NXP Semiconductors LS1018AXN7PQA

Overview

LS1018AXN7PQA from NXP Semiconductors is a single-core 64-bit ARM Cortex-A72 system-on-chip (SoC) operating up to 1.5 GHz, featuring 48KB L1 instruction cache, 32KB L1 data cache with ECC, 1MB shared L2 cache, DDR4/DDR3L memory controller with ECC, and integrated TSN-capable Ethernet switch. It targets industrial gateways and edge networking equipment requiring deterministic timing and secure boot.

For engineers reviewing the LS1018AXN7PQA datasheet, LS1018AXN7PQA pinout, LS1018AXN7PQA application, or LS1018AXN7PQA equivalent, key selection considerations include its FC-PBGA 448-ball package, dual USB 3.0 controllers with PHY, four SerDes lanes supporting PCIe 3.0/SATA/SGMII/TSN Ethernet, and support for DisplayPort 1.3/eDP 1.4 up to 4Kp60 resolution.

Technical Context

The LS1018AXN7PQA implements a single ARM Cortex-A72 core with coherent interconnect (CCI-400) operating at up to 400 MHz, enabling cache coherency across subsystems. Its memory subsystem includes a 32-bit DDR3L/DDR4 controller supporting up to 1.6 GT/s with on-the-fly ECC correction for reliability-critical applications.

Networking functionality is delivered via a TSN-capable Ethernet switch with four external ports and an ENETC controller supporting RGMII and 1G/2.5G SerDes-based interfaces with IEEE 1588 and IEEE 1722 compliance. The SerDes block supports flexible configuration across PCIe 3.0, SATA 3, SGMII, QSGMII, USXGMII, and 1000Base-KX protocols.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of the LS1018AXN7PQA processor core?

The LS1018AXN7PQA features a single ARM Cortex-A72 core rated for operation up to 1.5 GHz under recommended thermal and voltage conditions. This frequency is achievable with proper PCB thermal design and 1.0 V ±3% core supply. The LS1018AXN7PQA datasheet specifies this as the absolute maximum sustained clock rate for continuous workload execution.

Does the LS1018AXN7PQA support DDR4 memory with ECC, and what is the maximum data rate?

Yes, the LS1018AXN7PQA integrates a 32-bit DDR3L/DDR4 memory controller with full on-the-fly ECC support for both data and address paths. It supports DDR4-1600 (1.6 GT/s), delivering up to 12.8 GB/s peak bandwidth. The LS1018AXN7PQA requires external DDR4 chips with x8 or x16 organization and appropriate termination for stable operation.

How many SerDes lanes does the LS1018AXN7PQA provide, and what protocols can they be configured for?

The LS1018AXN7PQA provides four configurable SerDes lanes. These can be allocated as two PCIe 3.0 x1 links, one SATA 6 Gbit/s controller, up to four SGMII interfaces (1 Gbps each), up to one 2.5G-SGMII, one QSGMII (four 1 Gbps ports), or USXGMII (10G-SXGMII/QXGMII). Configuration is done via RCW (Reset Configuration Word) fuses at boot.

Is the LS1018AXN7PQA pin-compatible with the LS1028AXN7PQA, and what are the key functional differences?

No, the LS1018AXN7PQA is not pin-compatible with the LS1028AXN7PQA despite sharing the same FC-PBGA 448 package footprint. Key differences include LS1018AXN7PQA's single Cortex-A72 core (vs. dual), integrated 3D GPU and DP/eDP controller (absent in LS1028A), and reduced SerDes lane allocation. Pin functions differ significantly in DDR, SerDes, and display banks.

What security features are implemented in hardware on the LS1018AXN7PQA?

The LS1018AXN7PQA includes Arm TrustZone for hardware-enforced memory isolation, a ROM-based secure boot chain verifying signed firmware with SHA-256/RSA-2048, and a dedicated Security Engine supporting AES-128/256, SHA-256, and RSA-2048 acceleration. These features are active by default and require no external security ICs - a core requirement for the LS1018AXN7PQA's target industrial and medical applications.
