cache, DDR4/DDR3L memory controller with ECC, and features four SerDes lanes supporting PCIe 3.0, SATA 3, and multiple 2.5G/1G Ethernet interfaces.
For engineers reviewing the LS1027AXN7PQA datasheet, LS1027AXN7PQA pinout, LS1027AXN7PQA application, or LS1027AXN7PQA equivalent, key selection criteria include TSN-capable Ethernet switch support, dual 2.5G-SGMII + RGMII + 10G-SXGMII interface flexibility, Arm TrustZone security, and FC-PBGA 448-ball package compatibility with industrial thermal and power sequencing requirements.
Technical Context
The LS1027AXN7PQA implements a Cache Coherent Interconnect (CCI-400) at up to 400 MHz to maintain coherency between its two Cortex-A72 cores, each with 48KB L1 instruction and 32KB L1 data caches (ECC-protected). The shared 1MB L2 cache enables deterministic inter-core communication essential for real-time industrial control tasks.
Its high-speed interface subsystem includes four SerDes lanes configured for mixed-mode operation: two PCIe 3.0 controllers, one SATA 6 Gbit/s controller, and flexible SGMII/QSGMII/USXGMII PHYs supporting up to four 2.5G Ethernet switch ports or one 10G-SXGMII port with TSN timing precision per IEEE 1588 and 1722 standards.

Equivalent & Alternatives
The following parts are listed as comparable options for similar SoC-based networking applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP LS1043AXE7QQB | Quad-core Cortex-A53, no Cortex-A72; higher core count but lower per-core performance and no 2.5G/10G SerDes support. | Better suited for control-plane-heavy routing with less demanding real-time latency; lacks TSN hardware acceleration. | Select when prioritizing software-defined networking throughput over sub-100 µs deterministic switching. |
| Microchip SAMA7G54-CU | Single-core Cortex-A7, no TSN switch, no PCIe/SATA, limited SerDes (only 1×Gigabit Ethernet PHY). | Targeted at cost-sensitive HMI and basic gateway use cases; lacks hardware TSN, ECC memory, and multi-gigabit interfaces. | Select only for non-TSN, low-bandwidth edge node applications where BOM cost is primary constraint. |
