Product details
Overview
LS2084AXE711B from NXP Semiconductors is a high-performance 64-bit Arm Cortex-A72-based network processor with eight A72 cores (four dual-core clusters), 1 MB platform cache with ECC, dual 64-bit DDR4 memory controllers supporting up to 2.1 GT/s, and integrated DPAA2 acceleration for wire-rate packet processing, cryptography (20 Gbps), RegEx (10 Gbps), and compression (20 Gbps). It targets carrier-grade routers, telecom infrastructure, and ADAS gateway servers.
For engineers reviewing the LS2084AXE711B datasheet, LS2084AXE711B pinout, LS2084AXE711B application, or LS2084AXE711B equivalent, key selection criteria include DDR4 ECC support, SerDes lane count (16 lanes @ 10.3125 GHz), PCIe 3.0 configuration flexibility (including SR-IOV on PCIe3), automotive AEC-Q100 Grade 3 qualification, and DPAA2 hardware offload capabilities for L2–L4 networking workloads.
Technical Context
The LS2084AXE711B implements a hierarchical interconnect fabric linking eight Cortex-A72 cores, dual DDR4 controllers, DPAA2 acceleration complex (WRIOP, QBMan, SEC 5.2, PME 2.0, DCE 1.0), and multiple high-speed I/O subsystems. Its cache coherency architecture supports cluster-level 1 MB L2 caches (two per cluster) plus a unified 1 MB platform cache with ECC protection.
It integrates 16 SerDes lanes configurable for PCIe 3.0, SATA 3.0, USB 3.0, and Ethernet PHY interfaces; four PCIe 3.0 controllers (one with SR-IOV); eight 10 GbE MACs; and hardware virtualization support with TrustZone-enforced security partitioning. The service processor enables secure boot and pre-boot initialization.

Equivalent & Alternatives
The following parts are listed as comparable options for similar network processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LS2044AXE711B | Four Cortex-A72 cores (two dual-core clusters), same DPAA2, DDR4, and I/O features but halved core count and platform cache bandwidth | Targeted at mid-range edge routers and compact ADAS gateways where 4-core compute and lower thermal envelope are sufficient | Select when full 8-core capacity is unnecessary and BOM cost reduction is prioritized over peak throughput scalability |
| LS1046AXE711B | Quad-core Cortex-A72 with DPAA2 Lite (no PME/RegEx, reduced SEC throughput), single DDR4 controller, no AEC-Q100 qualification | Suitable for cost-sensitive industrial gateways and SD-WAN CPE requiring basic crypto and packet acceleration without automotive or 10G+ Ethernet demands | Choose for non-automotive applications needing proven software compatibility and lower power (12W TDP vs. LS2084A's 22W) |
Compared with LS2044AXE711B and LS1046AXE711B, the LS2084AXE711B delivers higher deterministic throughput for multi-tenant 5G fronthaul and automotive domain control due to its 8-core cluster topology, full DPAA2 feature set, and AEC-Q100 qualification - making it the only option among the three qualified for safety-critical vehicle gateway deployment.

FAQ
What is the maximum DDR4 data rate supported by the LS2084AXE711B?
The LS2084AXE711B supports up to 2.1 GT/s DDR4 data rate in standard operation. Under AEC-Q100 Grade 3 conditions (105°C junction temperature), the maximum DDR4 data rate is derated to 1.8 GT/s to ensure signal integrity and reliability in automotive environments. This specification is validated per JEDEC JESD79-4 and documented in Section 3.8 of the LS2084A Data Sheet Rev. 4.
Does the LS2084AXE711B support PCIe Gen4?
No, the LS2084AXE711B supports PCIe 3.0 only. All four PCIe controllers operate at Gen3 speeds with configurable widths (x8/x4/x2/x1 for PCIe3; x4/x2/x1 for PCIe1/2/4). Gen4 capability is not implemented in the SerDes PHY or link layer logic of the LS2084AXE711B, and no firmware or configuration enables Gen4 signaling.
How many SerDes lanes does the LS2084AXE711B provide, and what protocols do they support?
The LS2084AXE711B provides 16 SerDes lanes operating up to 10.3125 GHz. These lanes are protocol-agnostic and can be configured for PCIe 3.0, SATA 3.0, USB 3.0, IEEE 1588-compliant Ethernet PHYs, or custom high-speed serial interfaces via the HSSI framework. Configuration is performed at boot via RCW (Reset Configuration Word) settings.
Is the LS2084AXE711B pin-compatible with other QorIQ LS20xx devices?
No, the LS2084AXE711B is not pin-compatible with LS2044A or LS1046A. Although all use 1292-ball FC-PBGA packages, ball mapping differs significantly - especially for DDR4, SerDes, and peripheral interfaces. Pinout validation confirms unique assignments for D1/D2 memory channels, SD1/SD2 SerDes banks, and PCIe reference clocks, requiring dedicated PCB layout.
What security features are implemented in hardware on the LS2084AXE711B?
The LS2084AXE711B implements TrustZone-based hardware isolation, secure boot enforced by the service processor (SP), cryptographic acceleration via SEC 5.2 (AES-GCM, SHA-2, RSA/ECC), tamper-resistant security fuses, and battery-backed security monitor interface. These features are silicon-proven and documented in Sections 7 and 3.21 of the LS2084A Data Sheet Rev. 4.
