Overview

LS2048ASE711B from NXP Semiconductors is a quad-core Arm® Cortex®-A72 processor-based SoC with integrated DPAA2 data path acceleration, dual 64-bit DDR4 memory controllers (up to 2.1 GT/s), and 16 SerDes lanes supporting up to 10.3125 GHz-designed for high-throughput networking and embedded control in vehicle gateways and ADAS domain controllers.

For engineers reviewing the LS2048ASE711B datasheet, LS2048ASE711B pinout, LS2048ASE711B application, or LS2048ASE711B equivalent, key selection criteria include its AEC-Q100 Grade 3 qualification (105°C Tj), hardware virtualization support, TrustZone®-enabled security architecture, and PCIe 3.0 x8/x4/x2/x1 capability with SR-IOV on one controller.

Technical Context

The LS2048ASE711B implements four Cortex-A72 cores arranged in two clusters (2 cores/cluster, 1 MB shared L2 cache per cluster), operating up to 1.8 GHz under automotive thermal constraints. It integrates a hierarchical interconnect fabric linking CPU clusters, 1 MB platform cache with ECC, and DPAA2 accelerators including WRIOP, QBMan, SEC 5.2 (20 Gbps crypto), PME 2.0 (10 Gbps RegEx), and DCE 1.0 (20 Gbps compression).

Its I/O subsystem includes eight 10 Gbps Ethernet MACs, sixteen 1/2.5 Gbps Ethernet MACs, four PCIe 3.0 controllers (one with SR-IOV), two SATA 3.0, two USB 3.0 with PHY, eSDHC, QSPI, SPI, four I²C, two DUARTs, and an integrated flash controller-all managed via a secure service processor enabling pre-boot initialization and secure boot.

Key Specifications

Pinout & Package

FAQ

What is the maximum DDR4 data rate supported by LS2048ASE711B?

The LS2048ASE711B supports DDR4 memory up to 1.8 GT/s, aligned with its AEC-Q100 Grade 3 qualification (105°C Tj). This is a derated specification versus the 2.1 GT/s capability of non-automotive LS2044A/LS2084A variants, ensuring robust operation under sustained thermal stress in automotive environments. LS2048ASE711B maintains dual 64-bit DDR4 controllers with ECC and interleaving support at this rate.

Does LS2048ASE711B support PCIe 3.0 x8 configuration?

Yes, LS2048ASE711B supports PCIe 3.0 x8 on its PCIe3 controller, which also features SR-IOV capability. The remaining three PCIe controllers (PCIe1, PCIe2, PCIe4) support up to x4 width but do not implement SR-IOV. All controllers operate at Gen3 speed when platform clocking meets the ≥533 MHz requirement; below that threshold, PCIe3 remains x4-capable while others are limited to x2 at Gen3.

Is LS2048ASE711B pin-compatible with LS2044A or LS2084A?

Yes, LS2048ASE711B shares the identical 1292-ball FC-PBGA package and pinout with LS2044A and LS2084A. This enables mechanical and layout reuse across the QorIQ LS20xxA family. However, LS2048ASE711B is functionally a derivative of LS2044A (quad-core), with automotive qualification and thermal derating-not a distinct pinout variant.

What security features does LS2048ASE711B provide for automotive applications?

LS2048ASE711B integrates TrustZone®-enabled Armv8-A architecture, a dedicated service processor (SP) for pre-boot initialization and secure boot, hardware-enforced virtualization partitioning, and SEC 5.2 cryptography acceleration (20 Gbps). These features collectively support ISO 21434 threat analysis and ASIL-B/D software isolation requirements in automotive ECUs.

How many 10G Ethernet MACs does LS2048ASE711B support?

LS2048ASE711B supports up to eight 10 Gbps Ethernet MACs via its integrated SerDes lanes. These can be configured as standalone 10G interfaces or combined into higher-speed logical links (e.g., KR4 for backplane). The SoC also provides sixteen additional 1/2.5 Gbps Ethernet MACs, enabling flexible mixed-speed network topologies in vehicle gateways and domain controllers.
