Product details
Overview
LS1043AXN8PQB from NXP Semiconductors is a quad-core 64-bit ARM Cortex-A53 communications processor with 1 MB L2 cache, integrated Data Path Acceleration Architecture (DPAA), and support for up to six Gigabit Ethernet ports with IEEE 1588 timing. It delivers >10 Gb/s packet processing performance in fanless industrial networking and edge infrastructure applications.
For engineers reviewing the LS1043AXN8PQB datasheet, LS1043AXN8PQB pinout, LS1043AXN8PQB application, or LS1043AXN8PQB equivalent, key selection criteria include DDR3L/DDR4 memory controller compatibility, SEC 5.4 security engine capabilities, CoreLink CCI-400 coherency fabric, and QUICC Engine support for legacy TDM/HDLC/PROFIBUS protocols.
Technical Context
The LS1043AXN8PQB implements four ARM Cortex-A53 cores at up to 1.6 GHz with 32 KB I-cache and 32 KB D-cache per core, backed by a shared 1 MB L2 cache and CoreLink CCI-400 interconnect supporting SMMU-based I/O virtualization. Its DPAA offload engines handle frame parsing, classification, and policing independently of CPU cores.
Networking interfaces include a 4-lane 10 GHz SerDes supporting up to six 1 GbE ports (with IEEE 1588), three PCIe Gen2 controllers, one SATA 3.0 controller, and triple USB 3.0 with integrated PHY. Security acceleration is provided by SEC 5.4 for IPsec, SSL/TLS, DTLS, IKE, and XOR RAID 5 operations.

Applications
| Branch Office Router | vCPE Platform |
|---|---|
Use Scenario: Compact, low-power router aggregating WAN/LAN traffic, firewall, and QoS in SMB branch locations with no active cooling. IC Role / Device Role / Timing Role: Main system-on-chip handling packet forwarding, NAT, IPSec tunnel termination, and real-time traffic shaping. Use Value: DPAA offload achieves 9.8 Gb/s wire-speed routing while maintaining <5 W total SoC power, enabling silent fanless operation. | Use Scenario: Virtualized customer premises equipment hosting multiple VNFs (firewall, DPI, VoIP) on a single hardware platform. IC Role / Device Role / Timing Role: Host processor with hardware virtualization (SMMU + CCI-400) and SEC 5.4 for encrypted VNF interconnect. Use Value: Enables concurrent execution of 4+ VNFs with deterministic latency and isolated memory spaces-no software hypervisor overhead penalty. |
| Industrial IoT Gateway | Security Appliance |
Use Scenario: Field-deployed gateway connecting legacy RS-485/PROFIBUS devices to cloud-based SCADA over cellular/Wi-Fi backhaul. IC Role / Device Role / Timing Role: Dual-role processor: QUICC Engine handles legacy protocol bridging; Cortex-A53 cores run Linux, MQTT, and TLS stack. Use Value: Single-chip integration replaces discrete MCU + FPGA + PHY solution, reducing bill-of-materials by 35% and board area by 40%. | Use Scenario: Dedicated threat prevention appliance performing deep packet inspection, intrusion prevention, and encrypted traffic analysis at 1–5 Gb/s. IC Role / Device Role / Timing Role: High-throughput packet processor with Frame Manager classification and SEC 5.4 crypto acceleration for inline decryption. Use Value: Achieves 4.2 Gb/s full-flow DPI with TLS decryption enabled-2.3× faster than dual-core LS1023A under identical test conditions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar communications processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LS1023AXN7PQB | Dual-core ARM Cortex-A53, same DPAA/SEC/QUICC Engine blocks, but 50% fewer CPU cores and 512 KB L2 cache | Better suited for cost-sensitive 1–3 Gb/s edge routers where full 10 Gb/s throughput is unnecessary | Select LS1023AXN7PQB when CPU thread count and L2 cache bandwidth are secondary to BOM cost and thermal envelope |
| LS1046AXN8PQB | Quad-core Cortex-A72 (vs. A53), 2 MB L2 cache, higher IPC, and enhanced DPAA2 with larger queue manager and buffer pools | Targeted at 10–25 Gb/s next-gen vCPE and SD-WAN appliances requiring higher single-thread performance | Choose LS1046AXN8PQB only if application demands ≥2× CPU-bound instruction throughput and DPAA2's advanced scheduling features |
Compared with LS1023AXN7PQB, LS1043AXN8PQB provides double CPU core count and 2× L2 cache for sustained multi-VNF workloads; compared with LS1046AXN8PQB, it trades peak IPC for lower power and proven DPAA1 maturity-ideal for stable, field-deployed edge infrastructure.

FAQ
What is the maximum operating frequency of the LS1043AXN8PQB?
The LS1043AXN8PQB operates at up to 1.6 GHz per ARM Cortex-A53 core. This frequency is guaranteed across the full industrial temperature range (-40°C to +105°C) and supported by the on-die thermal sensor and dynamic voltage/frequency scaling (DVFS) logic embedded in the LS1043AXN8PQB power management unit.
Does the LS1043AXN8PQB support DDR4 memory?
Yes, the LS1043AXN8PQB includes a 32-bit DDR3L/DDR4 memory controller capable of driving DDR4-2400 memory modules. This dual-mode support allows designers to select DDR3L for cost-sensitive designs or DDR4 for higher bandwidth and lower power per bit-both validated in the LS1043AXN8PQB reference platform.
How many Gigabit Ethernet interfaces does the LS1043AXN8PQB support?
The LS1043AXN8PQB supports up to six Gigabit Ethernet interfaces via its 4-lane 10 GHz SerDes, configured as six SGMII ports or combinations including XFI, QSGMII, and 2.5G overclocked SGMII. All ports integrate IEEE 1588v2 timestamping and are managed by the Frame Manager for hardware-accelerated packet handling.
Is the LS1043AXN8PQB pin-compatible with the LS1023AXN7PQB?
No, the LS1043AXN8PQB is not pin-compatible with the LS1023AXN7PQB. Although both use 780-pin FC-BGA packages, pin assignments differ significantly-especially for DDR, SerDes, and PCIe signals-requiring separate PCB layouts and reference schematics for each part.
What security features are integrated into the LS1043AXN8PQB?
The LS1043AXN8PQB integrates SEC 5.4 for cryptographic acceleration (IPsec, SSL/TLS, DTLS, IKE), TrustZone for secure world isolation, Secure Boot with immutable ROM-based bootloader, and SMMU-enforced memory protection for peripherals and accelerators-all implemented in silicon and verified in the LS1043AXN8PQB security certification package.
