Product details
Overview
LS1023AXN8PQB 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, 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 - deployed in vCPE, IoT gateways, and industrial PLCs.
For engineers reviewing the LS1023AXN8PQB datasheet, LS1023AXN8PQB pinout, LS1023AXN8PQB application, or LS1023AXN8PQB equivalent, key selection criteria include dual-core 64-bit ARM performance per watt, integrated Frame Manager for hardware-accelerated packet parsing/classification, SEC 5.4 for IPsec offload, PCIe Gen2 x3, USB 3.0 x3, and QUICC Engine support for legacy TDM/HDLC/PROFIBUS protocols.
Technical Context
The LS1023AXN8PQB implements two 64-bit ARM Cortex-A53 cores clocked up to 1.2 GHz (not 1.6 GHz - confirmed for LS1023A family), backed by a unified 1 MB L2 cache and CoreLink CCI-400 coherent interconnect with SMMU for I/O virtualization. It uses the QorIQ Data Path Acceleration Architecture (DPAA) with Frame Manager for hardware-based packet classification, distribution, and policing.
Networking is enabled via a 4-lane 10 GHz multi-protocol SerDes supporting up to six 1 GbE ports (with IEEE 1588v2), three PCIe Gen2 interfaces, one SATA 3.0 controller, and triple USB 3.0 with integrated PHY. Security acceleration is handled by SEC 5.4 supporting IPsec, SSL/TLS, DTLS, IKE, and XOR for RAID 5.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Cores | 2× 64-bit ARM Cortex-A53 @ up to 1.2 GHz - enables deterministic real-time control with low-power operation suitable for fanless edge deployments. |
| L2 Cache | 1 MB unified - reduces memory bandwidth pressure and improves instruction/data hit rates for network stack and control plane tasks. |
| Memory Interface | 32-bit DDR3L/DDR4 controller - supports cost-optimized BOM with single-rank DDR4-2133 or DDR3L-1600, enabling lower power and higher density than DDR3-only SoCs. |
