NXP Semiconductors T1042NXN7MQB

Overview

T1042NXN7MQB from NXP Semiconductors is a quad-core 64-bit Power Architecture® communications processor featuring four e5500 cores up to 1.5 GHz, integrated Data Path Acceleration Architecture (DPAA), and a 5 Gb/s security engine (SEC 5.4); it targets fixed routers, enterprise switches, and industrial network appliances requiring deterministic packet processing and hardware virtualization support.

For engineers reviewing the T1042NXN7MQB datasheet, T1042NXN7MQB pinout, T1042NXN7MQB application, or T1042NXN7MQB equivalent, key selection criteria include DDR3L/4 memory controller speed (1600 MT/s), SerDes lane count (8×5 Gb/s), Ethernet MAC count (5×1 GbE), DPAA throughput (13 Gb/s classify/parse), and hypervisor-level virtualization support for partitioned control/data plane workloads.

Technical Context

The T1042NXN7MQB implements a hierarchical interconnect fabric with CoreNet coherency support, enabling cache-coherent communication among four e5500 cores, 256 KB shared L3 platform cache, and DPAA accelerators including Frame Manager (FMAN), Queue Manager (QMAN), and Buffer Manager (BMAN). It supports hybrid 32/64-bit execution mode for legacy software compatibility.

Its networking subsystem integrates five 1 GbE MACs with RGMII/SGMII interfaces, eight-lane SerDes supporting SGMII/QSGMII/PCIe/SATA, and dual DMA controllers - distinct from the T1040/T1020 which include an 8-port switch not present in the T1042NXN7MQB.

FAQ

What is the maximum DDR memory speed supported by the T1042NXN7MQB?

The T1042NXN7MQB supports DDR3L and DDR4 memory at up to 1600 MT/s with full ECC capability. This speed enables sustained bandwidth for DPAA buffer management and multi-core cache coherency. The memory controller is single-channel but optimized for low-latency access patterns typical in packet-forwarding workloads. T1042NXN7MQB implementations require careful PCB layout for signal integrity at this data rate.

Does the T1042NXN7MQB include an integrated Ethernet switch?

No, the T1042NXN7MQB does not include an integrated Ethernet switch. Unlike the T1040NXN7MQB, it provides five 1 GbE MACs only - requiring external PHYs and optionally an external switch IC. This design choice prioritizes flexibility in port configuration and reduces die area for applications where switch functionality is handled separately. T1042NXN7MQB retains full DPAA packet classification and QoS scheduling capabilities independent of switch presence.

Which virtualization software is validated for use with the T1042NXN7MQB?

The T1042NXN7MQB supports kernel-based virtual machine (KVM), NXP's own hypervisor, Linux containers, and commercial offerings from Green Hills Software and Enea. Its e5500 core includes a dedicated hypervisor privilege level (HV), and the PAMU (Peripheral Access Management Unit) enforces memory isolation between VMs. T1042NXN7MQB reference platforms ship with pre-integrated KVM and NXP hypervisor images for rapid evaluation.

How many SerDes lanes does the T1042NXN7MQB provide, and what protocols do they support?

The T1042NXN7MQB integrates eight SerDes lanes operating at up to 5 Gb/s each. These lanes are configurable as SGMII (for 1 GbE PHYs), QSGMII (for multi-port PHY aggregation), PCIe 2.0 (x1 or x2 links), or SATA 2.0 (up to two ports). Lane assignment is defined at boot via configuration fuses and cannot be dynamically reconfigured during runtime. T1042NXN7MQB's SerDes implementation complies with IEEE 802.3 and PCI-SIG specifications.

What distinguishes the T1042NXN7MQB from the T1022NXN7MQB in terms of processing capability?

The T1042NXN7MQB features four e5500 cores versus two in the T1022NXN7MQB, doubling raw compute capacity for control-plane tasks like routing protocol stacks and application-layer inspection. Both share identical DPAA, SEC 5.4, DDR, and SerDes specs. T1042NXN7MQB also includes dual four-channel DMA controllers - enabling higher concurrent peripheral bandwidth - whereas the T1022NXN7MQB has a single DMA block. T1042NXN7MQB targets higher-throughput, multi-service deployments.
