NXP Semiconductors LS1017ASE7PQA

Overview

LS1017ASE7PQA from NXP Semiconductors is a single-core, 64-bit ARM Cortex-A72 system-on-chip (SoC) designed for industrial gateways and edge networking. It operates up to 1.5 GHz, integrates 48KB L1 instruction cache and 32KB L1 data cache with ECC, features a 1MB shared L2 cache, and supports DDR3L/DDR4 memory with ECC at up to 1.6 GT/s.

For engineers reviewing the LS1017ASE7PQA datasheet, LS1017ASE7PQA pinout, LS1017ASE7PQA application, or LS1017ASE7PQA equivalent, this page delivers verified core architecture, SerDes interface capabilities (PCIe 3.0, SATA 3, SGMII, TSN Ethernet), peripheral integration (dual CAN-FD, eSDHC, USB 3.0, FlexSPI), and FC-PBGA-448 package details essential for hardware design and BOM validation.

Technical Context

The LS1017ASE7PQA implements a single ARM Cortex-A72 core with coherent interconnect (CCI-400) operating up to 400 MHz, enabling cache coherency between CPU and subsystems. Its memory subsystem includes a 32-bit DDR3L/DDR4 controller with on-the-fly ECC support and configurable timing for industrial reliability.

High-speed I/O is managed via four SerDes lanes supporting PCIe 3.0 x2, SATA 3, up to four SGMII ports at 1 Gbps, one 2.5G-SGMII port, and TSN-capable Ethernet Switch with RGMII and SerDes-based 1G/2.5G interfaces - all mapped to dedicated physical pins in the FC-PBGA-448 package.

Key Specifications

Pinout & Package

LS1017ASE7PQA uses a 448-ball Fine-Pitch Ceramic Ball Grid Array (FC-PBGA) package measuring 17 mm × 17 mm with 0.8 mm ball pitch. Pin functions are organized across DDR, SerDes, I²C, eSDHC, FlexSPI, UART, CAN, JTAG, and power domains as defined in the official NXP LS1027A/LS1017A datasheet Rev. 0 (Dec 2019).

FAQ

What is the maximum operating frequency of the LS1017ASE7PQA?

The LS1017ASE7PQA features a single ARM Cortex-A72 core rated for operation up to 1.5 GHz under specified thermal and voltage conditions per the NXP LS1027A/LS1017A datasheet Rev. 0. This frequency is achievable with proper board-level thermal management and stable 0.85 V ±3% core supply. The LS1017ASE7PQA does not support dynamic frequency scaling beyond this limit, and sustained operation above 1.5 GHz violates electrical specifications.

Does the LS1017ASE7PQA support DDR4 memory with ECC?

Yes, the LS1017ASE7PQA includes a 32-bit DDR3L/DDR4 memory controller with on-the-fly ECC generation and correction for both data and ECC bits. It supports DDR4-1600 (1.6 GT/s) with 16/32-bit data bus configurations and requires external x8 or x16 DDR4 components with appropriate ECC lane allocation. The LS1017ASE7PQA validates ECC functionality during boot and reports correctable/uncorrectable errors via its memory controller registers.

How many independent Ethernet interfaces does the LS1017ASE7PQA provide?

The LS1017ASE7PQA provides two distinct Ethernet subsystems: a four-port TSN-capable Ethernet switch with external PHY interface support, and a separate ENETC (Ethernet Controller) with RGMII and SerDes-based 1G/2.5G interfaces. These operate independently - the switch handles layer-2 forwarding and time-aware scheduling, while ENETC supports layer-3 routing and IEEE 1588 timestamping. Both are accessible simultaneously in Linux via separate network interfaces (e.g., sw0 and enetc0).

Is the LS1017ASE7PQA pin-compatible with the LS1027ASE7PQA?

Yes, the LS1017ASE7PQA and LS1027ASE7PQA share identical FC-PBGA-448 packaging, mechanical dimensions, thermal pad layout, and full pin-to-pin compatibility. All signal names, power domains, and ball assignments match exactly per the NXP LS1027A/LS1017A datasheet. This allows direct substitution in existing designs - though software must be adapted for the dual-core LS1027A's SMP requirements and higher power consumption.

What security features are implemented in hardware on the LS1017ASE7PQA?

The LS1017ASE7PQA integrates ARM TrustZone, a hardware-based security extension that partitions memory and peripherals into secure and non-secure worlds. It also includes a dedicated Security Engine supporting AES-128/256, SHA-256, and RSA-2048 acceleration, plus immutable ROM-based secure boot enforcing cryptographic signature verification of boot images. These features are active by default and do not require external secure elements - the LS1017ASE7PQA uses them to protect firmware updates, key storage, and runtime attestation.
