Product details
Overview
LS1023ASN7MQB 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 a 4-lane 10 GHz SerDes with up to six Gigabit Ethernet ports including IEEE 1588 support.
For engineers reviewing the LS1023ASN7MQB datasheet, LS1023ASN7MQB pinout, LS1023ASN7MQB application, or LS1023ASN7MQB equivalent, key selection criteria include dual-core 64-bit ARM performance per watt, integrated Frame Manager for hardware packet parsing/classification, SEC 5.4 for IPsec acceleration, PCIe Gen 2 ×3, USB 3.0 ×3, and QUICC Engine support for legacy TDM/HDLC/PROFIBUS protocols.
Technical Context
The LS1023ASN7MQB implements two 64-bit ARM Cortex-A53 cores clocked at 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 to offload packet classification, distribution, policing, and IP reassembly from CPU cores.
Networking is enabled through a 4-lane multi-protocol SerDes supporting up to six 1 GbE interfaces (with IEEE 1588 v2), three PCIe Gen 2 lanes, one SATA 3.0 port, and triple USB 3.0 controllers with integrated PHY. Security acceleration is handled by SEC 5.4 supporting IPsec, SSL/TLS, DTLS, IKE, and XOR RAID 5 operations.
