NXP Semiconductors LS1022AXE7EKB

Overview

LS1022AXE7EKB from NXP is a dual-core ARM Cortex-A7 communications processor for power-sensitive industrial and networking applications, operating at up to 1.2 GHz with ECC-protected 32 KB L1 I/D caches per core and 512 KB coherent L2 cache, supporting DDR3L memory at up to 1033 MHz, and delivering over 7,000 CoreMarks® in sub-2 W typical system power. It integrates PCIe Gen2, triple Gigabit Ethernet with IEEE 1588, SATA 3.0, QuadSPI, CAN, and USB 2.0 interfaces.

For engineers reviewing the LS1022AXE7EKB datasheet, LS1022AXE7EKB pinout, LS1022AXE7EKB application, or LS1022AXE7EKB equivalent, key selection considerations include its 1.2 GHz dual Cortex-A7 core performance under 2 W, DDR3L memory controller limits, CAN interface support (absent on LS1020A), lack of QUICC Engine and USB 3.0, and suitability for fanless industrial gateways and secure IoT edge controllers.

Technical Context

The LS1022AXE7EKB implements a cache-coherent dual-core ARM Cortex-A7 subsystem connected via CCI-400 interconnect, with ECC protection across both L1 and L2 caches - a reliability feature distinguishing it within sub-3 W processors. Its memory subsystem supports only DDR3L (not DDR4) at up to 1033 MHz, and lacks the LS1020A's QUICC Engine and USB 3.0 PHY.

Networking is handled through a 4-lane 6 GHz SerDes supporting three 1 GbE ports with IEEE 1588 timestamping, two PCIe Gen2 lanes, and one SATA 3.0 interface; industrial connectivity includes four CAN controllers, six LP UARTs, and dual DUARTs - all confirmed for the LS1022A variant.

Key Specifications

Pinout & Package

LS1022AXE7EKB is housed in a 23 x 23 mm, 621-pin FC-BGA package (RoHS-compliant, Pb-free). Pin assignment follows the LS1022A reference schematic and layout guidelines; full pinout requires consultation of NXP document LS1022AFRM (Rev. 5), which defines signal multiplexing across 12 functional groups including DDR3L, SerDes, CANx, UARTx, I2C, SPI, and GPIO banks.

Supply support for LS1022AXE7EKB includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

NXP Semiconductors is a global semiconductor company headquartered in Eindhoven, Netherlands, specializing in secure connectivity solutions for automotive, industrial, and IoT markets.

The LS1022A processor belongs to NXP's QorIQ LS series, designed specifically to deliver high-performance, low-power ARM-based processing for secure, fanless industrial edge nodes with rich real-time I/O - especially where CAN, IEEE 1588, and hardware security are mandatory.

FAQ

What is the maximum DDR3L speed supported by LS1022AXE7EKB?

The LS1022AXE7EKB supports DDR3L memory at up to 1033 MHz (516 MHz clock frequency), as specified in the LS1022A Reference Manual (Rev. 5). This is lower than the LS1020A's 1600 MHz DDR3/DDR4 capability and reflects the LS1022A's focus on power efficiency over peak bandwidth. The memory controller is strictly DDR3L-only - DDR4 or standard DDR3 are not supported on LS1022AXE7EKB.

Does LS1022AXE7EKB include a USB 3.0 interface?

No, LS1022AXE7EKB does not include a USB 3.0 interface or integrated PHY. It provides only USB 2.0 functionality via a single high-speed USB 2.0 controller (480 Mbps). USB 3.0 is present on the LS1020A variant but omitted from the LS1022A family to reduce power and die area - consistent with its target use case in power-constrained industrial environments where USB 2.0 suffices for debug, firmware updates, or peripheral attachment.

How many CAN controllers are integrated into LS1022AXE7EKB?

The LS1022AXE7EKB integrates four independent CAN controllers, each capable of CAN FD operation up to 5 Mbps. These are fully implemented in silicon and do not require external IP blocks or software emulation. All four CAN modules support message filtering, FIFO buffering, and loopback self-test modes - enabling direct connection to CAN transceivers for industrial fieldbus consolidation without additional interface ICs.

Is QUICC Engine present in LS1022AXE7EKB?

No, the QUICC Engine is absent from LS1022AXE7EKB. It is included only in the LS1020A variant to support legacy HDLC, TDM, and ATM protocols. The LS1022A family replaces QUICC Engine functionality with software-managed peripherals and accelerated drivers for modern industrial protocols like CAN FD and Ethernet-based fieldbuses - aligning with its design goal of reducing power and complexity for next-generation edge applications.

What security features are hardware-accelerated in LS1022AXE7EKB?

LS1022AXE7EKB includes the QorIQ Security Engine (SEC) version 5.5, which hardware-accelerates AES-128/192/256 (ECB/CBC/CTR/GCM), SHA-1/SHA-224/SHA-256, RSA-1024/2048/3072/4096, and ECC (NIST P-256/P-384). It also supports Secure Boot with immutable ROM-based bootloader verification and ARM TrustZone for runtime isolation of secure world firmware - all confirmed in the LS1022A Security Reference Manual (AN5117).
