Overview of LS1043ASN7PQB – IC MPU QORIQ 1.4GHZ 621FCPBGA
The LS1043ASN7PQB is an NXP QorIQ Layerscape microprocessor featuring a quad-core, 64-bit ARM Cortex-A53 CPU complex running at 1.4 GHz. It is designed for embedded networking and industrial infrastructure, delivering balanced compute performance, integrated networking I/O and security features for small-form-factor edge equipment.
Typical target uses include branch office routers, vCPE and edge appliances, multi-protocol IoT gateways, industrial PLC and control systems, and security appliances where integration, packet offload and robust I/O matter.
Key Features
- Core Quad ARM® Cortex®-A53 64-bit cores running at 1.4 GHz, providing multithreaded general-purpose processing for embedded networking tasks.
- Memory Supports DDR3L and DDR4 memory controllers for flexible system memory configurations.
- Networking & I/O Integrated multi-protocol SerDes and networking support including up to six Gigabit Ethernet interfaces (options including 1GbE and a 10GbE mix), three PCIe interfaces, one SATA 6Gbps port and three USB 3.0 ports plus PHY.
- Packet Offload & Acceleration Built to work with the QorIQ Data Path Acceleration Architecture (DPAA) and Frame Manager to enable hardware packet parsing, classification and policing—supporting up to 10 Gb/s of data-plane performance with reduced CPU overhead.
- Security Hardware security features include Secure Boot and ARM TrustZone®, together with an integrated security engine capable of in-line IPsec processing.
- System Integration CoreLink CCI-400 coherent interconnect with SMMU for hardware-enforced memory access controls useful for accelerators and peripherals operating on behalf of virtual machines.
- Package & Mounting Supplied in a 621-FCPBGA (21 × 21 mm) FCBGA package for surface-mount assembly.
- Operating Range & Compliance Qualified for consumer use with an operating temperature range of 0 °C to 105 °C and RoHS compliance.
Typical Applications
- Branch Office Routers Provides multi-core compute and DPAA packet offload for routing, packet classification and network services in compact router platforms.
- vCPE and Edge Appliances Supports virtualized and containerized network functions with SMMU memory controls and integrated accelerators for edge compute.
- Multi-protocol IoT Gateways Offers flexible I/O and SerDes-based interfaces for connecting diverse field networks and processing gateway data streams.
- Industrial PLC and Control Suitable for small-form-factor industrial controllers that require Ethernet connectivity, secure boot and robust operating temperature range.
- Security Appliances Integrated security engine and Frame Manager capabilities enable in-line IPsec and packet processing for security-oriented network devices.
Unique Advantages
- Highly Integrated Connectivity: Multiple Ethernet ports, PCIe, SATA and USB 3.0 interfaces reduce external controller count and simplify board-level design.
- Packet Processing Offload: DPAA and Frame Manager offload packet parsing, classification and policing to achieve up to 10 Gb/s data-plane performance with lower CPU load.
- Security-Ready Platform: Secure Boot, TrustZone and an integrated security engine support in-line IPsec to protect data and system integrity.
- Virtualization Support: CoreLink CCI-400 and SMMU provide hardware-enforced memory controls for accelerators and peripherals used by virtual machines.
- Design Flexibility: Support for DDR3L/DDR4 memory and a broad set of high-speed I/O options enables a range of small-form-factor, fanless designs.
