Product details
Overview
LS1043ASE8PQB 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 (1.6 GT/s), DPAA hardware acceleration for packet processing, and integrated security engine (SEC). It targets network edge infrastructure including industrial gateways and wireless access points.
For engineers reviewing the LS1043ASE8PQB datasheet, LS1043ASE8PQB pinout, LS1043ASE8PQB application, or LS1043ASE8PQB equivalent, key selection criteria include SerDes lane configuration (PCIe 2.0 x4, SATA 3.0, SGMII up to 2.5G), IEEE 1588 timestamping support, TrustZone-enabled secure boot, and thermal design power (TDP) of 12 W in typical operation.
Technical Context
The LS1043ASE8PQB implements a CCI-400™ coherency interconnect fabric enabling hardware-managed cache coherency across four Cortex-A53 cores at up to 400 MHz. Its Data Path Acceleration Architecture (DPAA) offloads packet parsing, classification, queue management (QMan), buffer allocation (BMan), and cryptography (SEC) from the CPU.
It integrates a 32-bit DDR4/DDR3L SDRAM controller with ECC and interleaving support, dual RGMII Ethernet interfaces with IEEE 1588v2 hardware timestamping, and four high-speed SerDes lanes configurable for PCIe 2.0, SATA 3.0, SGMII (1G/2.5G), XFI (10G), or QSGMII.

Equivalent & Alternatives
The following parts are listed as comparable options for similar networking SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LS1023ASE7KQB | Dual-core Cortex-A53, no XFI support, lower TDP (7 W), same pinout footprint but reduced SerDes flexibility. | Targeted at cost-sensitive SD-WAN CPE where 10G uplink is unnecessary and thermal envelope is constrained. | Select when application requires only 1G/2.5G Ethernet and <10 W power budget; not drop-in due to missing SEC acceleration features. |
| IMX8MQXCVADHR | Quad Cortex-A53 + dual Cortex-M4F, no DPAA, no hardware 1588, MIPI-CSI/DSI interfaces instead of SerDes. | Optimized for multimedia edge AI (e.g., vision-based industrial inspection) rather than packet-forwarding or telecom control planes. | Choose for heterogeneous compute (Linux + RTOS) with camera/display I/O; lacks networking acceleration blocks required for LS1043ASE8PQB use cases. |
Compared with LS1023ASE7KQB and IMX8MQXCVADHR, LS1043ASE8PQB uniquely combines full DPAA offload, XFI-capable SerDes, and SEC-based IPsec acceleration-making it the only option among the three for carrier-grade 10G edge routing with hardware-enforced security.

FAQ
What is the maximum DDR4 data rate supported by LS1043ASE8PQB?
The LS1043ASE8PQB supports DDR4/DDR3L memory at up to 1.6 GT/s (effective 3200 MT/s for DDR4-3200), with 32-bit bus width and ECC capability. This enables sustained memory bandwidth of 6.4 GB/s, sufficient for concurrent packet buffering, crypto operations, and application execution in LS1043ASE8PQB-based gateways.
Does LS1043ASE8PQB support IEEE 1588 Precision Time Protocol in hardware?
Yes, LS1043ASE8PQB provides full hardware IEEE 1588v2 timestamping on both RGMII and SGMII Ethernet interfaces, with programmable timestamp insertion/removal and sub-100 ns resolution. This capability is integral to LS1043ASE8PQB's role in time-sensitive industrial networking and substation automation systems.
Can LS1043ASE8PQB boot directly from eMMC 4.5 devices?
Yes, LS1043ASE8PQB's integrated eSDHC controller supports eMMC 4.5 boot modes including HS400 (200 MHz DDR), enabling fast, reliable boot from embedded flash without external boot ROM. This feature simplifies system design and improves boot-time predictability in LS1043ASE8PQB deployments.
What SerDes configurations are supported on LS1043ASE8PQB?
LS1043ASE8PQB's 4-lane SerDes supports PCIe 2.0 x4, SATA 3.0, SGMII (1G/2.5G), XFI (10G), QSGMII, and 1000Base-KX. Configuration is done via RCW (Reset Configuration Word) fuses; each lane is independently assignable, allowing mixed-mode usage such as PCIe + SATA + SGMII in a single LS1043ASE8PQB design.
Is LS1043ASE8PQB pin-compatible with other QorIQ LS10xx devices?
No, LS1043ASE8PQB is not pin-compatible with LS1023A or LS1046A. While sharing the same 621-ball FC-PBGA package outline, LS1043ASE8PQB has unique ball mapping-especially for DDR, SerDes, and I/O voltage domains-requiring dedicated PCB layout. Migration between LS10xx variants necessitates board redesign.
