Product details
Overview
LS2044AXE711B from NXP Semiconductors is a quad-core Arm® Cortex®-A72 SoC with two 1 MB L2 cache clusters, 2.1 GHz max CPU frequency, dual 64-bit DDR4 memory controllers (2.1 GT/s, ECC), and DPAA2 hardware acceleration for networking workloads. It serves as a control-and-data-path processor in vehicle gateways and ADAS domain controllers.
For engineers reviewing the LS2044AXE711B datasheet, LS2044AXE711B pinout, LS2044AXE711B application, or LS2044AXE711B equivalent, key selection criteria include DDR4 ECC support, SerDes lane count (16 lanes up to 10.3125 GHz), PCIe 3.0 configurability (four controllers, one with SR-IOV), and automotive AEC-Q100 Grade 3 qualification at 105°C junction temperature.
Technical Context
The LS2044AXE711B implements a hierarchical interconnect fabric linking four Cortex-A72 cores (two dual-core clusters), 1 MB platform cache with ECC, and DPAA2 accelerators including WRIOP, QBMan, SEC 5.2 (20 Gbps crypto), PME 2.0 (10 Gbps RegEx), and DCE 1.0 (20 Gbps compression/decompression). Its qDMA engine enables zero-copy data movement across peripherals.
It integrates two DDR4 SDRAM controllers supporting interleaving and ECC, eight 10 Gbps Ethernet MACs, sixteen 1/2.5 Gbps Ethernet MACs, four PCIe 3.0 controllers (PCIe3 supports x8/x4/x2/x1 + SR-IOV; others support x4/x2/x1 only), two SATA 3.0, two USB 3.0 with PHY, and TrustZone®-enabled secure boot via service processor.

FAQ
What is the maximum operating frequency of the LS2044AXE711B?
The LS2044AXE711B operates at up to 2.1 GHz under standard conditions. In automotive AEC-Q100 Grade 3 mode (105°C Tj), its maximum CPU frequency is reduced to 1.8 GHz to maintain thermal and reliability margins. This derated speed is fully supported in the LS2044AXE711B's power management firmware and validated across temperature and voltage corners.
Does the LS2044AXE711B support DDR4 ECC and memory interleaving?
Yes, the LS2044AXE711B integrates two independent 64-bit DDR4 memory controllers, each supporting ECC protection and address/data interleaving. This configuration enables error detection and correction on all memory transactions and improves effective bandwidth by distributing accesses across both channels - critical for ASIL-B/C safety domains in the LS2044AXE711B.
How many PCIe 3.0 controllers does the LS2044AXE711B include, and which support SR-IOV?
The LS2044AXE711B includes four PCIe 3.0 controllers: PCIe3 supports x8/x4/x2/x1 widths and SR-IOV, while PCIe1, PCIe2, and PCIe4 support only x4/x2/x1 and lack SR-IOV capability. This architecture allows the LS2044AXE711B to host virtualized endpoints on PCIe3 while dedicating other controllers to fixed-function peripherals like NVMe storage or FPGA co-processors.
Is the LS2044AXE711B qualified for automotive applications?
Yes, the LS2044AXE711B is AEC-Q100 Grade 3 qualified for operation at 105°C junction temperature. It includes automotive-specific features such as enhanced ESD robustness, extended temperature characterization, and failure-in-time (FIT) data compliant with ISO 26262. These qualifications are documented in the official NXP LS2044A automotive datasheet revision.
What hardware acceleration blocks are included in the LS2044AXE711B's DPAA2 architecture?
The LS2044AXE711B's DPAA2 includes WRIOP for packet parsing/classification, QBMan for hardware queue and buffer management, SEC 5.2 for cryptography (20 Gbps), PME 2.0 for RegEx pattern matching (10 Gbps), and DCE 1.0 for compression/decompression (20 Gbps). All blocks are integrated into the coherent interconnect and accessible directly by Cortex-A72 cores without software driver overhead.
