Product details
Overview
LS1022ASN7EKB from NXP is a dual-core ARM Cortex-A7 communications processor for power-sensitive networking and industrial applications, operating at up to 1.2 GHz (600 MHz typical), delivering >7,000 CoreMarks®, supporting DDR3L memory at up to 1033 MHz, and integrating ECC-protected L1/L2 caches with 512 KB coherent L2 cache. It serves as the main application processor in IoT gateways and building automation controllers.
For engineers reviewing the LS1022ASN7EKB datasheet, LS1022ASN7EKB pinout, LS1022ASN7EKB application, or LS1022ASN7EKB equivalent, key selection considerations include its 600 MHz dual Cortex-A7 core speed, CAN interface support, sub-2 W typical system power, DDR3L memory controller limits, and industrial protocol readiness via 4× CAN and 8× UART.
Technical Context
The LS1022ASN7EKB implements two ARM Cortex-A7 cores with NEON SIMD and dual-precision FPU, each with 32 KB L1 instruction/data cache and shared 512 KB coherent L2 cache featuring single-bit error detection and correction. Cache coherency is maintained via ARM CCI-400 interconnect.
It integrates a 1-lane 5 GHz SerDes supporting PCIe Gen2, three I²C and two SPI interfaces, four CAN controllers, six low-power UARTs plus two DUARTs, and a DDR3L memory controller rated for 1033 MHz across up to four devices - all while maintaining typical system power under 2 W.

Equivalent & Alternatives
The following parts are listed as comparable options for similar communications processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LS1021ASN7KQB | Single-core ARM Cortex-A7 at 1.0 GHz, no CAN controllers, includes QUICC Engine for HDLC/TDM | Better suited for legacy telecom line cards requiring HDLC framing, not industrial CAN networks | Select when QUICC Engine protocol acceleration is required and CAN is unnecessary |
| i.MX 6ULL G0 | Single-core Cortex-A7 at 900 MHz, no CAN, no PCIe, lower integration (no hardware crypto engine) | Targeted at cost-sensitive HMI and basic IoT endpoints, not multi-protocol edge gateways | Select for simpler UI-focused designs where CAN, PCIe, and hardware security are not needed |
Compared with LS1021ASN7KQB and i.MX 6ULL G0, the LS1022ASN7EKB uniquely combines dual Cortex-A7 performance, 4× CAN, PCIe Gen2, and hardware crypto in a sub-2 W envelope - making it the only option among the three for compact, secure, multi-protocol industrial gateways.

FAQ
What is the maximum DDR3L speed supported by LS1022ASN7EKB?
The LS1022ASN7EKB supports DDR3L memory at up to 1033 MHz across an 8/16/32-bit bus with up to four memory devices. This limit is fixed in silicon and cannot be exceeded even with optimized PCB layout or voltage tuning. The LS1022ASN7EKB does not support DDR4 or standard DDR3 - only DDR3L (1.35 V).
Does LS1022ASN7EKB include hardware support for CAN FD?
Yes, LS1022ASN7EKB integrates four fully independent CAN controllers compliant with ISO 11898-1:2015, supporting Classical CAN and CAN FD modes up to 5 Mbps. Each controller includes dedicated message RAM, filtering, and loopback self-test capability - no external CAN transceiver is required for basic operation.
Is LS1022ASN7EKB pin-compatible with LS1020A or LS1021A processors?
No, LS1022ASN7EKB is not pin-compatible with LS1020A or LS1021A. It uses a distinct 621-ball FC-BGA package (SN7E) with different power, clock, and I/O ball assignments. Migration requires PCB redesign; refer to NXP's LS1022A Hardware Design Guide for layout constraints.
What boot sources are supported by LS1022ASN7EKB?
LS1022ASN7EKB supports boot from QuadSPI flash, SD/MMC card, or IFC-connected NAND/NOR flash via configurable BOOT_CFG pins. Internal boot ROM provides initial code execution and secure boot validation before loading the primary image - no external boot EEPROM or PROM is required.
Does LS1022ASN7EKB include a hardware virtualization extension?
Yes, LS1022ASN7EKB includes ARM Virtualization Extensions (VirtExt) enabling hypervisor-based partitioning of CPU resources. This allows simultaneous execution of real-time industrial control tasks and general-purpose Linux services - validated with Wind River Helix Virtualization Platform and NXP's QorIQ SDK.
