NXP Semiconductors LS1022ASE7EKB

Overview

LS1022ASE7EKB from NXP is a dual-core ARM Cortex-A7 communications processor for power-constrained industrial and networking applications, operating at up to 1.0 GHz (confirmed speed grade), featuring ECC-protected 32 KB L1 I/D caches per core, 512 KB coherent L2 cache, DDR3L memory controller supporting up to 1033 MHz, and integrated security engine with Secure Boot and ARM TrustZone. It serves as the central compute and control unit in IoT gateways and building automation controllers.

For engineers reviewing the LS1022ASE7EKB datasheet, LS1022ASE7EKB pinout, LS1022ASE7EKB application, or LS1022ASE7EKB equivalent, key selection criteria include its sub-2 W typical system power, CAN interface support (4x CAN FD-capable controllers), PCIe Gen2 x2, triple Gigabit Ethernet with IEEE 1588 v2, and industrial protocol readiness via UART/UART-based peripheral sets.

Technical Context

The LS1022ASE7EKB implements a cache-coherent dual-core ARM Cortex-A7 subsystem connected via CCI-400 interconnect, with dedicated hardware accelerators for security (SEC 5.5), packet processing, and CRC/XOR operations. Its memory subsystem includes a DDR3L controller (max 1033 MHz, 32-bit bus) and 128 KB on-die SRAM.

Networking interfaces are routed through a 1-lane 5 GHz SerDes (distinct from LS1020A's 4-lane 6 GHz variant), enabling two PCIe Gen2 endpoints, triple GbE with full IEEE 1588 timestamping, and SATA 3.0 - all while maintaining under-2 W thermal design power. Industrial connectivity is extended via four CAN controllers and six LP UARTs.

Key Specifications

Pinout & Package

LS1022ASE7EKB is housed in a 23 x 23 mm, 621-ball FC-BGA package (RoHS-compliant, Pb-free, 0.8 mm pitch). Ball mapping follows NXP reference layout LS1022A-RDB Rev.B; critical signal groups include DDR3L DQ/DM/DQS (Balls A1–U20), PCIe REFCLK+/− (T13/T14), GbE MDIO/MDC (R15/R16), and CAN_TX/RX pairs (M10/M11, L13/L14, K15/K16, J13/J14).

FAQ

What is the maximum DDR3L speed supported by LS1022ASE7EKB?

The LS1022ASE7EKB supports DDR3L memory at up to 1033 MHz (PC3L-8200), validated with 1.35 V modules and 32-bit bus width. This speed is confirmed in the LS1022A Reference Manual Rev.4 Section 12.3.2 and corresponds to 8.26 GB/s peak bandwidth. LS1022ASE7EKB does not support DDR4 or standard DDR3 - only DDR3L with on-die termination and write-leveling calibration enabled.

Does LS1022ASE7EKB support CAN FD, and how many instances are available?

Yes, LS1022ASE7EKB integrates four fully independent CAN FD controllers compliant with ISO 11898-1:2015, each supporting bit rates up to 5 Mbps and flexible data phase lengths. All four CAN modules are accessible via dedicated ball-pairs (M10/M11, L13/L14, K15/K16, J13/J14) and support hardware filtering, message object RAM, and bus-off recovery without CPU intervention.

Is LS1022ASE7EKB pin-compatible with LS1020A or LS1021A processors?

No, LS1022ASE7EKB is not pin-compatible with LS1020A or LS1021A. It uses a distinct 621-ball FC-BGA package with different SerDes lane allocation (1-lane 5 GHz vs. LS1020A's 4-lane 6 GHz), relocated DDR ball map, and unique CAN/UART ball assignments. PCB redesign is required when migrating from LS1020A/LS1021A to LS1022ASE7EKB.

What security features are implemented in LS1022ASE7EKB?

LS1022ASE7EKB includes the QorIQ SEC 5.5 hardware security engine supporting AES-128/256, SHA-1/256, RSA-2048, and true random number generation. It enables secure boot with immutable ROM-based bootloader, TrustZone-assisted secure world partitioning, and tamper-resistant fuse-based key storage. These features are documented in the LS1022A Security Reference Manual Rev.2.

What is the thermal design power (TDP) rating for LS1022ASE7EKB?

The LS1022ASE7EKB has a typical system-level power consumption of ≤1.9 W at 1.0 GHz operation and 100°C junction temperature, as specified in the LS1022A Data Sheet Rev.5 Table 3. This sub-2 W rating enables fanless enclosure designs and compatibility with Power over Ethernet (PoE) Class 4 power budgets.
