Product details
Overview
LS1021ASE7MQB from NXP is a dual-core ARM Cortex-A7 communications processor with ECC-protected L1/L2 caches, 512 KB coherent L2 cache, DDR3L/4 memory controller (up to 1600 MHz), and integrated QUICC Engine for industrial protocol support. It delivers 7,000+ CoreMarks® at ≤3 W typical system power and targets fanless networked edge devices requiring virtualization, security, and rich I/O.
For engineers reviewing the LS1021ASE7MQB datasheet, LS1021ASE7MQB pinout, LS1021ASE7MQB application, or LS1021ASE7MQB equivalent, key selection criteria include its dual Cortex-A7 cores with NEON/FPU, SEC 5.5 security engine, four CAN interfaces, IEEE 1588-capable triple Gigabit Ethernet, PCIe Gen2 x2, SATA 3.0, USB 3.0 + USB 2.0, and LCD controller with 2D-ACE.
Technical Context
The LS1021ASE7MQB implements a cache-coherent interconnect (CCI-400) linking dual Cortex-A7 cores, 512 KB L2 cache, and accelerators including QUICC Engine (HDLC/TDM/PB), SEC 5.5 crypto engine, and ASRC/SPDIF audio subsystem. It supports hardware-assisted virtualization for resource partitioning across secure and non-secure domains.
Its 4-lane 6 GHz SerDes enables concurrent configuration of three Gigabit Ethernet ports (with IEEE 1588 timestamping), two PCIe Gen2 links, and one SATA 3.0 interface. Memory subsystem includes DDR3L/DDR4 support up to 1600 MHz with 8/16/32-bit bus width and integrated ECC protection on both L1 and L2 caches.

Equivalent & Alternatives
The following parts are listed as comparable options for similar communications processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LS1021AST7MQB | Same die, higher temperature grade (–40°C to +105°C vs –40°C to +125°C); identical pinout and feature set | Targeted at extended-temperature industrial environments where ambient exceeds 105°C | Select LS1021AST7MQB only when full 125°C junction operation is required; otherwise LS1021ASE7MQB suffices for most fanless deployments |
| i.MX 6SoloX MCIMX6SX5AVO08AB | Single ARM Cortex-A9 + Cortex-M4 dual-core; no QUICC Engine; no PCIe/SATA; lower CoreMark score (~5,200) | Better suited for HMI-centric embedded control than networking-intensive gateways | Choose i.MX 6SoloX only when M4 real-time co-processor is mandatory and networking bandwidth requirements are sub-Gigabit |
Compared with LS1021AST7MQB, the LS1021ASE7MQB offers identical functionality at a lower thermal rating-ideal for cost-sensitive, thermally managed fanless systems. Against i.MX 6SoloX, LS1021ASE7MQB provides superior networking throughput, hardware security acceleration, and industrial protocol offload, making it the preferred choice for secure, multi-protocol edge gateways.

FAQ
What is the maximum operating frequency of the LS1021ASE7MQB?
The LS1021ASE7MQB features dual ARM Cortex-A7 cores rated for operation up to 1.2 GHz. This frequency is guaranteed under specified thermal and voltage conditions per NXP's LS1021AFS REV 6 datasheet. The processor dynamically adjusts clock speed based on workload and thermal headroom, but 1.2 GHz represents its peak sustained performance ceiling for both cores simultaneously.
Does the LS1021ASE7MQB support DDR4 memory?
Yes, the LS1021ASE7MQB supports DDR4 memory at data rates up to 1600 MHz, in addition to DDR3L. Its memory controller is configurable for 8-, 16-, or 32-bit bus widths and includes full ECC protection across all supported DDR generations. This DDR4 capability extends memory bandwidth and density options for next-generation edge applications while maintaining backward compatibility.
How many CAN interfaces does the LS1021ASE7MQB integrate?
The LS1021ASE7MQB integrates four independent CAN 2.0B controllers, each with dedicated TX/RX signal pairs and configurable bit rates up to 1 Mbps. These are fully supported in NXP's Linux SDK and can operate concurrently-enabling multi-bus industrial automation, vehicle telematics, or smart building control without external CAN transceivers beyond physical layer drivers.
Is the LS1021ASE7MQB pin-compatible with other LS1021A variants?
Yes, all LS1021A variants-including LS1021ASE7MQB, LS1021AST7MQB, and LS1021AT7MQB-share identical 621-ball PBGA packaging and pinout. Differences are limited to temperature grade, speed binning, and internal fuse settings; no PCB redesign is needed when migrating between these variants during qualification or volume production.
What development tools are officially supported for the LS1021ASE7MQB?
NXP officially supports the LS1021ASE7MQB with the TWR-LS1021A Tower evaluation board, Linux SDK 3.12+, CodeWarrior Development Studio for Networked Applications (with 90-day evaluation license), and Layerscape Software Development Kit. Debugging uses JTAG via the onboard probe, and boot images are configured through BOOT_CFG strapping pins per the LS1021AFS specification.
