Product details
Overview
LS2084AXE7V17B 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 DPAA2 hardware acceleration for packet processing, cryptography (20 Gbps), RegEx (10 Gbps), and compression (20 Gbps). It targets carrier-grade routers, telecom infrastructure, and ADAS gateway systems.
For engineers reviewing the LS2084AXE7V17B datasheet, LS2084AXE7V17B pinout, LS2084AXE7V17B application, or LS2084AXE7V17B equivalent, key selection considerations include its automotive AEC-Q100 Grade 3 qualification (105°C Tj), SerDes lane count (16 lanes @ 10.3125 GHz), PCIe 3.0 support (four controllers, one with SR-IOV), and integrated TrustZone security architecture.
Technical Context
The LS2084AXE7V17B implements a hierarchical interconnect fabric linking eight Cortex-A72 cores, DPAA2 acceleration blocks (WRIOP, QBMan, SEC 5.2, PME 2.0, DCE 1.0), and dual DDR4 controllers. Its qDMA engine enables zero-copy data movement between peripherals and memory.
It integrates two 10 Gbps-capable SerDes banks (SD1/SD2), each configurable for PCIe, SATA, USB 3.0, or Ethernet PHY interfaces, with dedicated PLLs and impedance calibration circuitry. The chip supports hardware virtualization, SMMU-based IOMMU, and TrustZone-assisted secure boot via an embedded service processor.

Equivalent & Alternatives
The following parts are listed as comparable options for similar network processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LS2044AXE7V17B | Four Cortex-A72 cores (two dual-core clusters), same DPAA2, DDR4, and SerDes capabilities but reduced core count and L2 cache. | Targeted at cost-sensitive edge routers and lower-throughput gateways where 4-core performance suffices. | Select when full 8-core capacity is unnecessary and BOM cost reduction is prioritized over peak throughput. |
| BCM88832 | Fixed-function packet processor (not general-purpose CPU); no Arm cores, no DDR4 interface, but higher raw packet-per-second throughput. | Used in carrier-class core routers where pure forwarding performance dominates over programmability. | Choose only when application requires deterministic pps scaling beyond 100 Mpps and does not need Linux application hosting or flexible acceleration. |
Compared with LS2044AXE7V17B, LS2084AXE7V17B delivers 2× CPU core density and 2× L2 cache bandwidth for complex control-plane workloads, while BCM88832 trades programmability for fixed-function forwarding efficiency-making LS2084AXE7V17B optimal for software-defined, multi-role network appliances.

FAQ
What is the maximum DDR4 data rate supported by LS2084AXE7V17B?
The LS2084AXE7V17B supports up to 2.1 GT/s on its dual 64-bit DDR4 memory controllers in standard operation. Under AEC-Q100 Grade 3 automotive qualification, the maximum DDR4 data rate is derated to 1.8 GT/s to ensure reliable operation at 105°C junction temperature. Both configurations include ECC protection and interleaving support for enhanced reliability and bandwidth efficiency.
Does LS2084AXE7V17B support PCIe 3.0 x8 configuration?
Yes, LS2084AXE7V17B supports PCIe 3.0 x8 configuration-but only on the PCIe3 controller, which is the sole controller with SR-IOV capability and full x8/x4/x2/x1 flexibility. The other three PCIe controllers (PCIe1, PCIe2, PCIe4) support only x4/x2/x1 widths and do not implement SR-IOV, limiting their use in virtualized endpoint roles.
How is the DPAA2 acceleration block utilized in LS2084AXE7V17B?
In LS2084AXE7V17B, the DPAA2 hardware acceleration block offloads packet I/O processing-including parsing, classification, queue management (QBMan), cryptography (SEC 5.2), RegEx pattern matching (PME 2.0), and compression/decompression (DCE 1.0)-from the Cortex-A72 cores. This enables wire-rate throughput (e.g., 20 Gbps crypto) while freeing CPU resources for application-layer tasks like routing protocols or AI inference.
Is LS2084AXE7V17B pin-compatible with LS2044AXE7V17B?
Yes, LS2084AXE7V17B and LS2044AXE7V17B share identical 1292-ball FC-PBGA packaging, pinout, and power delivery architecture-enabling PCB-level compatibility. However, LS2084AXE7V17B populates additional core complex and cache logic, requiring updated firmware and thermal design to accommodate higher power consumption and heat dissipation.
What security features does LS2084AXE7V17B provide for automotive applications?
LS2084AXE7V17B provides hardware-enforced security for automotive use via Arm TrustZone, a dedicated service processor for pre-boot initialization and secure boot, and fuse-based security monitor integration. Its AEC-Q100 Grade 3 qualification ensures robustness at 105°C, and the SEC 5.2 crypto engine supports AES-GCM, SHA-2, and RSA for secure OTA updates and V2X communication in ADAS gateways.
