Product details
Overview
LS1023AXE8KQB 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 LS1023AXE8KQB datasheet, LS1023AXE8KQB pinout, LS1023AXE8KQB application, or LS1023AXE8KQB equivalent, key selection criteria include its dual-core 64-bit ARM architecture, integrated Frame Manager for hardware packet parsing/classification, SEC 5.4 security engine, PCIe Gen 2.0 interfaces, and QUICC Engine support for legacy TDM/HDLC/PROFIBUS protocols.
Technical Context
The LS1023AXE8KQB implements two ARM Cortex-A53 64-bit cores clocked up to 1.2 GHz (not 1.6 GHz - confirmed per LS1023A datasheet), with 32 KB I-Cache and 32 KB D-Cache per core and a shared 1 MB L2 cache. It uses CoreLink CCI-400 for cache coherency and includes an SMMU for I/O virtualization support.
Networking is handled by a hardware-accelerated Frame Manager supporting up to six Gigabit Ethernet ports with IEEE 1588v2 timestamping, integrated DPAA for classification/policing/reassembly, and SEC 5.4 for inline IPsec/SSL/DTLS acceleration. The 4-lane multi-protocol SerDes supports PCIe Gen 2.0 (x1/x2/x4), SATA 3.0, and SGMII/XFI.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Cores | Dual ARM Cortex-A53 64-bit cores, up to 1.2 GHz - enables deterministic real-time control while maintaining Linux application compatibility. |
| L2 Cache | 1 MB unified L2 cache - reduces memory bandwidth pressure and improves throughput for packet-intensive workloads. |
| Memory Interface | 32-bit DDR3L/DDR4 controller - supports low-power DDR3L and higher-bandwidth DDR4 for BOM-optimized, cost-sensitive designs. |
| Ethernet Ports | Up to 6 × 1 GbE with IEEE 1588v2 - enables precise time-synchronized industrial control and telecom timing applications. |
| Security Engine | SEC 5.4 with IPsec/SSL/DTLS acceleration - offloads crypto processing to achieve line-rate encrypted traffic without CPU saturation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar communications processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LS1043AXE8KQB | Quad-core ARM Cortex-A53, 1.6 GHz max, 1 MB L2 - higher compute density but +1.5 W typical power vs. LS1023AXE8KQB. | Better suited for multi-VNF vCPE and deep packet inspection where core count outweighs power budget constraints. | Select LS1043AXE8KQB when >2 Gb/s per-core forwarding or >4 concurrent VNFs are required. |
| i.MX8M Plus | Quad-core Cortex-A53 + NPU, no QUICC Engine, no Frame Manager - lacks hardware packet acceleration and legacy protocol support. | Targeted at multimedia-rich HMI and AI inference at edge, not packet-forwarding or industrial protocol bridging. | Choose i.MX8M Plus only if vision/AI workload dominates and networking is secondary or handled externally. |
Compared with LS1043AXE8KQB and i.MX8M Plus, the LS1023AXE8KQB uniquely balances dual-core determinism, DPAA offload efficiency, and QUICC Engine legacy I/O - making it optimal for cost-constrained, thermally limited industrial gateways requiring both real-time control and secure IP connectivity.

How many Gigabit Ethernet ports does the LS1023AXE8KQB support?
The LS1023AXE8KQB supports up to six Gigabit Ethernet ports via its integrated 4-lane SerDes, configured as SGMII, QSGMII, or 2.5G-overclocked SGMII. All ports include IEEE 1588v2 hardware timestamping and are managed by the Frame Manager for classification, policing, and reassembly - no external switch fabric is required for 6-port routing.
Is the QUICC Engine present in the LS1023AXE8KQB?
Yes, the LS1023AXE8KQB includes a fully integrated QUICC Engine subsystem. It provides independent HDLC, TDM, and PROFIBUS protocol handling with dedicated DMA and microcode programmability - enabling glueless connectivity to legacy industrial fieldbus networks without external protocol ICs or FPGA logic.
