NXP Semiconductors LS2044ASN7QQB

Overview

LS2044ASN7QQB from NXP Semiconductors is a quad-core Arm® Cortex®-A72 SoC designed for control and data-path processing in networking, telecom, and automotive gateways. It integrates four A72 cores (two dual-core clusters), 1 MB platform cache with ECC, dual 64-bit DDR4 controllers (up to 2.1 GT/s), DPAA2 acceleration, and 16 SerDes lanes supporting up to 10.3125 GHz - deployed in vehicle management servers and ADAS domain controllers.

For engineers reviewing the LS2044ASN7QQB datasheet, LS2044ASN7QQB pinout, LS2044ASN7QQB application, or LS2044ASN7QQB 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 x8/x4/x2/x1 capability with SR-IOV on one controller.

Technical Context

The LS2044ASN7QQB implements a hierarchical interconnect fabric linking two dual-core Cortex-A72 clusters, each sharing 1 MB L2 cache, with coherent I/O and memory subsystems. Its DPAA2 architecture offloads packet parsing, queue management (QBMan), cryptography (SEC 5.2 at 20 Gbps), RegEx (PME 2.0 at 10 Gbps), and compression (DCE 1.0 at 20 Gbps) from CPU cores.

It supports two DDR4 memory controllers with ECC, interleaving, and up to 2.1 GT/s data rates; four PCIe 3.0 controllers (one with SR-IOV); eight 10G/16×1–2.5G Ethernet MACs; and SerDes lanes configurable for PCIe, SATA, USB 3.0, or SGMII. Platform clocking includes differential SYSCLK input and integrated PLLs for SerDes and DDR timing.

Key Specifications

Pinout & Package

LS2044ASN7QQB uses a 1292-ball FC-PBGA package (35 mm × 35 mm, 0.8 mm pitch) with thermal lid and exposed die paddle. Pin assignments are organized across DDR, SerDes, PCIe, Ethernet, USB, and system control domains - full ball map and signal-level pinout defined in NXP Document Number LS2084A Rev. 4.

FAQ

What is the maximum DDR4 data rate supported by LS2044ASN7QQB?

The LS2044ASN7QQB supports up to 2.1 GT/s on both DDR4 memory controllers under standard operating conditions. In AEC-Q100 Grade 3 mode (105°C Tj), the maximum DDR4 data rate is reduced to 1.8 GT/s to maintain signal integrity and timing margin across the extended temperature range. This is explicitly specified in Section 3.8 of the LS2084A/LS2044A Data Sheet Rev. 4.

Does LS2044ASN7QQB support PCIe 3.0 SR-IOV, and on which controller?

Yes, LS2044ASN7QQB supports PCIe 3.0 SR-IOV exclusively on the PCIe3 controller. The other three PCIe controllers (PCIe1, PCIe2, PCIe4) support only x4/x2/x1 widths and do not implement SR-IOV functionality. This configuration is fixed in silicon and documented in the "High-speed peripheral interfaces" section of the LS2084A/LS2044A Data Sheet.

How is hardware security implemented in LS2044ASN7QQB?

LS2044ASN7QQB implements a layered hardware security architecture: TrustZone® enforces secure/non-secure world isolation; a dedicated service processor (SP) handles pre-boot initialization and secure boot; security fuses and a battery-backed security monitor provide tamper resistance; and SEC 5.2 delivers cryptographic acceleration for AES, SHA, RSA, and ECC operations at up to 20 Gbps. All elements are integral to the LS2044ASN7QQB silicon design.

What SerDes protocols can be configured on LS2044ASN7QQB's 16 lanes?

The 16 SerDes lanes of LS2044ASN7QQB support PCIe 3.0, SATA 3.0, USB 3.0, SGMII, XAUI, and CPRI/eCPRI protocols - subject to lane grouping constraints and reference clock availability. Configuration is performed via RCW (Reset Configuration Word) and SerDes initialization firmware, with protocol mapping defined in the LS2084A/LS2044A Data Sheet Section 2.2 and Application Note AN5407.

Is LS2044ASN7QQB pin-compatible with LS2084ASN7QQB?

No, LS2044ASN7QQB is not pin-compatible with LS2084ASN7QQB. Although both use the same 1292-ball FC-PBGA package footprint, their pin functions differ significantly - particularly in DDR address/control allocation, SerDes lane assignment, and PCIe reference clock routing. Board-level reuse requires redesign per the respective pinout lists in Tables 1–4 of the LS2084A/LS2044A Data Sheet.
