NXP Semiconductors LS1018ASE7PQA

Overview

LS1018ASE7PQA 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, and 1MB shared L2 cache with ECC. It integrates a DDR3L/DDR4 memory controller (1.6 GT/s), TSN-capable Ethernet switch, dual CAN-FD modules, and DisplayPort 1.3/eDP 1.4 support for 4Kp60 displays - deployed in industrial gateways and edge networking equipment.

For engineers reviewing the LS1018ASE7PQA datasheet, LS1018ASE7PQA pinout, LS1018ASE7PQA application, or LS1018ASE7PQA equivalent, key selection considerations include its FC-PBGA 448-ball package, single A72 core configuration (vs. dual-core LS1028A), SerDes-based 2.5G/1G Ethernet interfaces with IEEE 1588/TSN support, and integrated graphics GPU (10.4 GFLOPS, OpenGL ES 3.0).

Technical Context

The LS1018ASE7PQA implements a Cache Coherent Interconnect (CCI-400) running at up to 400 MHz to maintain coherency between its single Cortex-A72 core and on-chip peripherals. Its memory subsystem includes a 32-bit DDR3L/DDR4 controller with full ECC protection across L1/L2 caches and DRAM interface.

Networking functionality is delivered via a hardware-accelerated TSN switch with four external ports, an ENETC Ethernet controller supporting RGMII and SerDes-based 1G/2.5G interfaces with IEEE 1588v2 and TSN timing, and four SerDes lanes configurable for PCIe 3.0, SATA 3, SGMII, QSGMII, or USXGMII protocols.

Key Specifications

Pinout & Package

FAQ

What is the maximum DDR4 data rate supported by LS1018ASE7PQA?

The LS1018ASE7PQA supports DDR4 memory at up to 1.6 GT/s, corresponding to DDR4-3200 effective data rate with a 1600 MHz clock. This is confirmed in Section 3.9 of the LS1028A/LS1018A datasheet Rev. 0 (December 2019), which specifies AC timing parameters for both DDR3L and DDR4 modes under recommended operating conditions. LS1018ASE7PQA maintains full compatibility with this specification.

Does LS1018ASE7PQA support PCIe 3.0, and how many lanes are available?

Yes, LS1018ASE7PQA supports two PCIe 3.0 controllers via its four SerDes lanes - each controller can operate as a x1 or x2 link. This capability is explicitly documented in the "Four SerDes lanes" section of the datasheet, and the LS1018A block diagram (Figure 2) confirms PCIe 3.0 integration. No external retimer is required for standard x1 endpoint connections.

Is LS1018ASE7PQA pin-compatible with LS1028ASE7PQA?

Yes, LS1018ASE7PQA and LS1028ASE7PQA share identical FC-PBGA 448-ball packaging, mechanical dimensions (17 mm × 17 mm), and pinout mapping - verified through the unified pin assignment tables in the LS1028A/LS1018A datasheet. This allows PCB reuse between single-core and dual-core variants, simplifying platform scalability.

What display interfaces does LS1018ASE7PQA support, and what resolutions are achievable?

LS1018ASE7PQA integrates a DisplayPort 1.3 and eDP 1.4 PHY supporting HBR2 link rate (5.4 Gbit/s), enabling native 4Kp60 (3840×2160 @ 60 Hz) output. The LCD controller and GPU pipeline are validated for this resolution in the multimedia section of the datasheet, with no external timing controller required for direct panel connection.

How is security implemented in LS1018ASE7PQA for secure boot and runtime protection?

LS1018ASE7PQA implements security via Arm TrustZone for hardware-enforced memory isolation, a dedicated Security Engine for cryptographic acceleration (AES-128/256, SHA-256, RSA), and one-time programmable (OTP) fuses for immutable root-of-trust. Secure Boot verifies signed bootloader images before execution, and runtime protection leverages TrustZone to isolate secure world services from the normal world Linux OS - all detailed in Sections 1 and 7 of the datasheet.
