Product details
Overview
LS2048ASN711B from NXP Semiconductors is a quad-core Arm® Cortex®-A72 SoC with two 64-bit DDR4 memory controllers (up to 2.1 GT/s), DPAA2 hardware acceleration, and 16 SerDes lanes supporting up to 10.3125 GHz - deployed in vehicle management servers, ADAS gateways, and secure industrial edge routers.
For engineers reviewing the LS2048ASN711B datasheet, LS2048ASN711B pinout, LS2048ASN711B application, or LS2048ASN711B equivalent, key selection criteria include DDR4 ECC support, automotive AEC-Q100 Grade 3 qualification (105°C Tj), DPAA2 crypto acceleration (20 Gbps SEC 5.2), and PCIe 3.0 x4/x2/x1 configuration flexibility across four controllers.
Technical Context
The LS2048ASN711B implements a hierarchical interconnect fabric linking four Cortex-A72 cores (two dual-core clusters, each with 1 MB shared L2 cache), 1 MB platform cache with ECC, and DPAA2 subsystem comprising WRIOP, QBMan, SEC 5.2, PME 2.0, and DCE 1.0 accelerators.
It integrates two DDR4 SDRAM controllers with interleaving and ECC, four PCIe 3.0 controllers (PCIe3 supports SR-IOV and x8/x4/x2/x1; others support x4/x2/x1 only), eight 10G/16×1–2.5G Ethernet MACs, and dual USB 3.0 PHYs - all under TrustZone®-enabled hardware virtualization and AEC-Q100 Grade 3 thermal compliance.

FAQ
What is the core architecture and maximum frequency of the LS2048ASN711B?
The LS2048ASN711B integrates four Arm Cortex-A72 64-bit processor cores arranged in two dual-core clusters, each sharing a 1 MB L2 cache. Its maximum operating frequency is 2.1 GHz under commercial conditions and 1.8 GHz when operating in AEC-Q100 Grade 3 automotive mode (105°C Tj). This frequency derating ensures timing margin and reliability in thermally demanding environments such as vehicle gateways.
Does the LS2048ASN711B support DDR4 memory with ECC and interleaving?
Yes, the LS2048ASN711B features two independent 64-bit DDR4 SDRAM memory controllers that fully support ECC protection, address/command parity, and memory interleaving across both channels. These controllers operate at up to 2.1 GT/s in standard mode and 1.8 GT/s in AEC-Q100 Grade 3 mode - enabling robust, high-bandwidth memory subsystems for safety-critical applications.
How many PCIe 3.0 controllers does the LS2048ASN711B include, and what are their capabilities?
The LS2048ASN711B includes four PCIe 3.0 controllers. PCIe3 supports x8/x4/x2/x1 widths and SR-IOV virtualization; PCIe1, PCIe2, and PCIe4 support only x4/x2/x1 and lack SR-IOV. At platform clock speeds below 533 MHz, PCIe1/2/4 are limited to x2 width for Gen3 operation, while PCIe3 maintains x4 - making PCIe3 the preferred link for high-throughput peripherals like NVMe SSDs or FPGA accelerators in LS2048ASN711B-based systems.
Is the LS2048ASN711B qualified for automotive applications?
Yes, the LS2048ASN711B is AEC-Q100 Grade 3 qualified for operation up to 105°C junction temperature. It includes automotive-specific features such as enhanced thermal monitoring, voltage/frequency derating profiles, and production test coverage aligned with automotive quality standards - making it suitable for under-hood vehicle management servers and ADAS gateway modules.
What hardware acceleration blocks are integrated into the LS2048ASN711B's DPAA2 subsystem?
The LS2048ASN711B's DPAA2 subsystem includes five key accelerators: WRIOP for packet parsing/classification/distribution; QBMan for hardware queue and buffer management; SEC 5.2 for crypto (20 Gbps AES-GCM/SHA); PME 2.0 for RegEx pattern matching (10 Gbps); and DCE 1.0 for compression/decompression (20 Gbps). All operate concurrently and are accessible via standardized Linux kernel drivers and NXP's SDK.
