Product details
Overview
LS1043ASE7QQA from NXP Semiconductors is a quad-core 64-bit ARM Cortex-A53 communications processor targeting embedded networking and industrial infrastructure. It delivers up to 10 Gb/s packet processing via DPAA, integrates SEC 5.4 for IPsec/SSL acceleration, and supports DDR4 memory with 1 MB L2 cache-used in vCPE, industrial PLCs, and multi-protocol IoT gateways.
For engineers reviewing the LS1043ASE7QQA datasheet, LS1043ASE7QQA pinout, LS1043ASE7QQA application, or LS1043ASE7QQA equivalent, key selection factors include its 4×1.6 GHz CPU cores, Frame Manager–based hardware packet parsing, PCIe Gen2 ×3, six Gigabit Ethernet ports with IEEE 1588, and QUICC Engine support for HDLC/TDM/PROFIBUS.
Technical Context
The LS1043ASE7QQA implements a coherent CoreLink CCI-400 interconnect with SMMU for virtualized I/O memory management, enabling secure resource partitioning across VMs. Its DPAA offloads packet classification, distribution, policing, and IP reassembly from CPU cores-reducing software overhead while sustaining line-rate throughput on up to six 1 GbE interfaces.
It integrates a 4-lane 10 GHz multi-protocol SerDes supporting SGMII, XFI, SATA 3.0, and PCIe Gen2; triple USB 3.0 controllers with PHY; and a dedicated uQE engine for legacy protocol handling (HDLC, TDM, PROFIBUS) without external glue logic.

FAQ
What is the maximum operating frequency of the LS1043ASE7QQA?
The LS1043ASE7QQA operates at up to 1.6 GHz per ARM Cortex-A53 core. This frequency is guaranteed under thermal and voltage conditions specified in the LS1043A Data Sheet Rev. 6. The LS1043ASE7QQA maintains this speed across all four cores simultaneously when configured with adequate cooling and DDR4 memory bandwidth-critical for sustained packet forwarding in branch office routers.
Does the LS1043ASE7QQA support DDR4 memory?
Yes, the LS1043ASE7QQA supports both DDR3L and DDR4 memory interfaces. It was the first value-tier QorIQ processor to integrate a DDR4 controller, enabling 1600 MT/s operation. This capability is confirmed in the LS1043A Reference Manual and validated in NXP's LS1043A-RDB design-allowing LS1043ASE7QQA-based systems to scale memory bandwidth while maintaining low-power operation.
How many Gigabit Ethernet interfaces does the LS1043ASE7QQA support?
The LS1043ASE7QQA supports up to six Gigabit Ethernet interfaces, each with IEEE 1588v2 timestamping. These are implemented via the integrated Frame Manager and SerDes lanes, configurable as SGMII, RGMII, or QSGMII. This configuration is used in LS1043ASE7QQA-based industrial gateways to concurrently manage factory floor networks, SCADA uplinks, and diagnostic ports without external switches.
Is the QUICC Engine present in the LS1043ASE7QQA?
Yes, the LS1043ASE7QQA includes the QUICC Engine (uQE) subsystem, which provides dedicated hardware for HDLC, TDM, and PROFIBUS protocol handling. Unlike software-based implementations, the uQE in LS1043ASE7QQA operates independently of the ARM cores-enabling deterministic timing and zero-CPU-overhead communication with legacy industrial fieldbus devices.
What security features are integrated into the LS1043ASE7QQA?
The LS1043ASE7QQA integrates Security Engine (SEC) version 5.4, supporting IPsec, SSL/TLS, DTLS, IKE, and high-speed XOR for RAID 5. It also includes TrustZone-enabled secure boot and SMMU-based I/O memory protection. These features are documented in the LS1043A Security Reference Manual and enable LS1043ASE7QQA to serve as the root of trust in vCPE and security appliance designs.
