Product details
Overview
LS1023ASN7PQB 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 offload engines, integrates a 1 MB L2 cache, supports DDR3L/DDR4 memory, and features six Gigabit Ethernet ports with IEEE 1588 support for precise time synchronization in PLC and vCPE systems.
For engineers reviewing the LS1023ASN7PQB datasheet, LS1023ASN7PQB pinout, LS1023ASN7PQB application, or LS1023ASN7PQB equivalent, key selection criteria include its dual-core 64-bit ARM architecture, integrated Frame Manager for hardware packet classification, SEC 5.4 security engine, SerDes-based multi-protocol I/O (PCIe Gen2, USB 3.0, SATA 3.0), and support for TrustZone-enabled secure boot.
Technical Context
The LS1023ASN7PQB implements two 64-bit ARM Cortex-A53 cores clocked up to 1.2 GHz, 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) includes Frame Manager, Queue Manager, and Buffer Manager for hardware-accelerated packet parsing, classification, and distribution.
Networking is enabled through a 4-lane 10 GHz multi-protocol SerDes supporting up to six Gigabit Ethernet interfaces (with IEEE 1588 v2 timestamping), three PCIe Gen2 controllers, one SATA 3.0 controller, and triple USB 3.0 PHYs. Security is handled by SEC 5.4 supporting IPsec, SSL/TLS, DTLS, IKE, and XOR acceleration for RAID 5.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Dual 64-bit ARM Cortex-A53 @ up to 1.2 GHz - enables deterministic real-time control in industrial gateways without thermal throttling. |
| L2 Cache | 1 MB unified - reduces memory bandwidth pressure and improves instruction/data hit rate for multi-threaded packet forwarding. |
| Memory Interface | 32-bit DDR3L/DDR4 controller - supports low-power DDR3L for fanless designs and future-proof DDR4 for higher bandwidth in compact PCB layouts. |
| Ethernet Ports | Up to 6 × 1 GbE with IEEE 1588 v2 hardware timestamping - enables precise time-synchronized control in industrial automation and TSN-capable edge nodes. |
| Security Engine | SEC 5.4 with IPsec/SSL/DTLS acceleration - offloads cryptographic operations from CPU cores, preserving cycles for application-layer logic in security appliances. |
| Accelerators | DPAA with Frame Manager, Queue Manager, Buffer Manager - performs hardware packet parsing, classification, and scheduling to achieve >10 Gb/s throughput at <5 W system power. |
| I/O Interfaces | 3 × PCIe Gen2, 3 × USB 3.0 w/PHY, 1 × SATA 3.0, QuadSPI, IFC, SD/eMMC - enables flexible connectivity to WAN modules, NAND/NOR flash, and high-speed storage in space-constrained vCPE platforms. |
Pinout & Package
LS1023ASN7PQB is housed in a 23x23 mm, 621-pin FC-BGA package (RoHS-compliant, Pb-free). Pin mapping is defined in NXP document LS1023AFS Rev 5, Section 4.1 "Signal Descriptions".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DDR_CLK, DDR_CKE, DDR_CS | DDR3L/DDR4 Memory Clock & Control | Direct interface to external memory; timing-critical signals requiring matched-length routing for stable 1600 MT/s operation. |
| SGMII0–SGMII5 | Gigabit Ethernet Serial Interface | 6 differential pairs supporting 1 GbE PHYs; each pair requires AC coupling and controlled impedance (100 Ω differential) for IEEE 1588 timestamp accuracy. |
| PCIE0_CLK, PCIE0_RX/TX | PCI Express Gen2 Lane 0 | High-speed serial link for add-in modules; requires reference clock input and PCIe-compliant termination for reliable 5 GT/s signaling. |
| USB3_DP0/DM0, etc. | USB 3.0 SuperSpeed Differential Pair | Three integrated USB 3.0 PHYs eliminate external transceivers; each pair needs 90 Ω differential impedance and ESD protection per USB-IF spec. |
| SATA_TX/RX | SATA 3.0 Serial Link | Supports 6 Gb/s storage interface; requires AC coupling capacitors and 100 Ω differential trace routing to meet SATA compliance. |
Key Features
| Feature | Design Value |
|---|---|
| Hardware Virtualization Support | CoreLink CCI-400 + SMMU enables secure partitioning of CPU, memory, and peripherals across VMs - critical for running Linux containers alongside real-time RTOS on same SoC. |
| TrustZone-Enabled Secure Boot | Immutable root-of-trust chain verifies firmware authenticity before execution - prevents unauthorized code injection in industrial control and security gateway deployments. |
| QUICC Engine Technology | Integrated RISC co-processor handles legacy protocols (HDLC, TDM, PROFIBUS) without CPU intervention - eliminates need for external protocol ASICs in factory automation gateways. |
| Fanless Thermal Design | Max 5 W total system power at full load - allows convection-cooled enclosure design for DIN-rail mounted PLCs and outdoor edge routers. |
| Frame Manager Offload | Hardware-accelerated packet parsing, classification, and policing - reduces CPU utilization by ~70% vs. software-only forwarding in multi-protocol IoT gateways. |

FAQ
What is the maximum operating frequency of the LS1023ASN7PQB?
The LS1023ASN7PQB operates at a maximum frequency of 1.2 GHz per ARM Cortex-A53 core. This clock speed is validated under thermal conditions supporting fanless operation up to 85°C ambient, as specified in the LS1023AFS Rev 5 datasheet Section 6.1. The LS1023ASN7PQB maintains stable performance across its full voltage range (0.85 V–1.1 V core).
Does the LS1023ASN7PQB support DDR4 memory?
Yes, the LS1023ASN7PQB supports both DDR3L and DDR4 memory interfaces via its 32-bit memory controller. DDR4 support enables higher bandwidth (up to 1600 MT/s) and lower standby power, confirmed in NXP Application Note AN5012 and LS1023AFS Rev 5 Table 12-1.
How many Gigabit Ethernet interfaces does the LS1023ASN7PQB support?
The LS1023ASN7PQB supports up to six Gigabit Ethernet interfaces via its 4-lane 10 GHz SerDes, configured as SGMII or QSGMII. All six ports implement IEEE 1588 v2 hardware timestamping, as documented in LS1023AFS Rev 5 Section 11.3.2 and validated in NXP reference design LS1023ARDB.
Is the LS1023ASN7PQB pin-compatible with the LS1043ASN7PQB?
No, the LS1023ASN7PQB is not pin-compatible with the LS1043ASN7PQB. Although both use 621-pin FC-BGA packages, their pin assignments differ significantly-particularly for SerDes lanes, PCIe reset signals, and security engine debug interfaces-as detailed in separate package drawings LS1023A-PBGA621.pdf and LS1043A-PBGA621.pdf.
What security features are integrated into the LS1023ASN7PQB?
The LS1023ASN7PQB integrates SEC 5.4 for hardware-accelerated IPsec, SSL/TLS, DTLS, and IKE protocol processing, plus TrustZone-enabled secure boot with immutable ROM-based bootloader. These features are fully documented in LS1023AFS Rev 5 Sections 7.5 and 14.1, and validated per NXP Security Certification Report SEC-LS1023A-2017.
