Overview
LS2084ASE711B from NXP Semiconductors is a high-performance 64-bit Arm® Cortex®-A72-based network processor with eight A72 cores (four dual-core clusters), 2.1 GHz max CPU frequency, dual 64-bit DDR4 memory controllers supporting up to 2.1 GT/s with ECC, and integrated DPAA2 datapath acceleration for wire-rate packet processing in telecom and networking infrastructure.
For engineers reviewing the LS2084ASE711B datasheet, LS2084ASE711B pinout, LS2084ASE711B application, or LS2084ASE711B equivalent, key selection considerations include its automotive-grade AEC-Q100 Grade 3 qualification (105°C Tj), SerDes lane configuration (16 lanes up to 10.3125 GHz), PCIe 3.0 support (including SR-IOV on one controller), and hardware virtualization enforcement for secure embedded control-plane and data-path consolidation.
Technical Context
The LS2084ASE711B implements a hierarchical interconnect fabric linking eight Cortex-A72 cores, 1 MB platform cache with ECC, and DPAA2 accelerators including WRIOP for packet parsing/classification, QBMan for queue/buffer management, SEC 5.2 crypto engine (20 Gbps), PME 2.0 RegEx (10 Gbps), and DCE 1.0 compression/decompression (20 Gbps). It integrates qDMA for low-latency memory transfers across subsystems.
Its I/O subsystem includes two DDR4 controllers (up to 2.1 GT/s), four PCIe 3.0 controllers (one with SR-IOV), eight 10G/16×1–2.5G Ethernet MACs, two SATA 3.0, two USB 3.0 PHYs, dual SDHC, QuadSPI, SPI, four I²C, two DUARTs, and integrated flash controller - all coordinated via a security-enforced TrustZone®-enabled service processor for pre-boot initialization and secure boot.

Equivalent & Alternatives
The following parts are listed as comparable options for similar network processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LS2044ASE711B | Four Cortex-A72 cores (two dual-core clusters), same DPAA2, DDR4, SerDes, and peripheral set; lower core count and power envelope. | Targeted at cost-sensitive 1–2 Gbps edge routers and entry-level gateways where full 8-core capacity is unnecessary. | Select when application workload fits within 4 cores and thermal/power budget is constrained; shares identical pinout and software compatibility. |
| BCM88832 | Broadcom Trident4 switch ASIC with integrated 128x25G SerDes, no general-purpose CPU cores; fixed-function L2/L3 forwarding engine. | Designed for high-port-count data center switches; lacks programmable control plane, OS support, or application-layer processing capability. | Choose only for pure switching applications requiring >100 Gbps non-blocking fabric; not suitable for control-plane hosting or custom protocol stacks. |
Compared with LS2084ASE711B, LS2044ASE711B offers identical architecture and software ecosystem at reduced core count and power, while BCM88832 delivers higher switching density but eliminates programmable CPU functionality - making LS2084ASE711B optimal for hybrid control/data-path workloads requiring both flexibility and acceleration.

FAQ
What is the maximum DDR4 data rate supported by LS2084ASE711B?
The LS2084ASE711B supports up to 2.1 GT/s DDR4 data rate in standard industrial operation. Under AEC-Q100 Grade 3 automotive qualification, the maximum DDR4 data rate is derated to 1.8 GT/s to ensure reliability at 105°C junction temperature. Both configurations maintain full ECC protection and interleaving support across dual 64-bit channels.
Does LS2084ASE711B support PCIe Gen4?
No, LS2084ASE711B supports PCIe 3.0 only. It features four PCIe 3.0 controllers: PCIe3 supports x8/x4/x2/x1 widths and SR-IOV, while PCIe1/2/4 support x4/x2/x1 widths without SR-IOV. At platform clock speeds below 533 MHz, PCIe3 is limited to x4 width at Gen3, and other controllers to x2 width - no Gen4 signaling capability is implemented.
How many Ethernet MACs does LS2084ASE711B integrate?
The LS2084ASE711B integrates up to eight 10 Gbps Ethernet MACs and sixteen 1/2.5 Gbps Ethernet MACs, all accessible via the internal SerDes lanes. These MACs support IEEE 1588 precision time protocol with hardware timestamping, enabling sub-100 ns synchronization accuracy required for TSN and industrial automation applications.
Is LS2084ASE711B pin-compatible with LS2044ASE711B?
Yes, LS2084ASE711B and LS2044ASE711B share identical 1292-ball FC-PBGA package, pinout, and power delivery requirements. This allows direct PCB reuse between the 8-core and 4-core variants, simplifying platform scaling and reducing layout validation effort for customers targeting multiple performance tiers.
What security features are implemented in LS2084ASE711B beyond TrustZone®?
LS2084ASE711B implements a comprehensive hardware security stack beyond Arm TrustZone®, including a dedicated service processor for pre-boot initialization and secure boot, cryptographic acceleration (SEC 5.2) supporting AES-GCM, SHA-256, ECDSA, and RSA-2048, tamper-detect circuitry, battery-backed security monitor, and fuse-based key storage - meeting Common Criteria EAL4+ and FIPS 140-2 Level 3 requirements.
