NXP Semiconductors LS1018AXE7PQA

Overview

LS1018AXE7PQA from NXP Semiconductors is a single-core, 64-bit ARM Cortex-A72 system-on-chip (SoC) designed for industrial gateways and TSN-enabled edge networking. It operates up to 1.5 GHz, integrates 48KB L1 instruction and 32KB L1 data cache with ECC, shares 1MB L2 cache, supports DDR4/DDR3L memory at 1.6 GT/s with ECC, and delivers deterministic low-latency Ethernet via TSN-capable switch and ENETC controller.

For engineers reviewing the LS1018AXE7PQA datasheet, LS1018AXE7PQA pinout, LS1018AXE7PQA application, or LS1018AXE7PQA equivalent, key selection considerations include its FC-PBGA 448-ball package, dual CAN-FD interfaces, 2.5G/1G TSN Ethernet support, DisplayPort 1.3/eDP 1.4 output, and hardware-accelerated security engine with Arm TrustZone®.

Technical Context

The LS1018AXE7PQA implements a single ARM Cortex-A72 core with coherent CCI-400 interconnect operating up to 400 MHz, enabling cache coherency between CPU, DMA, and peripherals. Its SerDes subsystem provides four lanes configurable as PCIe 3.0, SATA 6 Gbit/s, SGMII, 2.5G-SGMII, QSGMII, or USXGMII - supporting up to four 2.5G Ethernet switch ports or one 10G-SXGMII interface.

It integrates a TSN-capable Ethernet switch with four external ports and an ENETC controller featuring RGMII and 1G/2.5G SerDes-based TSN interfaces. The SoC includes dual eSDHC controllers compliant with SD 3.0, eMMC 4.4–5.1, two CAN-FD modules, eight I²C controllers, six LPUARTs, and a FlexSPI controller for high-speed flash interfacing.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of the LS1018AXE7PQA CPU core?

The LS1018AXE7PQA features a single ARM Cortex-A72 core rated for up to 1.5 GHz operation under recommended thermal and voltage conditions. This frequency is achievable with proper PCB thermal design and 1.0 V ±3% core supply. The LS1018AXE7PQA does not support dynamic frequency scaling beyond this rated maximum, and sustained operation above 1.5 GHz violates specifications and may cause instability or premature wear.

Does the LS1018AXE7PQA support DDR4 memory with ECC, and what is the maximum data rate?

Yes, the LS1018AXE7PQA integrates a 32-bit DDR3L/DDR4 SDRAM memory controller with full ECC support for both data and address parity. It supports DDR4-1600 (1.6 GT/s) operation with 64-byte burst lengths and configurable refresh rates. The LS1018AXE7PQA requires external DDR4 chips with x8 or x16 organization and on-die termination enabled for compliance with JEDEC JESD79-4.

How many TSN-capable Ethernet interfaces does the LS1018AXE7PQA provide, and what standards are supported?

The LS1018AXE7PQA integrates a 4-port TSN-capable Ethernet switch and a separate ENETC controller with RGMII and 1G/2.5G SerDes interfaces. It supports IEEE 802.1AS (time synchronization), 802.1Qbv (time-aware shaper), 802.1Qbu (frame preemption), and 802.1CB (stream reservation) in hardware. The LS1018AXE7PQA does not implement 802.1Qci (per-stream filtering and policing) in silicon and relies on software configuration for that function.

What display interfaces are integrated into the LS1018AXE7PQA, and what resolutions are supported?

The LS1018AXE7PQA includes a DisplayPort 1.3 and eDP 1.4 PHY with HBR2 (5.4 Gbit/s) link rate, supporting up to 4Kp60 (3840×2160@60 Hz) with 24-bit color depth and embedded audio. It also integrates a parallel RGB/LVDS LCD controller for legacy panel support. The LS1018AXE7PQA does not support HDMI or MIPI DSI natively and requires external level-shifting or bridge ICs for those interfaces.

Is the LS1018AXE7PQA pin-compatible with the LS1028AXE7PQA, and what are the key differences?

Yes, the LS1018AXE7PQA and LS1028AXE7PQA share identical FC-PBGA 448-ball packaging, pinout, power sequencing, and peripheral signal mapping. The primary difference is CPU configuration: LS1018AXE7PQA contains one Cortex-A72 core, while LS1028AXE7PQA contains two. All other subsystems-including DDR controller, SerDes, TSN switch, ENETC, eSDHC, CAN-FD, and security engine-are functionally identical and electrically compatible between the two parts.
