Product details
Overview
LS2084ACE7TTB from NXP Semiconductors is an 8-core Arm® Cortex®-A72 SoC with DPAA2 data path acceleration, dual 64-bit DDR4 memory controllers (up to 2.1 GT/s), 16 SerDes lanes (up to 10.3125 GHz), and integrated security engine (SEC 5.2) delivering up to 20 Gbps crypto throughput. It serves as a control-and-data-plane processor in high-throughput network infrastructure and automotive ADAS gateways.
For engineers reviewing the LS2084ACE7TTB datasheet, LS2084ACE7TTB pinout, LS2084ACE7TTB application, or LS2084ACE7TTB equivalent, key selection considerations include its AEC-Q100 Grade 3 qualification (105°C Tj), hardware virtualization support, TrustZone®-enabled secure boot via service processor, and PCIe 3.0 SR-IOV capability on one controller.
Technical Context
The LS2084ACE7TTB implements eight Cortex-A72 cores organized in four clusters (2 cores/cluster, 1 MB shared L2 cache per cluster), backed by a 1 MB platform cache with ECC. Its hierarchical interconnect fabric links CPU clusters, accelerators, and I/O subsystems coherently.
DPAA2 integrates WRIOP for packet parsing/classification, QBMan for hardware queue/buffer management, SEC 5.2 for crypto, PME 2.0 for RegEx matching (10 Gbps), and DCE 1.0 for compression/decompression (20 Gbps), all operating at wire rate across up to eight 10 Gbps Ethernet MACs.

FAQ
What is the maximum DDR4 data rate supported by the LS2084ACE7TTB?
The LS2084ACE7TTB supports up to 2.1 GT/s DDR4 data rate in standard operation. Under AEC-Q100 Grade 3 qualification (105°C Tj), the maximum DDR4 data rate is derated to 1.8 GT/s to ensure signal integrity and thermal stability across automotive temperature ranges. This is explicitly defined in Section 3.8 of the LS2084A Data Sheet Rev. 4.
Does the LS2084ACE7TTB include hardware support for virtualization?
Yes, the LS2084ACE7TTB implements full ARMv8 virtualization extensions including stage-2 translation, nested page tables, and hypervisor mode. It supports hardware-enforced partitioning of CPU resources, memory, and peripherals-critical for running mixed-criticality workloads such as AUTOSAR Adaptive alongside Linux RT in ADAS systems. This capability is documented in the "Hardware Virtualization and Partitioning Enforcement" feature section.
Which PCIe controller on the LS2084ACE7TTB supports SR-IOV?
Only PCIe3 (the third PCIe controller) on the LS2084ACE7TTB supports Single Root I/O Virtualization (SR-IOV). The other three controllers (PCIe1, PCIe2, PCIe4) support only x4/x2/x1 widths and lack SR-IOV functionality. This distinction is specified in the "High-speed peripheral interfaces" section of the LS2084A Data Sheet, Rev. 4.
Is the LS2084ACE7TTB qualified for automotive applications?
Yes, the LS2084ACE7TTB is AEC-Q100 Grade 3 qualified for operation up to 105°C junction temperature. This qualification includes validated derating of CPU frequency to 1.8 GHz and DDR4 data rate to 1.8 GT/s under high-temperature conditions. The qualification status and test conditions are detailed in the "Automotive AEC-Q100 Grade 3 qualified" subsection of the features list.
How does the DPAA2 architecture accelerate packet processing in the LS2084ACE7TTB?
The DPAA2 architecture in the LS2084ACE7TTB accelerates packet processing through dedicated hardware blocks: WRIOP performs wire-rate parsing, classification, and distribution; QBMan handles scheduling, sequencing, and buffer management; SEC 5.2 delivers up to 20 Gbps crypto; and PME 2.0 achieves 10 Gbps RegEx matching. These operate independently of CPU cores, reducing software overhead and jitter-key for 5G fronthaul and industrial TSN applications.
