Product details
Overview
LX2160XN72029B from NXP is a 16-core Arm Cortex-A72 network processor with 8 MB L3 cache, dual 72-bit DDR4-3200 controllers with ECC, and DPAA2 datapath acceleration delivering up to 50 Gbps crypto and 100 Gbps compression throughput. It integrates 24 SerDes lanes (up to 25 Gbps), 18 Ethernet MACs supporting 100G CAUI-4 and USXGMII, and hardware virtualization for telecom edge routing and secure SD-WAN appliances.
For engineers reviewing the LX2160XN72029B datasheet, LX2160XN72029B pinout, LX2160XN72029B application, or LX2160XN72029B equivalent, key selection criteria include DDR4 ECC memory controller bandwidth, SerDes lane count and protocol support (PCIe Gen3, SATA3, SFI/XFI), IEEE 1588 timestamping accuracy, and DPAA2 offload capability for packet classification and crypto acceleration.
Technical Context
The LX2160XN72029B implements a cache-coherent interconnect fabric operating at up to 1500 MHz, with 8 MB on-die L3 cache featuring ECC and OCM mode. Its 16 Cortex-A72 cores each deliver 2.2 GHz single-thread performance, 48 KB L1 instruction and 32 KB L1 data cache, and share 8 MB L2 cache across eight 2-core clusters.
DPAA2 architecture provides dedicated hardware blocks: WRIOP for packet parsing/classification/distribution, SEC for cryptographic acceleration (AES-GCM, SHA, RSA), DCE for lossless compression/decompression, QDMA for zero-copy transfers, and MC for management complex control. The device supports Arm MMU-500 for hardware virtualization and GIC-500 for global interrupt management.

The LX2160XN72029B integrates 18 fully independent Ethernet MACs, configurable for 1G/2.5G/10G/25G/40G/50G/100G speeds using SGMII, XFI, SFI, USXGMII, CAUI-4, or XLAUI physical layer interfaces. All MACs support IEEE 1588-2008 hardware timestamping with sub-50 ns resolution.
Is the LX2160XN72029B pin-compatible with the LX2160A?
Yes, the LX2160XN72029B is mechanically and electrically pin-compatible with the LX2160A. Both use the identical 1517-ball FC-PBGA package and share identical ball mapping, power sequencing, and signal integrity requirements per NXP's Rev. 3 datasheet. No PCB redesign is needed when migrating between these variants.
