Product details
Overview
LS1023AXN8KQB from NXP Semiconductors is a dual-core, 64-bit ARM Cortex-A53 communications processor designed for fanless industrial and edge networking applications. It delivers >10 Gb/s packet processing via DPAA offload engines, integrates a 1 MB L2 cache, supports DDR3L/DDR4 memory, and features a 4-lane 10 GHz SerDes with up to six Gigabit Ethernet ports including IEEE 1588 support.
For engineers reviewing the LS1023AXN8KQB datasheet, LS1023AXN8KQB pinout, LS1023AXN8KQB application, or LS1023AXN8KQB equivalent, key selection considerations include its dual-core 64-bit ARM architecture, integrated Frame Manager for hardware packet parsing/classification, SEC 5.4 security engine, PCIe Gen 2, USB 3.0, and QUICC Engine support for legacy TDM/HDLC/PROFIBUS protocols.
Technical Context
The LS1023AXN8KQB implements two 64-bit ARM Cortex-A53 cores clocked up to 1.2 GHz (per core), backed by a unified 1 MB L2 cache and CoreLink CCI-400 coherent interconnect with SMMU for I/O virtualization. Its Data Path Acceleration Architecture (DPAA) includes Frame Manager, Queue Manager, and Buffer Manager to offload packet classification, distribution, and policing from CPU cores.
Networking is enabled through a 4-lane multi-protocol SerDes supporting up to six 1 GbE interfaces with IEEE 1588 v2 timestamping, three PCIe Gen 2 controllers, one SATA 3.0 port, triple USB 3.0 with integrated PHY, QuadSPI, IFC, SD/eMMC, and uQE for legacy protocol handling (HDLC/TDM/PROFIBUS).

FAQ
What is the maximum operating frequency of the LS1023AXN8KQB?
The LS1023AXN8KQB operates at up to 1.2 GHz per ARM Cortex-A53 core. This frequency is guaranteed across the commercial temperature range (0°C to 105°C junction) under specified voltage and cooling conditions. Frequency scaling is managed via dynamic voltage and frequency scaling (DVFS) controlled by the ARM PSCI interface, and the LS1023AXN8KQB supports multiple OPP (Operating Performance Points) defined in its device tree bindings.
Does the LS1023AXN8KQB support DDR4 memory?
Yes, the LS1023AXN8KQB supports both DDR3L and DDR4 memory interfaces. It implements a 32-bit DDR controller compliant with JEDEC DDR4-2133 and DDR3L-1866 standards. DDR4 support enables higher density, lower voltage (1.2 V), and improved bandwidth efficiency - critical for extending memory lifetime in industrial deployments where thermal cycling is severe.
How many PCIe Gen 2 lanes does the LS1023AXN8KQB provide?
The LS1023AXN8KQB provides three independent PCIe Gen 2.0 lanes, each configurable as a separate x1 link. These lanes support endpoint and root complex modes, ASPM L0s/L1 power states, and MSI/MSI-X interrupt delivery. They are commonly used to connect Wi-Fi 5 modules, SATA controllers, or FPGA-based acceleration cards in compact edge systems using the LS1023AXN8KQB.
Is the QUICC Engine present in the LS1023AXN8KQB?
Yes, the LS1023AXN8KQB includes the QUICC Engine (uQE), a dedicated RISC coprocessor supporting HDLC, TDM, and PROFIBUS protocols without CPU intervention. The uQE has its own instruction RAM, data RAM, and DMA channels, and is accessible via memory-mapped registers. This enables seamless integration with legacy industrial fieldbus infrastructure - a key differentiator versus generic ARM SoCs.
What security features are integrated into the LS1023AXN8KQB?
The LS1023AXN8KQB integrates TrustZone-enabled secure boot, an SMMU for I/O memory protection, and the Security Engine (SEC) 5.4. SEC 5.4 accelerates symmetric (AES-GCM, DES/3DES), asymmetric (RSA-2048, ECC-256), and hash (SHA-1/256) operations. It supports inline IPsec ESP/AH processing and TLS 1.2 record encryption, enabling end-to-end data confidentiality in LS1023AXN8KQB-based gateways without software crypto overhead.
