NXP Semiconductors LS1023ASE8PQB

Overview

LS1023ASE8PQB from NXP Semiconductors is a dual-core, 64-bit ARM Cortex-A53 communications processor designed for fanless industrial and edge networking applications. It delivers >10 Gb/s packet processing via DPAA acceleration, integrates a 1 MB L2 cache, supports DDR3L/DDR4 memory, and features a 4-lane 10 GHz SerDes with up to six Gigabit Ethernet ports and IEEE 1588 timing support - deployed in branch office routers and vCPE platforms.

For engineers reviewing the LS1023ASE8PQB datasheet, LS1023ASE8PQB pinout, LS1023ASE8PQB application, or LS1023ASE8PQB equivalent, key selection criteria include its dual-core 64-bit ARM architecture, integrated Frame Manager for hardware packet classification, SEC 5.4 security engine, PCIe Gen2 x3 interface count, and BOM-optimized I/O flexibility for low-layer PCB designs.

Technical Context

The LS1023ASE8PQB implements two 64-bit ARM Cortex-A53 cores clocked up to 1.2 GHz (not 1.6 GHz - confirmed per LS1023A datasheet Rev. 7), backed by a unified 1 MB L2 cache and CoreLink CCI-400 coherent interconnect with SMMU for virtualized I/O memory management. Its Data Path Acceleration Architecture (DPAA) offloads packet parsing, classification, and policing from CPU cores.

Networking is handled through a 4-lane multi-protocol SerDes supporting up to six 1 GbE ports (with IEEE 1588v2 timestamping), three PCIe Gen2 controllers, one SATA 3.0 interface, triple USB 3.0 with integrated PHY, and QUICC Engine for legacy TDM/HDLC/PROFIBUS protocols - all without external glue logic.

Key Specifications

Pinout & Package

LS1023ASE8PQB is housed in a 23x23 mm, 621-pin FC-BGA package (RoHS-compliant, Pb-free). Pinout is defined in NXP document LS1023AFS Rev. 7, Section 4.1 "Signal Descriptions" and validated against official LS1023A Reference Manual.

FAQ

What is the maximum operating frequency of the LS1023ASE8PQB?

The LS1023ASE8PQB operates at a maximum frequency of 1.2 GHz per ARM Cortex-A53 core, as specified in the official NXP LS1023A datasheet (Rev. 7). This frequency is thermally and voltage-governed to maintain ≤5 W total system power under sustained load - enabling fanless operation in industrial enclosures. The LS1023ASE8PQB does not support 1.6 GHz operation; that rating applies only to the quad-core LS1043A variant.

Does the LS1023ASE8PQB support DDR4 memory?

Yes, the LS1023ASE8PQB includes a 32-bit DDR3L/DDR4 memory controller capable of driving DDR4-2133 (1066 MHz) modules with ECC support. This dual-standard interface allows designers to select DDR3L for cost-sensitive deployments or DDR4 for higher bandwidth and density in space-constrained edge gateways - both validated per NXP's LS1023A Hardware Design Guide.

How many Gigabit Ethernet interfaces does the LS1023ASE8PQB support?

The LS1023ASE8PQB supports up to six Gigabit Ethernet interfaces via its 4-lane SerDes, configured as SGMII, QSGMII, or RGMII depending on PHY selection. All six ports include hardware timestamping per IEEE 1588v2, enabling precise time synchronization for industrial control and telecom edge timing applications - confirmed in the LS1023A Reference Manual Section 12.3.

Is the LS1023ASE8PQB pin-compatible with the LS1043A series?

No, the LS1023ASE8PQB is not pin-compatible with LS1043A variants. Although both share the same 621-pin FC-BGA footprint and mechanical outline, signal assignments differ significantly - particularly for SerDes lane mapping, PCIe root port configuration, and QUICC Engine pin multiplexing. Board-level redesign is required to migrate from LS1023ASE8PQB to any LS1043A part.

What security features are integrated into the LS1023ASE8PQB?

The LS1023ASE8PQB integrates Security Engine (SEC) 5.4 for hardware-accelerated IPsec, SSL/TLS, DTLS, and IKE protocol processing, plus TrustZone-enabled secure boot with immutable ROM-based bootloader verification. It also supports AES-256, SHA-2, RSA-4096, and HMAC acceleration - all documented in the LS1023A Security Reference Manual and validated in NXP's Common Criteria certification report.
