Product details
Overview
LS1023AXE7MQB from NXP Semiconductors is a dual-core, 64-bit ARM Cortex-A53 communications processor designed for embedded networking and industrial infrastructure. It delivers >10 Gb/s packet processing via DPAA offload engines, integrates a 1 MB L2 cache, supports DDR3L/DDR4 memory, and targets fanless branch office routers and industrial PLCs.
For engineers reviewing the LS1023AXE7MQB datasheet, LS1023AXE7MQB pinout, LS1023AXE7MQB application, or LS1023AXE7MQB equivalent, key selection factors include its dual-core 64-bit ARM architecture, integrated Frame Manager with IEEE 1588 support, SEC 5.4 security engine, SerDes-based multi-protocol I/O (up to 6× Gigabit Ethernet), and BOM-optimized low-layer PCB design capability.
Technical Context
The LS1023AXE7MQB implements two 64-bit ARM Cortex-A53 cores clocked up to 1.2 GHz, paired with a 1 MB shared L2 cache and CoreLink CCI-400 coherent interconnect. It integrates SMMU for hardware-enforced memory protection in virtualized environments and supports TrustZone for secure boot and runtime isolation.
Its networking subsystem includes a Frame Manager with hardware packet parsing, classification, and policing; a 4-lane 10 GHz SerDes supporting up to six Gigabit Ethernet ports with IEEE 1588 v2; and DPAA accelerators for zero-copy packet distribution and queue management - all enabling sub-10 µs latency for control-plane tasks.
Key Specifications

FAQ
What is the maximum operating frequency of the LS1023AXE7MQB?
The LS1023AXE7MQB operates at up to 1.2 GHz per ARM Cortex-A53 core. This frequency is guaranteed across industrial temperature range (–40°C to +105°C) with appropriate voltage scaling and thermal management. The LS1023AXE7MQB does not support dynamic frequency scaling beyond this rated speed, and overclocking is not validated or supported by NXP.
Does the LS1023AXE7MQB support DDR4 memory?
Yes, the LS1023AXE7MQB supports both DDR3L and DDR4 memory interfaces via its 32-bit memory controller. DDR4 operation is validated at data rates up to 2400 MT/s and requires specific PHY training sequences and voltage regulation (1.2 V). The LS1023AXE7MQB's DDR4 support enables higher bandwidth and lower active power than DDR3L in industrial gateway applications.
How many Gigabit Ethernet interfaces does the LS1023AXE7MQB support?
The LS1023AXE7MQB supports up to six Gigabit Ethernet interfaces through its integrated Frame Manager and 4-lane 10 GHz SerDes. These can be configured as six independent 1 GbE ports, or combined into fewer ports using SGMII, RGMII, or QSGMII PHYs. IEEE 1588 v2 timestamping is supported on all six ports for time-critical industrial networking.
Is the LS1023AXE7MQB pin-compatible with the LS1043AXE7MQB?
No, the LS1023AXE7MQB is not pin-compatible with the LS1043AXE7MQB. Although both use the same 621-pin FC-BGA package footprint, key signal assignments differ - including SerDes lane mapping, PCIe root complex vs. endpoint configurations, and security engine clock routing. Board-level redesign is required when migrating between these two processors.
What boot sources are supported by the LS1023AXE7MQB?
The LS1023AXE7MQB supports boot from QuadSPI Flash, IFC-connected NAND/NOR Flash, SD/eMMC, and USB mass storage devices. Boot mode is selected via BOOT_CFG[0:7] strapping pins at reset. The LS1023AXE7MQB executes secure boot from ROM, verifying signed images before loading firmware - a mandatory step enforced by its TrustZone-enabled boot ROM.
