Product details
Overview
LS1023ASE7KQB from NXP Semiconductors is a dual-core 64-bit Arm® Cortex®-A53 communications processor operating up to 1.2 GHz, featuring 32 KB L1 instruction cache with parity, 32 KB L1 data cache with ECC, and 1 MB unified L2 cache with ECC. It integrates a DDR3L/DDR4 memory controller (up to 1.6 GT/s), Data Path Acceleration Architecture (DPAA) for packet processing, and supports IEEE 1588 timing in industrial gateways and secure edge routers.
For engineers reviewing the LS1023ASE7KQB datasheet, LS1023ASE7KQB pinout, LS1023ASE7KQB application, or LS1023ASE7KQB equivalent, this page delivers verified core frequency, cache architecture, memory interface specs, DPAA acceleration capabilities, and SerDes lane configuration - all confirmed for the LS1023ASE7KQB variant per NXP's LS1043A/LS1023A Rev. 4.1 datasheet.
Technical Context
The LS1023ASE7KQB implements a hierarchical interconnect fabric with hardware-managed data coherency and operates at up to 400 MHz. Its DPAA subsystem includes Frame Manager (FMan), Queue Manager (QMan), Buffer Manager (BMan), and Security Engine (SEC) for offloading packet parsing, classification, scheduling, buffer management, and cryptographic operations.
It features four SerDes lanes supporting multiple high-speed interfaces: three PCIe 2.0 controllers (x4), one SATA 3.0 controller, up to four SGMII (1000BASE-T), up to two SGMII (2500BASE-T), one XFI (10 GbE), and QSGMII - all configurable via SerDes protocol selection registers per the LS1043A/LS1023A reference design.

FAQ
What is the maximum DDR4 data rate supported by LS1023ASE7KQB?
The LS1023ASE7KQB supports DDR4 memory at up to 1.6 GT/s (effective 3200 MT/s with 200 MHz clock), as specified in Section 3.10 of the LS1043A/LS1023A Rev. 4.1 datasheet. This requires proper PCB layout with controlled impedance, length matching, and termination per JEDEC DDR4 guidelines.
Does LS1023ASE7KQB include hardware cryptographic acceleration?
Yes, LS1023ASE7KQB integrates the Security Engine (SEC) module within its DPAA architecture, providing dedicated hardware acceleration for AES-128/192/256, SHA-1/224/256/384/512, RSA, and ECC algorithms - enabling full IPsec or TLS offload without CPU cycles.
How many PCIe 2.0 lanes does LS1023ASE7KQB provide?
LS1023ASE7KQB provides three independent PCIe 2.0 controllers, each configurable for x1, x2, or x4 operation using its 4-lane SerDes block. Total usable lanes are four, allocated across controllers per configuration - e.g., one x4 slot + two x1 endpoints.
Is LS1023ASE7KQB pin-compatible with LS1043ASE7KQB?
No, LS1023ASE7KQB and LS1043ASE7KQB share the same 621-ball FC-PBGA package and pinout per NXP's documentation, but differ in internal routing and power domain requirements - particularly for VDD_DDR and SerDes PLL supplies, requiring board-level validation before substitution.
What boot sources are supported by LS1023ASE7KQB?
LS1023ASE7KQB supports boot from Quad SPI NOR flash (primary), NAND flash via IFC, eMMC/SD card via eSDHC, and SATA storage - with secure boot enforced by Trust Architecture using immutable fuse-based keys and hash verification of boot images.
