NXP Semiconductors LX2080CC72232B

Overview

LX2080CC72232B from NXP is an 8-core Arm Cortex-A72 network processor with 8 MB L2 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 18 Ethernet MACs supporting 1G–100G rates including USXGMII, CAUI-4, and 50GAUI-2, targeting high-throughput secure networking appliances.

For engineers reviewing the LX2080CC72232B datasheet, LX2080CC72232B pinout, LX2080CC72232B application, or LX2080CC72232B equivalent, key selection criteria include DDR4 ECC memory interface timing, SerDes lane configuration (24 lanes @ 25 Gbps), PCIe Gen3 controller count (five total), and hardware virtualization support via Arm MMU-500.

Technical Context

The LX2080CC72232B implements a cache-coherent interconnect fabric operating at up to 1500 MHz with 8 MB L3 cache and ECC-protected on-chip memory mode. Its Datapath Acceleration Architecture 2.0 (DPAA2) includes WRIOP for packet parsing/classification, SEC for cryptography, DCE for compression/decompression, and QDMA for zero-copy transfers.

It supports IEEE 1588 precision time protocol across all 18 Ethernet MACs, with physical layer interfaces spanning SGMII, XFI, SFI, 10GBase-KR, USXGMII, CAUI-4, 50GAUI-2, and XLAUI. Two CAN-FD modules, FlexSPI, eight I²C controllers, and Arm GIC-500 global interrupt management are integrated for heterogeneous system control.

FAQ

What is the maximum DDR4 data rate supported by the LX2080CC72232B?

The LX2080CC72232B supports DDR4-3200 (1600 MHz clock), delivering 51.2 GB/s aggregate bandwidth across its dual 72-bit interfaces. Each channel uses 64 data bits plus 8 ECC bits, with strict setup/hold timing enforced by on-die termination and programmable drive strength per DQ group.

Does the LX2080CC72232B support PCIe Gen4?

No, the LX2080CC72232B supports five PCIe Gen3 controllers only: one x8 and four x4 configurations. It does not implement PCIe Gen4 PHY or link training logic; Gen3 operation is confirmed in Section 3.23.4 of the official datasheet Rev. 3.

How many SerDes lanes can be allocated to SATA 3.0 interfaces?

The LX2080CC72232B dedicates four SerDes lanes to each of its four SATA 3.0 controllers, consuming 16 of the 24 total SerDes lanes. Remaining lanes are assigned to PCIe, Ethernet, or USXGMII as configured via the SerDes personality registers.

Is hardware virtualization implemented via ARM TrustZone or a separate IP block?

Hardware virtualization in the LX2080CC72232B is implemented using the Arm MMU-500 memory management unit, which provides stage-2 translation and VM isolation. TrustZone is used separately for secure world execution, while MMU-500 enforces partitioning between virtual machines in the normal world.

What is the function of the cfg_svr[0:1] pins on the LX2080CC72232B?

The cfg_svr[0:1] pins (XSPI1_A_CS0_B and XSPI1_A_CS1_B) configure device personality at reset: setting cfg_svr0=0 and cfg_svr1=1 selects the LX2080A variant. This matches Table 1 in the datasheet and determines core count, L2 cache size, and MAC count during boot.
