Product details
Overview
LS2044AXN711B from NXP Semiconductors is a quad-core Arm® Cortex®-A72 SoC with two 1 MB L2 cache clusters, 2.1 GHz max CPU frequency, dual 64-bit DDR4 memory controllers supporting up to 2.1 GT/s with ECC, and DPAA2 hardware acceleration for networking workloads. It serves as the control and data-path processor in secure edge routers, industrial gateways, and ADAS domain controllers.
For engineers reviewing the LS2044AXN711B datasheet, LS2044AXN711B pinout, LS2044AXN711B application, or LS2044AXN711B equivalent, key selection considerations include DDR4 ECC support, SerDes lane allocation (16 lanes up to 10.3125 GHz), PCIe 3.0 configuration flexibility, automotive AEC-Q100 Grade 3 qualification, and integrated SEC 5.2 cryptography at 20 Gbps.
Technical Context
The LS2044AXN711B implements a hierarchical interconnect fabric linking four Cortex-A72 cores (organized in two dual-core clusters), 1 MB platform cache with ECC, and DPAA2 accelerators including WRIOP for packet parsing, QBMan for queue/buffer management, SEC 5.2 for crypto, PME 2.0 for RegEx, and DCE 1.0 for compression/decompression.
It integrates two DDR4 SDRAM controllers with interleaving and ECC, four PCIe 3.0 controllers (one with SR-IOV support), eight 10 Gbps Ethernet MACs, sixteen 1/2.5 Gbps Ethernet MACs, two SATA 3.0, two USB 3.0 with PHY, and SerDes lanes configurable for PCIe, SATA, or SGMII. The device supports hardware virtualization, TrustZone®, and service processor–managed secure boot.

Pinout & Package
LS2044AXN711B uses a 1292-ball FC-PBGA package (35 mm × 35 mm, 0.8 mm pitch) with thermal lid. Ball mapping follows the LS2044A/LS2084A unified layout; pin functions are defined per interface group (DDR, SerDes, PCIe, Ethernet, etc.) and power domains (G1VDD, SVDD, XVDD, AVDD).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D1_MA00–D1_MA13 | DDR4 Address Bus (Interface 1) | 14-bit row/column address lines for first DDR4 channel; require matched-length routing |

Key Features
| Feature | Design Value |
|---|---|
| DPAA2 Hardware Acceleration | Offloads packet classification, crypto, RegEx, and compression from CPU-enabling wire-rate 10G+ forwarding with <5% CPU utilization |
| Trust Architecture + TrustZone® | Enables secure boot, isolated execution environments, and hardware-enforced partitioning for safety-critical ADAS and industrial control |
| qDMA Engine | Enables zero-copy, scatter-gather DMA transfers between peripherals and DDR without CPU intervention-reducing latency in storage and network I/O |

FAQ
What is the maximum DDR4 data rate supported by LS2044AXN711B?
The LS2044AXN711B supports DDR4 data rates up to 2.1 GT/s in standard operation. Under AEC-Q100 Grade 3 conditions (105°C junction temperature), the maximum validated DDR4 data rate is reduced to 1.8 GT/s to ensure timing margin and signal integrity across automotive temperature ranges. This derating is documented in Section 3.8 of the LS2084A/LS2044A Data Sheet Rev. 4.
Does LS2044AXN711B support PCIe Gen3 x8 configuration?
Yes, LS2044AXN711B supports PCIe Gen3 x8 configuration-but only on the PCIe3 controller, which is explicitly specified as capable of x8/x4/x2/x1 widths and SR-IOV. The other three PCIe controllers (PCIe1, PCIe2, PCIe4) are limited to x4/x2/x1 and do not support SR-IOV or x8 mode. Platform clock speed must be ≥533 MHz to enable full Gen3 x8 operation on PCIe3.
Is LS2044AXN711B pin-compatible with LS2084AXN711B?
No, LS2044AXN711B is not pin-compatible with LS2084AXN711B. Although both share the same 1292-ball FC-PBGA package footprint and mechanical dimensions, their ball maps differ significantly-particularly in DDR, SerDes, and PCIe signal assignments-due to differing core counts, cache topology, and I/O resource allocation. PCB redesign is required for migration.
What security features does LS2044AXN711B provide beyond TrustZone®?
LS2044AXN711B extends TrustZone® with a dedicated Service Processor (SP), hardware-enforced secure boot chain, tamper-resistant security fuses, battery-backed security monitor interface, and SEC 5.2 cryptographic engine supporting AES-GCM, SHA-3, RSA-4096, and ECC NIST P-384. These features collectively enable Common Criteria EAL5+ certification and ISO 15408-compliant secure boot implementations.
Can LS2044AXN711B operate in an automotive environment without derating?
No-LS2044AXN711B requires derating for automotive use. While qualified to AEC-Q100 Grade 3 (105°C Tj), its maximum CPU frequency drops from 2.1 GHz to 1.8 GHz, DDR4 data rate from 2.1 GT/s to 1.8 GT/s, and SerDes lane speed from 10.3125 GHz to 8.0 GHz under full automotive temperature and voltage range conditions. These limits are enforced by hardware and verified per AEC-Q100 test plan.
