Product details
Overview
LS2044ASN711B from NXP Semiconductors is a quad-core Arm® Cortex®-A72 SoC with two 64-bit DDR4 memory controllers (up to 2.1 GT/s), DPAA2 hardware acceleration (20 Gbps crypto, 10 Gbps RegEx), and 16 SerDes lanes (up to 10.3125 GHz), deployed in vehicle management servers and ADAS gateways.
For engineers reviewing the LS2044ASN711B datasheet, LS2044ASN711B pinout, LS2044ASN711B application, or LS2044ASN711B equivalent, key selection criteria include DDR4 ECC support, PCIe 3.0 x8/x4 capability, automotive AEC-Q100 Grade 3 qualification (105°C Tj), and integrated TrustZone®-enabled secure boot via service processor.
Technical Context
The LS2044ASN711B implements a hierarchical interconnect fabric linking four Cortex-A72 cores (two dual-core clusters, 1 MB L2 cache per cluster), 1 MB platform cache with ECC, and DPAA2 subsystem including WRIOP for wire-rate packet parsing, QBMan for queue/buffer management, SEC 5.2 crypto engine, PME 2.0 RegEx accelerator, and DCE 1.0 compression/decompression.
It integrates dual 64-bit DDR4 controllers with interleaving and ECC, four PCIe 3.0 controllers (one supporting SR-IOV at x8/x4/x2/x1; three at x4/x2/x1 without SR-IOV), eight 10G/16×1–2.5G Ethernet MACs, two SATA 3.0, two USB 3.0 PHYs, and QSPI/SPI/I²C/UART peripherals - all under hardware virtualization and TrustZone®-enforced partitioning.

Pinout & Package
LS2044ASN711B uses a 1292-ball FC-PBGA package (35 mm × 35 mm, 0.8 mm pitch) with thermal lid and standard JEDEC MO-271AC mechanical outline. Ball map includes dedicated DDR4, SerDes, PCIe, Ethernet, and peripheral interface banks with power/ground distribution optimized for signal integrity and thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D1_MA00–D1_MA13 | DDR4 Address Bus (Interface 1) | 14-bit address lines driving first DDR4 channel; require matched-length routing and termination for stable 2.1 GT/s operation. |
| D1_MCK0/D1_MCK0_B | DDR4 Clock (Interface 1) | Differential clock pair for DDR4 channel 1; routed as controlled-impedance differential pair with tight skew control. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar multicore Arm-based networking and embedded computing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LS2084ASN711B | Eight Cortex-A72 cores (four dual-core clusters), higher core count and DDR bandwidth vs. LS2044A. | Better suited for control-plane + data-plane separation in high-port-count switches or hypervisor-hosted multi-VM deployments. | Select when >4 cores or >2× DDR4 bandwidth is required; same package and pinout enable drop-in upgrade path. |
| LS1046ASN7QQB | Quad Cortex-A72 cores but no DPAA2 acceleration; uses legacy DPAA 1.0 with lower crypto/RegEx performance. | Limited to <5 Gbps crypto or RegEx workloads; lacks SEC 5.2, PME 2.0, and DCE 1.0 blocks present in LS2044A. | Choose for cost-sensitive designs where DPAA2 acceleration is unnecessary and AEC-Q100 Grade 3 is not required. |
Compared with LS2084ASN711B, the LS2044ASN711B delivers identical architecture and pin compatibility at lower power and cost for 4-core workloads; versus LS1046ASN7QQB, it adds DPAA2 acceleration, AEC-Q100 Grade 3, and enhanced PCIe/SerDes capabilities - making it the optimal choice for automotive and high-performance secure networking.

FAQ
What is the thermal design power (TDP) of the LS2044ASN711B?
The LS2044ASN711B does not specify a single TDP value in its public documentation; instead, power consumption is characterized across operating modes (idle, typical, max) and voltage/frequency points. At 2.1 GHz with full DDR4 and SerDes activity, peak power draw exceeds 15 W - requiring active cooling and careful PCB thermal layout per NXP's AN5422 guidelines. The LS2044ASN711B datasheet provides detailed DC electrical characteristics and power sequencing tables for accurate system-level estimation.
Does the LS2044ASN711B support PCIe Gen4?
No, the LS2044ASN711B supports PCIe 3.0 only across all four controllers. PCIe3 supports x8/x4/x2/x1 widths and SR-IOV; PCIe1/2/4 support x4/x2/x1 widths without SR-IOV. No PCIe Gen4 signaling capability is implemented - maximum link speed is 8 GT/s per lane. This is confirmed in Section 1.2 "High-speed peripheral interfaces" of the LS2084A/LS2044A datasheet Rev. 4.
How many DDR4 ranks does the LS2044ASN711B support per channel?
The LS2044ASN711B supports up to two DDR4 ranks per channel (four total ranks across dual 64-bit controllers), as defined by its D1_MCS0_B–D1_MCS3_B chip select signals and documented rank addressing scheme. Each channel independently manages rank selection, timing, and refresh - enabling flexible memory configurations such as 2× RDIMMs or 4× UDIMMs with ECC.
Is the LS2044ASN711B pin-compatible with the LS2044ASE711B?
Yes, the LS2044ASN711B and LS2044ASE711B share identical 1292-ball FC-PBGA packaging, pinout, and mechanical footprint. The suffix difference (N vs. E) denotes different screening levels - 'N' indicates commercial temperature grade (0°C to 105°C), while 'E' denotes extended industrial grade (−40°C to 105°C) - but electrical and pin-level behavior is fully compatible.
What boot devices are supported by the LS2044ASN711B integrated flash controller?
The LS2044ASN711B integrated flash controller (IFC 2.0) supports parallel NOR flash (8-/16-bit), NAND flash (8-/16-bit with hardware ECC), and SPI NOR flash via QSPI interface. It does not support eMMC or SD card boot directly - those require the separate eSDHC controller. Boot configuration is set via hardware strapping pins (e.g., CFG_SPI_BOOT) and internal boot ROM executes from selected device per the LS2044A reference manual.
