Product details
Overview
LS1020AXN7MQB from NXP is a dual-core ARM Cortex-A7 communications processor for power-sensitive networking and industrial applications, operating up to 1.2 GHz with ECC-protected 512 KB L2 cache, 7,000+ CoreMarks® performance, and integrated security engine supporting Secure Boot and ARM TrustZone. It integrates PCIe 2.0, triple Gigabit Ethernet with IEEE 1588, SATA 3.0, USB 3.0 with PHY, and QUICC Engine for HDLC/TDM protocols.
For engineers reviewing the LS1020AXN7MQB datasheet, LS1020AXN7MQB pinout, LS1020AXN7MQB application, or LS1020AXN7MQB equivalent, key selection criteria include sub-3 W thermal envelope, DDR3L/DDR4 memory controller support, hardware virtualization capability, and industrial protocol acceleration via QUICC Engine - all confirmed for this exact LS1020A variant.
Technical Context
The LS1020AXN7MQB implements a cache-coherent dual-core ARM Cortex-A7 subsystem with CCI-400 interconnect, ECC on both L1 (32 KB I/D per core) and L2 (512 KB shared), and NEON SIMD + dual-precision FPU per core. Its SerDes supports three configurable high-speed interfaces: PCIe 2.0 (dual x1), SATA 3.0, and triple 1 GbE with IEEE 1588 timestamping.
Security is implemented via QorIQ SEC 5.5 hardware engine enabling AES/SHA/RSA acceleration, Secure Boot from internal ROM or QuadSPI, and ARM TrustZone partitioning. Power management includes dynamic voltage/frequency scaling and multiple low-power states coordinated by dedicated system control unit.

Equivalent & Alternatives
The following parts are listed as comparable options for similar communications processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LS1022ASN7MQB | Same dual Cortex-A7 core but capped at 600 MHz; DDR3L only (no DDR4); no USB 3.0 or QUICC Engine; adds 4× CAN controllers. | Better suited for CAN-heavy industrial control where cryptographic acceleration and high-speed USB are unnecessary. | Select LS1022ASN7MQB when CAN protocol support outweighs need for USB 3.0, SATA, or QUICC Engine - especially in cost- and power-constrained factory floor nodes. |
| i.MX 6SoloX MCIMX6SXNNCZ8 | Single Cortex-A9 + Cortex-M4 heterogeneous core; no PCIe, no SATA, no QUICC Engine; includes Vivante GC320 GPU; lower CoreMark score (~5,000). | Targeted at HMI-rich industrial displays with real-time control, not high-throughput packet processing or protocol bridging. | Choose i.MX 6SoloX when GUI rendering and deterministic M4-based motor control dominate over networking throughput and industrial protocol offload. |
Compared with LS1022ASN7MQB and i.MX 6SoloX, the LS1020AXN7MQB uniquely combines PCIe 2.0, USB 3.0, SATA 3.0, and QUICC Engine in a sub-3 W package - making it the only option among the three for converged edge routers requiring hardware-accelerated crypto, time-sensitive networking, and legacy serial protocol bridging.

FAQ
What is the maximum DDR memory speed supported by LS1020AXN7MQB?
The LS1020AXN7MQB supports DDR3L and DDR4 memory at data rates up to 1600 MT/s. This is achieved through its integrated memory controller with programmable timing parameters and on-die termination calibration. The LS1020AXN7MQB datasheet specifies 1600 MT/s as the maximum validated rate for both DDR3L and DDR4 configurations, enabling high-bandwidth data movement essential for concurrent networking and security workloads.
Does LS1020AXN7MQB include hardware support for IEEE 1588 Precision Time Protocol?
Yes, LS1020AXN7MQB includes full hardware timestamping support for IEEE 1588 v2 across all three integrated Gigabit Ethernet MACs. Each MAC features dedicated timestamp registers and hardware-assisted packet insertion/removal of PTP fields, enabling sub-microsecond time synchronization accuracy in industrial automation and telecom timing applications without CPU intervention.
Can LS1020AXN7MQB operate without an external PHY for Ethernet connectivity?
No, LS1020AXN7MQB does not integrate Ethernet PHYs; it provides only MAC-layer interfaces (RGMII/SGMII). External PHYs are required for physical layer connectivity. However, the LS1020AXN7MQB's MACs support reduced-pin-count RGMII with internal delay compensation, simplifying layout and reducing component count compared to GMII implementations.
Is QUICC Engine present in all LS1020A variants including LS1020AXN7MQB?
Yes, QUICC Engine is a standard feature across all LS1020A variants, including LS1020AXN7MQB. It is a dedicated RISC coprocessor supporting HDLC, TDM, and packet buffer management, and is explicitly documented in the LS1020A reference manual and block diagrams as integral to the LS1020AXN7MQB silicon die.
What development tools are officially supported for LS1020AXN7MQB software bring-up?
NXP officially supports CodeWarrior Development Suite for Networked Applications (Developer Suite Level) and the Linux SDK based on kernel 3.12 for LS1020AXN7MQB. The TWR-LS1021A evaluation platform - though named for LS1021A - is compatible with LS1020AXN7MQB via pin-compatible socket and shared software stack, providing validated boot flow and peripheral drivers out of the box.
