Product details
Overview
LS1048ASN7Q1A from NXP is a 4-core ARM Cortex-A53 64-bit communications processor operating at up to 1.6 GHz, featuring DPAA2 data path acceleration, dual 10 GbE + eight 1 GbE interfaces, and integrated SEC crypto engine. It serves as the control and data plane processor in virtual CPE, wireless access point control, and industrial edge gateways requiring deterministic packet processing and Linux-based real-time orchestration.
For engineers reviewing the LS1048ASN7Q1A datasheet, LS1048ASN7Q1A pinout, LS1048ASN7Q1A application, or LS1048ASN7Q1A equivalent, key selection criteria include DDR4 ECC memory controller support (2.1 GT/s), PCIe 3.0 x4/x2/3×1 configuration flexibility, SR-IOV readiness for NFV workloads, and hardware-accelerated vSwitch offload across eight 1 GbE ports.
Technical Context
The LS1048ASN7Q1A implements a hierarchical coherency fabric (CoreLink CCI-400) linking four Cortex-A53 cores (two clusters, each with 1 MB L2 cache) and DPAA2 subsystems including AIOP, SEC, and Queue/Buffer Manager. It supports hardware-enforced virtualization via TrustZone and SMMUs for secure partitioning of network functions.
Its networking stack integrates wire-rate I/O processing with HW parsing, classification, policing, and MACSec on up to four 1 GbE ports. The 4-lane 10 GHz SerDes supports flexible interface mapping to 1/10GbE (XFI/KR, QSGMII), PCIe 3.0, SATA 3.0, and USB 3.0 PHYs - all configurable without external glue logic.
