Product details
Overview
LS2084ASE7QQB 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 datapath 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 systems requiring deterministic low-latency I/O and hardware virtualization.
For engineers reviewing the LS2084ASE7QQB datasheet, LS2084ASE7QQB pinout, LS2084ASE7QQB application, or LS2084ASE7QQB equivalent, key selection criteria include its 1292-ball FC-PBGA package, automotive AEC-Q100 Grade 3 qualification (105°C Tj), support for eight 10G/16×1–2.5G Ethernet MACs, four PCIe 3.0 controllers (one with SR-IOV), and hardware-enforced TrustZone security architecture.
Technical Context
The LS2084ASE7QQB implements a hierarchical interconnect fabric linking eight Cortex-A72 cores, DPAA2 accelerators (WRIOP, QBMan, SEC 5.2, PME 2.0, DCE 1.0), qDMA engine, and dual DDR4 controllers - enabling concurrent control-plane, data-plane, and application-layer execution without software bottlenecks. Its SerDes subsystem provides 16 lanes configurable for PCIe, SATA, USB 3.0, or SGMII/XFI interfaces at up to 10.3125 GHz.
Hardware virtualization support includes SMMU units per PCIe controller and ARMv8-A virtualization extensions, while the service processor handles pre-boot initialization and secure boot via TrustZone-compliant trust architecture. Automotive qualification mandates derated operation: max 1.8 GHz CPU frequency and 1.8 GT/s DDR4 data rate under 105°C junction temperature.

FAQ
What is the maximum DDR4 data rate supported by LS2084ASE7QQB in automotive mode?
The LS2084ASE7QQB supports up to 1.8 GT/s DDR4 data rate when operating under AEC-Q100 Grade 3 conditions (105°C junction temperature), as specified in the NXP LS2084A datasheet Rev. 4. This derated speed ensures signal integrity and timing margin under extended thermal stress, while standard operation allows 2.1 GT/s. The LS2084ASE7QQB's dual DDR4 controllers maintain ECC protection and interleaving at both rates.
Does LS2084ASE7QQB support PCIe Gen4?
No, LS2084ASE7QQB supports PCIe 3.0 only. All four PCIe controllers operate at Gen3 speeds (8 GT/s), with PCIe3 capable of x8/x4/x2/x1 configurations and SR-IOV, while PCIe1/2/4 support x4/x2/x1 only. The SerDes lanes underlying PCIe are rated up to 10.3125 GHz, but PCIe protocol logic is Gen3-limited. LS2084ASE7QQB does not implement PCIe Gen4 link training or encoding.
How many Ethernet MACs does LS2084ASE7QQB integrate, and what speeds are supported?
The LS2084ASE7QQB integrates up to eight 10 Gbps Ethernet MACs and sixteen 1/2.5 Gbps Ethernet MACs, all accessible via its SerDes lanes configured for SGMII, XFI, or USXGMII. These MACs interface directly with the DPAA2 WRIOP for hardware-accelerated packet parsing, classification, and distribution - enabling line-rate forwarding without CPU load. LS2084ASE7QQB does not include PHYs; external PHYs or optical modules are required.
Is LS2084ASE7QQB pin-compatible with LS2044ASE7QQB?
Yes, LS2084ASE7QQB and LS2044ASE7QQB share identical 1292-ball FC-PBGA packaging, pinout, and mechanical footprint, enabling PCB reuse across both SKUs. Functional differences (core count, cache size, platform cache) are implemented internally; all I/O signals, power domains, and thermal pads align. This allows scalable design migration from four-core to eight-core deployment without layout changes.
What security features does LS2084ASE7QQB provide beyond TrustZone?
LS2084ASE7QQB extends TrustZone with a dedicated service processor (SP) that enforces secure boot, manages cryptographic keys in tamper-resistant memory, and monitors runtime integrity. It also integrates hardware security engine (SEC 5.2) for AES-GCM, SHA-2, RSA/ECC acceleration, and supports secure debug disable, fuse-based provisioning, and battery-backed security monitor interfaces - all documented in the LS2084A security chapter. LS2084ASE7QQB does not rely on external TPMs for these functions.
