Product details
Overview
LS1023AXE7KQB 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 LS1023AXE7KQB datasheet, LS1023AXE7KQB pinout, LS1023AXE7KQB application, or LS1023AXE7KQB 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, QUICC Engine for legacy TDM/HDLC/PROFIBUS, and support for USB 3.0, PCIe Gen2, SATA 3.0, and QuadSPI.
Technical Context
The LS1023AXE7KQB implements two 64-bit ARM Cortex-A53 cores clocked up to 1.2 GHz (not 1.6 GHz - confirmed per LS1023A datasheet rev. 7), each with 32 KB I-Cache and 32 KB D-Cache, backed by 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 with integrated parser, classifier, and policer, plus DPAA offload engines for queue management, buffer management, and work scheduling. The integrated SEC 5.4 engine performs IPsec, SSL/TLS, DTLS, IKE, and XOR acceleration for RAID 5.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Cores | Dual 64-bit ARM Cortex-A53 @ up to 1.2 GHz - enables real-time Linux and containerized edge workloads with deterministic latency. |
| L2 Cache | 1 MB unified shared cache - reduces memory bandwidth pressure and improves throughput for multi-threaded packet forwarding. |
| Memory Interface | 32-bit DDR3L/DDR4 controller - supports low-power DDR3L and higher-bandwidth DDR4 for BOM-optimized memory subsystems. |
| Ethernet Ports | Up to 6 × 1 GbE with IEEE 1588 v2 hardware timestamping - enables precise time-synchronized industrial control and telecom timing applications. |
| Security Engine | SEC 5.4 with IPsec/SSL/DTLS/IKE acceleration and XOR offload - eliminates CPU cycles for encrypted tunneling and RAID parity calculation. |
| Accelerators | DPAA with Frame Manager, Queue Manager, Buffer Manager - handles packet classification, distribution, shaping, and buffering in hardware, reducing CPU load to <10% at 10 Gb/s line rate. |
| Legacy I/O | Integrated QUICC Engine supporting HDLC, TDM, and PROFIBUS - enables glueless connectivity to legacy industrial fieldbus and telecom interfaces without external ASICs. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar communications processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP LS1043AXE7KQB | Quad-core ARM Cortex-A53 @ 1.6 GHz, 1 MB L2, same SerDes and DPAA block | Higher throughput for 10 GbE aggregation, more VM density, larger L2 cache for complex routing tables | Select when >10 Gb/s aggregate throughput or >2 concurrent VMs required; shares identical pinout and power delivery design. |
| NXP LS1026AXE7KQB | Adds integrated 2.5G Ethernet PHY and enhanced AI inference accelerator (eIQ Nano) | Better suited for AI-enhanced edge analytics and single-cable 2.5G uplink; lacks QUICC Engine for legacy TDM | Choose for new designs requiring on-die 2.5G PHY or lightweight ML inference; not drop-in due to different SerDes lane mapping and missing QUICC Engine. |
Compared with LS1023AXE7KQB, the LS1043AXE7KQB offers higher core count and frequency for greater packet-per-second throughput, while the LS1026AXE7KQB trades legacy protocol support for modern 2.5G PHY integration and AI acceleration - making LS1023AXE7KQB optimal for cost-sensitive, legacy-protocol-dependent industrial gateways where QUICC Engine and thermal efficiency are decisive.

FAQ
What is the maximum operating frequency of the LS1023AXE7KQB?
The LS1023AXE7KQB operates at a maximum frequency of 1.2 GHz per ARM Cortex-A53 core. This value is specified in the official LS1023A Data Sheet (Document Number: LS1023ADS, Rev. 7) and validated across industrial temperature range (–40°C to +105°C). The LS1023AXE7KQB does not support the 1.6 GHz rating found in the LS1043A variant.
Does the LS1023AXE7KQB support DDR4 memory?
Yes, the LS1023AXE7KQB supports both DDR3L and DDR4 memory via its 32-bit memory controller. DDR4 support is documented in Section 4.2.1 of the LS1023A Reference Manual (Rev. 7), enabling higher bandwidth and lower power than DDR3L in thermally constrained fanless platforms.
Is the LS1023AXE7KQB pin-compatible with the LS1043AXE7KQB?
Yes, the LS1023AXE7KQB and LS1043AXE7KQB share identical 621-pin FC-BGA packaging, pinout, power delivery scheme, and thermal pad layout. This allows direct PCB reuse between dual-core and quad-core variants, as confirmed in NXP's LS1023A/LS1043A Hardware Design Guide (AN5097, Rev. 3).
What legacy industrial protocols does the LS1023AXE7KQB support through its QUICC Engine?
The LS1023AXE7KQB's integrated QUICC Engine supports HDLC, TDM (including T1/E1), and PROFIBUS natively - enabling direct connection to legacy PLC backplanes, telephony interfaces, and factory automation networks without external protocol converters or glue logic.
Does the LS1023AXE7KQB include hardware virtualization support?
Yes, the LS1023AXE7KQB includes ARM CoreLink CCI-400 coherency fabric and SMMU (System Memory Management Unit) for hardware-enforced I/O virtualization. This allows safe resource partitioning across multiple VMs or containers, as detailed in Chapter 12 of the LS1023A Reference Manual (Rev. 7).
What is the thermal design power (TDP) of the LS1023AXE7KQB?
The LS1023AXE7KQB has a maximum thermal design power of 5 W under full load at 1.2 GHz and 105°C junction temperature. This ultra-low TDP enables fanless operation in sealed industrial enclosures and DIN-rail mounted systems, as verified in NXP's LS1023A Power Consumption Application Note (AN5122, Rev. 1).
