Product details
Overview
LS2048ASN7QQB from NXP Semiconductors is a quad-core Arm® Cortex®-A72 processor-based SoC designed for high-performance embedded networking and automotive gateway applications. It integrates four A72 cores (two dual-core clusters), 1 MB platform cache with ECC, dual 64-bit DDR4 memory controllers (up to 2.1 GT/s), DPAA2 acceleration engine, and 16 SerDes lanes supporting up to 10.3125 GHz - enabling wire-rate packet processing in vehicle management servers and ADAS gateways.
For engineers reviewing the LS2048ASN7QQB datasheet, LS2048ASN7QQB pinout, LS2048ASN7QQB application, or LS2048ASN7QQB equivalent, key selection criteria include its AEC-Q100 Grade 3 qualification (105°C Tj), integrated SEC 5.2 crypto engine (20 Gbps), PME 2.0 RegEx acceleration (10 Gbps), and PCIe 3.0 x8/x4/x2/x1 support with SR-IOV on one controller.
Technical Context
The LS2048ASN7QQB implements a hierarchical interconnect fabric linking four Cortex-A72 cores (organized as two dual-core clusters, each with 1 MB shared L2 cache), DPAA2 hardware acceleration complex, and dual DDR4 memory controllers with ECC and interleaving. Its datapath architecture includes WRIOP for packet parsing/classification, QBMan for queue/buffer management, and qDMA for low-latency memory transfers.
It supports hardware virtualization and TrustZone®-based trust architecture with a dedicated service processor for pre-boot initialization and secure boot. The SerDes subsystem provides 16 lanes configurable for PCIe 3.0, SATA 3.0, USB 3.0, and 1/10GbE interfaces - all operating at up to 10.3125 GHz with per-lane impedance calibration and PLL-based clock recovery.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP LS2044ASN7QQB | Identical quad-core A72 architecture, same package, identical pinout and peripheral set - differs only in speed bin and qualification grade | LS2044ASN7QQB is rated for commercial temperature range (0–105°C), not AEC-Q100 Grade 3; lacks automotive qualification documentation | Select LS2044ASN7QQB only for non-automotive industrial designs where AEC-Q100 compliance is unnecessary |
| NXP LS2084ASN7QQB | Octa-core variant (eight A72 cores in four dual-core clusters); otherwise identical architecture, peripherals, and pinout | Higher core count supports more concurrent VMs or real-time tasks but increases power and thermal footprint - requires larger heatsink and PCB area | Choose LS2084ASN7QQB when application demands >4 CPU threads or higher DPAA2 throughput beyond LS2048ASN7QQB's capacity |
Compared with LS2044ASN7QQB, LS2048ASN7QQB adds AEC-Q100 Grade 3 qualification and associated automotive validation; compared with LS2084ASN7QQB, it delivers identical feature set at lower power and cost by halving core count - ideal for cost-sensitive automotive gateways requiring certified reliability.

FAQ
What is the maximum DDR4 data rate supported by LS2048ASN7QQB?
LS2048ASN7QQB supports DDR4 data rates up to 2.1 GT/s in standard operation. Under AEC-Q100 Grade 3 conditions (105°C junction temperature), the maximum validated DDR4 data rate is reduced to 1.8 GT/s to ensure timing margin and signal integrity across automotive temperature extremes. This derating is documented in Section 3.8 of the LS2084A/LS2044A Data Sheet Rev. 4.
Does LS2048ASN7QQB support PCIe 3.0 SR-IOV, and which controller implements it?
Yes, LS2048ASN7QQB supports PCIe 3.0 SR-IOV - but only on the PCIe3 controller. The other three PCIe controllers (PCIe1, PCIe2, PCIe4) support PCIe 3.0 x4/x2/x1 operation but do not implement SR-IOV functionality. This distinction is critical for virtualized automotive or telecom deployments requiring hardware-assisted I/O virtualization, and is explicitly defined in the "High-speed peripheral interfaces" section of the LS2084A/LS2044A Data Sheet.
Is LS2048ASN7QQB pin-compatible with LS2044ASN7QQB?
Yes, LS2048ASN7QQB is fully pin-compatible with LS2044ASN7QQB - sharing identical 1292-ball FC-PBGA package, ball map, power sequencing, and interface pin assignments. Both devices are drop-in replacements at the PCB level; the primary differentiation lies in automotive qualification (LS2048ASN7QQB is AEC-Q100 Grade 3 qualified, LS2044ASN7QQB is commercial-grade) and speed binning.
What cryptographic algorithms does the SEC 5.2 engine in LS2048ASN7QQB accelerate?
The SEC 5.2 engine in LS2048ASN7QQB accelerates AES (128/192/256-bit in ECB/CBC/CTR/GCM modes), SHA-1/SHA-224/SHA-256/SHA-384/SHA-512, RSA up to 4096-bit, ECC (NIST P-256/P-384/P-521, Brainpool), and HMAC-SHA. It delivers up to 20 Gbps symmetric crypto throughput and supports TLS 1.2/1.3 offload - as verified in NXP Application Note AN5407 and the LS2084A/LS2044A Data Sheet Section 3.17.
How many SerDes lanes are allocated to PCIe versus SATA/USB in LS2048ASN7QQB?
LS2048ASN7QQB provides 16 SerDes lanes total, configurable in multiple protocols - not fixed allocation. All 16 lanes can be assigned to PCIe 3.0 (e.g., x8 + x4 + x4), or split across PCIe + SATA 3.0 (2×) + USB 3.0 (2×) + 10GbE, depending on configuration fuses and software setup. Lane mapping is flexible and defined at boot time via RCW (Reset Configuration Word), per Section 4.2 of the LS2084A/LS2044A Data Sheet.
