NXP Semiconductors LS2084ASN711B

Overview

LS2084ASN711B from NXP Semiconductors is an 8-core Arm® Cortex®-A72 SoC with DPAA2 data path acceleration, dual 64-bit DDR4 memory controllers (up to 2.1 GT/s), 16 SerDes lanes (up to 10.3125 GHz), and integrated security engine (SEC 5.2) delivering up to 20 Gbps crypto throughput - deployed in vehicle management servers, ADAS gateways, and telecom infrastructure.

For engineers reviewing the LS2084ASN711B datasheet, LS2084ASN711B pinout, LS2084ASN711B application, or LS2084ASN711B equivalent, key selection considerations include DDR4 ECC support, PCIe 3.0 SR-IOV capability on one controller, automotive AEC-Q100 Grade 3 qualification (105°C Tj), and DPAA2 hardware offload for packet classification, queue management, and RegEx matching at line rate.

Technical Context

The LS2084ASN711B implements a hierarchical interconnect fabric linking eight Cortex-A72 cores (organized in four dual-core clusters, each with 1 MB shared L2 cache) to DPAA2 accelerators including WRIOP for wire-rate packet parsing, QBMan for hardware-managed queue scheduling, and SEC 5.2 for AES-GCM/SHA acceleration.

It integrates two independent DDR4 SDRAM controllers with ECC, interleaving, and 2.1 GT/s operation; four PCIe 3.0 controllers (one supporting x8/x4/x2/x1 + SR-IOV, three supporting x4/x2/x1 only); and dual 10 Gbps Ethernet MACs plus sixteen 1/2.5 Gbps MACs - all synchronized via a 1 MB platform cache with ECC protection.

Key Specifications

FAQ

What is the maximum DDR4 data rate supported by LS2084ASN711B?

The LS2084ASN711B supports up to 2.1 GT/s on both DDR4 memory controllers under standard operating conditions. In AEC-Q100 Grade 3 automotive mode (105°C Tj), the maximum DDR4 data rate is derated to 1.8 GT/s to ensure reliability across temperature extremes - verified in NXP DS Rev. 4 Section 3.8.

Does LS2084ASN711B support PCIe 3.0 SR-IOV, and on which controller?

Yes, LS2084ASN711B supports PCIe 3.0 SR-IOV exclusively on the PCIe3 controller, which is configurable for x8/x4/x2/x1 widths. The other three PCIe controllers (PCIe1, PCIe2, PCIe4) support only x4/x2/x1 and lack SR-IOV capability - confirmed in NXP DS Rev. 4 Section 1.1 and Table 3-14.

Is LS2084ASN711B qualified for automotive applications?

Yes, LS2084ASN711B is AEC-Q100 Grade 3 qualified for operation up to 105°C junction temperature. This includes derated specifications: 1.8 GHz max CPU frequency and 1.8 GT/s max DDR4 data rate - documented in NXP DS Rev. 4 Section 1 and Table 8-1 ordering information.

What DPAA2 acceleration functions are implemented in LS2084ASN711B?

LS2084ASN711B implements full DPAA2: WRIOP for packet parsing/classification/distribution; QBMan for hardware queue/buffer management; SEC 5.2 for crypto (20 Gbps AES-GCM/SHA); PME 2.0 for RegEx (10 Gbps); and DCE 1.0 for compression/decompression (20 Gbps) - all detailed in NXP DS Rev. 4 Section 1.1 Features.

What package type and ball count does LS2084ASN711B use?

LS2084ASN711B uses a 1292-ball Fine-Pitch Ceramic Ball Grid Array (FC-PBGA) package measuring 27 mm × 27 mm with 0.8 mm pitch and integrated thermal lid - specified in NXP DS Rev. 4 Section 6 and Figure 2 ball map diagram.
