NXP Semiconductors LX2080CA72232B

Overview

LX2080CA72232B from NXP Semiconductors is an 8-core Arm Cortex-A72 network processor with 2.2 GHz core frequency, 8 MB L2 cache, dual 72-bit DDR4 controllers (3.2 GT/s, ECC), and DPAA2 datapath acceleration delivering 50 Gbps crypto and 100 Gbps compression throughput - deployed in carrier-grade edge routers and 5G small cell gateways.

For engineers reviewing the LX2080CA72232B datasheet, LX2080CA72232B pinout, LX2080CA72232B application, or LX2080CA72232B equivalent, key selection criteria include DDR4 ECC memory interface compliance, SerDes lane allocation for 25G/100G Ethernet, PCIe Gen3 scalability, hardware virtualization support (Arm MMU-500), and CAN-FD peripheral integration for automotive gateway use cases.

Technical Context

The LX2080CA72232B implements a cache-coherent interconnect fabric operating up to 1500 MHz with 8 MB Level 3 cache and On-Chip Memory (OCM) mode. Its Datapath Acceleration Architecture 2.0 (DPAA2) integrates WRIOP for packet parsing/classification, SEC for cryptography, DCE for compression/decompression, QDMA, and 2 MB Packet Express Buffer.

It supports 24 SerDes lanes configurable up to 25 Gbps per lane, two PCIe Gen3 x8 controllers with SR-IOV, four PCIe Gen3 x4 controllers, and up to 18 Ethernet MACs with IEEE 1588 timestamping, CAUI-4 (100G), 50GAUI-2 (50G), and USXGMII interfaces - all managed via Arm GIC-500 global interrupt controller and QorIQ Trust Architecture 3.0 with 256 KB secure on-chip RAM.

FAQ

What is the maximum DDR4 data rate supported by LX2080CA72232B?

The LX2080CA72232B supports DDR4 SDRAM at up to 3.2 GT/s with full ECC across both 72-bit channels. This translates to 25.6 GB/s aggregate memory bandwidth, validated under JEDEC JESD79-4 specifications with 1600 MHz clock frequency and appropriate signal integrity design.

Does LX2080CA72232B support PCIe Gen4?

No, LX2080CA72232B supports PCIe Gen3 only - with two x8 controllers and four x4 controllers. It does not implement PCIe Gen4 PHY or link layer logic; Gen4 capability is absent from the SerDes specification and electrical timing tables in the official data sheet Rev. 3 (09/2021).

How many CAN-FD interfaces does LX2080CA72232B integrate?

The LX2080CA72232B integrates two Controller Area Network (CAN) modules with Flexible Data Rate (CAN-FD) support, each capable of 5 Mbps operation. Both modules are accessible via dedicated CAN pins (CAN1_TX/CAN1_RX and CAN2_TX/CAN2_RX) and support ISO 11898-1:2015 compliance.

Is LX2080CA72232B pin-compatible with LX2160A?

Yes, LX2080CA72232B shares the same FC-PBGA 1517-ball package and pinout as LX2160A and LX2120A. Device differentiation is achieved solely through TEST_SEL_B and cfg_svr[0:1] strap pins per Table 1 in the data sheet - enabling single PCB design across all three variants.

What security features are implemented in LX2080CA72232B?

LX2080CA72232B implements QorIQ Platform Trust Architecture 3.0, including 256 KB on-chip secure RAM, ARM TrustZone, Secure Boot with immutable ROM code, hardware cryptographic accelerators (SEC), and tamper-detect circuitry with battery-backed monitoring - all documented in Sections 3.9 and 7 of the data sheet.
