Product details
Overview
LS2084ASE7V17B 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 (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 LS2084ASE7V17B datasheet, LS2084ASE7V17B pinout, LS2084ASE7V17B application, or LS2084ASE7V17B equivalent, key selection considerations include its 1292-ball FC-PBGA package, automotive AEC-Q100 Grade 3 qualification (105°C Tj), SR-IOV-capable PCIe 3.0 x8 controller, and integrated TrustZone security architecture with service processor boot enforcement.
Technical Context
The LS2084ASE7V17B implements a hierarchical interconnect fabric linking eight Cortex-A72 cores, DPAA2 acceleration complex (WRIOP, QBMan, SEC 5.2, PME 2.0, DCE 1.0), qDMA engine, and dual DDR4 controllers. Its SerDes subsystem provides 16 lanes configurable up to 10.3125 GHz for Ethernet, PCIe, and SATA interfaces.
Hardware virtualization support includes SMMU units per PCIe root complex and ARMv8-A virtualization extensions. The service processor handles pre-boot initialization, secure boot, and trust architecture enforcement via TrustZone, while the platform supports ECC on L2 cache, DDR4, and platform cache.

FAQ
What is the maximum DDR4 data rate supported by LS2084ASE7V17B?
The LS2084ASE7V17B supports up to 2.1 GT/s on both DDR4 memory controllers under standard industrial conditions. In AEC-Q100 Grade 3 automotive qualification mode, the maximum DDR4 data rate is reduced to 1.8 GT/s to ensure reliable operation at 105°C junction temperature. This derating is enforced by hardware configuration fuses and validated in the LS2084ASE7V17B datasheet Section 3.8.
Does LS2084ASE7V17B support PCIe Gen3 x8 with SR-IOV?
Yes, LS2084ASE7V17B's PCIe3 controller fully supports PCIe Gen3 x8 operation with Single Root I/O Virtualization (SR-IOV). This capability is confirmed in the LS2084A datasheet Section 1 Features and Table 3-12 (Electrical Characteristics). The other three PCIe controllers (PCIe1, PCIe2, PCIe4) support only Gen1/Gen2 and lack SR-IOV functionality.
How does the service processor (SP) in LS2084ASE7V17B enhance security?
The service processor in LS2084ASE7V17B performs pre-boot initialization, executes secure boot ROM code, validates cryptographic signatures of boot images, and enforces TrustZone-based isolation between secure and non-secure worlds. It manages hardware security fuses and provides tamper-evident monitoring-functions detailed in LS2084A datasheet Sections 1 Overview and 7 Security Fuse Processor.
What SerDes protocols can be configured on LS2084ASE7V17B's 16 lanes?
LS2084ASE7V17B's 16 SerDes lanes support PCIe (Gen1/2/3), SATA 3.0 (6 Gbps), SGMII/QSGMII, XAUI, and CPRI/eCPRI protocols. Configuration is done via RCW (Reset Configuration Word) settings during boot; lane mapping and protocol assignment are documented in LS2084A datasheet Section 4.1 and the QorIQ LS2084A Hardware Specification.
Is LS2084ASE7V17B pin-compatible with LS2044ASE7V17B?
Yes, LS2084ASE7V17B and LS2044ASE7V17B share identical 1292-ball FC-PBGA packaging, pinout, and mechanical footprint. This allows PCB reuse between the two variants, differing only in internal core count and power delivery tuning-details confirmed in NXP's LS2084A/LS2044A Data Sheet Rev. 4, Section 6 Package Information.
