Product details
Overview
LS1027ASN7PQA from NXP Semiconductors is a dual-core 64-bit ARM Cortex-A72 system-on-chip (SoC) operating up to 1.5 GHz, featuring 1 MB ECC-protected L2 cache, DDR4/DDR3L memory controller with ECC, and integrated TSN-capable Ethernet switch. It serves as the central processing and networking engine in industrial gateways and time-sensitive networking edge devices.
For engineers reviewing the LS1027ASN7PQA datasheet, LS1027ASN7PQA pinout, LS1027ASN7PQA application, or LS1027ASN7PQA equivalent, key selection criteria include its dual A72 core performance, 2.5G TSN Ethernet support, PCIe 3.0 x2 connectivity, CAN FD interfaces, and FC-PBGA 448-ball package thermal and layout constraints.
Technical Context
The LS1027ASN7PQA implements a coherent dual-core ARM Cortex-A72 cluster sharing a unified 1 MB L2 cache with ECC, connected via Cache Coherent Interconnect (CCI-400) running at up to 400 MHz. Its SerDes subsystem supports four lanes configurable as PCIe 3.0, SATA 3, SGMII, QSGMII, or USXGMII - enabling flexible high-speed peripheral integration without external switches.
It integrates a TSN-capable Ethernet switch with four external ports and an ENETC controller supporting IEEE 1588 v2 and 1722, alongside two CAN FD modules, eight I²C controllers, six LPUARTs, and dual USB 3.0 controllers with integrated PHY - all managed under Arm TrustZone®-enabled secure boot and runtime isolation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance industrial SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LS1043ASN7QQB | Quad-core Cortex-A53, 1.6 GHz, no Cortex-A72; adds SEC crypto accelerator but lacks TSN switch. | Better for crypto-heavy firewall/routing workloads; unsuitable for sub-ms TSN determinism. | Select when cryptographic throughput > real-time Ethernet determinism; verify PCIe lane allocation differs (4×1 vs 2×2). |
| LS1028ASN7PQA | Same dual A72 core, identical pinout and package, but adds 10G-SXGMII and enhanced security fusing. | Required for 10G uplink aggregation or FIPS 140-2 Level 3 certified deployments. | Drop-in replacement if 10G or certified secure boot is needed; otherwise LS1027ASN7PQA offers cost advantage. |
Compared with LS1043ASN7QQB, LS1027ASN7PQA delivers superior single-thread latency and native TSN switching, while LS1028ASN7PQA extends it with 10G capability and hardened security - making LS1027ASN7PQA the optimal balance of determinism, integration, and BOM cost for 2.5G industrial edge nodes.

FAQ
What is the maximum DDR4 data rate supported by LS1027ASN7PQA?
The LS1027ASN7PQA supports DDR4 memory operation up to 1.6 GT/s, corresponding to DDR4-3200 data rates with appropriate signal integrity design. This enables sustained bandwidth exceeding 25 GB/s for memory-intensive industrial control and packet buffering tasks within the LS1027ASN7PQA platform.
Does LS1027ASN7PQA include hardware support for IEEE 1588 Precision Time Protocol?
Yes, LS1027ASN7PQA integrates full hardware IEEE 1588 v2 support in both its TSN switch and ENETC controller, including timestamping at the PHY interface level, transparent clock functionality, and hardware-assisted best master clock algorithm - essential for sub-microsecond time synchronization in LS1027ASN7PQA-based industrial systems.
Can LS1027ASN7PQA operate in extended temperature ranges for industrial deployment?
Yes, LS1027ASN7PQA is rated for operation from –40°C to +105°C junction temperature, validated per industrial thermal specifications. Its integrated Thermal Monitor Unit (TMU) provides calibrated on-die temperature sensing, enabling robust thermal management in fanless enclosures where LS1027ASN7PQA serves as the primary compute node.
How many PCIe 3.0 lanes does LS1027ASN7PQA provide, and are they configurable?
LS1027ASN7PQA provides two independent PCIe 3.0 controllers, each supporting ×1 or ×2 link widths, totaling four SerDes lanes. These lanes are software-configurable via RCW settings to operate as PCIe 3.0 ×2, SATA 3, or SGMII - allowing flexible high-speed interface allocation without hardware redesign of the LS1027ASN7PQA carrier board.
Is LS1027ASN7PQA pin-compatible with other LS102xA family members?
LS1027ASN7PQA shares the same FC-PBGA 448-ball package and pinout with LS1028ASN7PQA, enabling mechanical and PCB layout compatibility. However, LS1027ASN7PQA lacks the 10G-SXGMII and enhanced security fusing present in LS1028ASN7PQA - requiring firmware and schematic validation before substitution in LS1027ASN7PQA designs.
