Product details
Overview
LS1043ASE7QQB from NXP Semiconductors is a quad-core 64-bit ARM Cortex-A53 communications processor with 1 MB L2 cache, integrated Data Path Acceleration Architecture (DPAA), and support for up to six Gigabit Ethernet ports with IEEE 1588 timing. It delivers up to 10 Gb/s packet processing performance for fanless edge networking equipment.
For engineers reviewing the LS1043ASE7QQB datasheet, LS1043ASE7QQB pinout, LS1043ASE7QQB application, or LS1043ASE7QQB equivalent, key selection criteria include DDR3L/DDR4 memory controller compatibility, SEC 5.4 security engine capability, CoreLink CCI-400 coherency fabric, PCIe Gen 2 interface count, and QUICC Engine support for legacy TDM/HDLC protocols.
Technical Context
The LS1043ASE7QQB implements four ARM Cortex-A53 cores operating at up to 1.6 GHz, each with 32 KB I-cache and 32 KB D-cache, backed by a shared 1 MB L2 cache and CoreLink CCI-400 interconnect with SMMU for hardware-enforced I/O memory management. Its DPAA offload engines handle packet parsing, classification, and policing in hardware.
Networking interfaces include a 4-lane 10 GHz multi-protocol SerDes supporting up to six 1 GbE ports (with IEEE 1588), three PCIe Gen 2 controllers, one SATA 3.0 controller, and triple USB 3.0 with integrated PHY. The integrated QUICC Engine supports glueless HDLC, TDM, and PROFIBUS without external logic.

Equivalent & Alternatives
The following parts are listed as comparable options for similar communications processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LS1023ASE7KK | Dual-core Cortex-A53, no QUICC Engine, lower L2 cache (512 KB), fewer PCIe lanes (2×) | Targeted at lighter-duty vCPE or basic IoT gateways without legacy serial protocol requirements | Select when BOM cost and thermal envelope are prioritized over protocol flexibility and packet throughput |
| IMX8MQXCVKHAZ | Quad-core Cortex-A53 + dual Cortex-M4, no DPAA, no SEC, no QUICC Engine, but includes GPU and MIPI-CSI | Optimized for multimedia-rich HMI and vision-enabled edge devices-not networking or industrial protocol gateways | Select only if display, camera, or real-time M4 co-processing outweighs networking acceleration and security engine needs |
Compared with LS1023ASE7KK and i.MX8MQXCVKHAZ, the LS1043ASE7QQB uniquely combines QUICC Engine legacy support, DPAA packet acceleration, and SEC 5.4 in a single 64-bit SoC-making it the only option among the three for secure, high-throughput, multi-protocol industrial edge gateways requiring both modern IP and legacy fieldbus connectivity.

FAQ
What is the maximum operating frequency of the LS1043ASE7QQB?
The LS1043ASE7QQB features four ARM Cortex-A53 cores rated for operation up to 1.6 GHz. This frequency is validated under thermal and voltage conditions specified in the LS1043AFS Rev 6 datasheet, and sustained operation requires adherence to the recommended PCB layout, power delivery, and thermal dissipation guidelines for the 780-pin FC-BGA package.
Does the LS1043ASE7QQB support DDR4 memory?
Yes, the LS1043ASE7QQB integrates a 32-bit DDR3L/DDR4 memory controller supporting both DDR3L (1.35 V) and DDR4 (1.2 V) DRAM. DDR4 support enables higher bandwidth and lower power per bit compared to DDR3L, and is confirmed in the Memory Controller chapter of the LS1043AFS Rev 6 reference manual.
What networking interfaces are integrated into the LS1043ASE7QQB?
The LS1043ASE7QQB integrates a 4-lane 10 GHz SerDes supporting up to six 1 GbE ports (with IEEE 1588 v2), three PCIe Gen 2.0 controllers, one SATA 3.0 controller, triple USB 3.0 with PHY, QuadSPI, IFC, SD/eMMC, and QUICC Engine for HDLC/TDM/PROFIBUS-all documented in the LS1043AFS Rev 6 System Interfaces chapter.
Is the LS1043ASE7QQB pin-compatible with other QorIQ LS series processors?
No, the LS1043ASE7QQB is not pin-compatible with LS1023A or LS1088A processors. Its 780-pin FC-BGA footprint, power rail allocation, and signal multiplexing are unique to the LS1043A family. Migration between LS series devices requires PCB redesign, as confirmed in the LS1043AFS Rev 6 pinout comparison tables.
What security features does the LS1043ASE7QQB include?
The LS1043ASE7QQB includes Secure Boot with immutable ROM code, ARM TrustZone for hardware-isolated secure world execution, and the integrated Security Engine (SEC) version 5.4 supporting IPsec, SSL/TLS, DTLS, IKE, and XOR acceleration for RAID 5-all verified in the LS1043AFS Rev 6 Security chapter and supported by NXP's Code Signing Toolchain.
