Product details
Overview
LS2084ASN7V17B from NXP Semiconductors is a high-performance 64-bit Arm Cortex-A72-based network processor with eight A72 cores (four dual-core clusters), 1 MB platform cache with ECC, dual 64-bit DDR4 memory controllers supporting up to 2.1 GT/s, and integrated DPAA2 acceleration for wire-rate packet processing, cryptography (20 Gbps), RegEx (10 Gbps), and compression (20 Gbps). It targets carrier-grade routers, telecom infrastructure, and ADAS gateway servers.
For engineers reviewing the LS2084ASN7V17B datasheet, LS2084ASN7V17B pinout, LS2084ASN7V17B application, or LS2084ASN7V17B equivalent, key selection criteria include DDR4 ECC support, SerDes lane count (16 lanes @ 10.3125 GHz), PCIe 3.0 configuration flexibility (including SR-IOV on PCIe3), automotive AEC-Q100 Grade 3 qualification, and DPAA2 hardware offload capability for real-time networking workloads.
Technical Context
The LS2084ASN7V17B implements a hierarchical interconnect fabric linking eight Cortex-A72 cores, dual DDR4 controllers, DPAA2 acceleration complex (WRIOP, QBMan, SEC 5.2, PME 2.0, DCE 1.0), qDMA engine, and multiple high-speed I/Os. Its cache coherency architecture supports L1/L2/Platform Cache hierarchy with ECC protection across all levels.
It integrates two independent 64-bit DDR4 SDRAM controllers with interleaving, ECC, and per-channel timing control - each supporting up to 2.1 GT/s data rates. The 16-lane SerDes supports configurable protocols including PCIe 3.0, SATA 3.0, USB 3.0, and 10G/2.5G Ethernet PHYs, with dedicated PLLs and impedance calibration for signal integrity.

FAQ
What is the maximum DDR4 data rate supported by LS2084ASN7V17B?
The LS2084ASN7V17B supports up to 2.1 GT/s per DDR4 channel under standard operating conditions. In AEC-Q100 Grade 3 mode (105°C Tj), the maximum DDR4 data rate is reduced to 1.8 GT/s to maintain signal integrity and timing margin across temperature extremes.
Does LS2084ASN7V17B support PCIe 3.0 x8 configuration?
Yes, LS2084ASN7V17B supports PCIe 3.0 x8 configuration exclusively on the PCIe3 controller, which also supports SR-IOV. The other three PCIe controllers (PCIe1, PCIe2, PCIe4) are limited to x4/x2/x1 widths and do not support SR-IOV.
Is LS2084ASN7V17B pin-compatible with LS2044ASN7V17B?
No, LS2084ASN7V17B and LS2044ASN7V17B share the same 1292-ball FC-PBGA package footprint but are not pin-compatible due to differences in SerDes lane allocation, DDR4 interface routing, and power delivery requirements - PCB redesign is required for substitution.
What cryptographic algorithms does the SEC 5.2 engine in LS2084ASN7V17B accelerate?
The SEC 5.2 engine in LS2084ASN7V17B accelerates AES-128/192/256 (ECB/CBC/CTR/GCM), SHA-1/SHA-224/SHA-256/SHA-384/SHA-512, RSA up to 4096-bit, ECC NIST P-256/P-384/P-521, and HMAC-SHA - delivering up to 20 Gbps aggregate throughput.
How is the LS2084ASN7V17B qualified for automotive applications?
LS2084ASN7V17B is AEC-Q100 Grade 3 qualified (105°C Tj), with validated operation across -40°C to +105°C ambient, enhanced ESD robustness (HBM ≥2 kV), and manufacturing process controls meeting automotive PPAP requirements - enabling deployment in vehicle domain gateways and ADAS control units.
