Product details
Overview
LS1043ACE9QQB from NXP Semiconductors is a quad-core 64-bit Arm® Cortex®-A53 system-on-chip (SoC) operating up to 1.6 GHz, featuring 1 MB ECC-protected L2 cache, DDR4/DDR3L memory controller with ECC support, and integrated Data Path Acceleration Architecture (DPAA) for packet processing, cryptography (SEC), and queue/buffer management. It targets network edge infrastructure including industrial gateways and enterprise routers.
For engineers reviewing the LS1043ACE9QQB datasheet, LS1043ACE9QQB pinout, LS1043ACE9QQB application, or LS1043ACE9QQB equivalent, this page delivers verified core architecture, SerDes interface capabilities (PCIe 2.0 x4, SATA 3.0, SGMII up to 2.5 GbE), hardware-accelerated networking functions, and package-specific ball mapping for FC-PBGA 621-pin layout.
Technical Context
The LS1043ACE9QQB implements a CCI-400™ coherency interconnect fabric enabling hardware-managed cache coherency across four Cortex-A53 cores at up to 400 MHz. Its DPAA subsystem integrates Frame Manager (FMan), Queue Manager (QMan), Buffer Manager (BMan), and Security Engine (SEC) for deterministic packet classification, scheduling, and cryptographic acceleration (AES, SHA, RSA).
It supports parallel Ethernet via two RGMII interfaces with IEEE 1588 timestamping, and four SerDes lanes configurable as PCIe 2.0 (x4), SATA 3.0, SGMII (1G/2.5G), XFI (10G), or QSGMII - all operating from a single 10 GHz SerDes PLL. Memory subsystem includes 32 KB I/D L1 caches with parity/ECC and unified 1 MB L2 cache with ECC.
