Product details
Overview
T2081NXN7PTB from NXP is a 28 nm QorIQ communications processor featuring four dual-threaded 64-bit e6500 Power Architecture® cores, 2 MB shared L2 cache, and up to 1.8 GHz operation. It integrates DPAA for packet parsing/classification (FMAN), queue management (QMAN), buffer management (BMAN), and hardware crypto acceleration (SEC) at up to 10 Gb/s. Designed for mid-range control/data plane applications, it serves in enterprise switches, LTE base station control cards, and industrial SBCs.
For engineers reviewing the T2081NXN7PTB datasheet, T2081NXN7PTB pinout, T2081NXN7PTB application, or T2081NXN7PTB equivalent, key selection criteria include its 780-pin 23×23 mm BGA package, 1x PCIe Gen3 + 3x PCIe Gen2 interface support, 7x 1 Gb/s MACs (SGMII), absence of SATA and SRIO, and pin compatibility with T1042 for board reuse in scalable product families.
Technical Context
The T2081NXN7PTB implements a hierarchical CoreNet interconnect fabric enabling coherent and non-coherent transactions with bandwidth allocation across endpoints. Its DPAA infrastructure includes FMAN for header parsing and classification at up to 24 Gb/s, QMAN supporting 224 queues with multi-level scheduling, and BMAN managing 64 buffer pools.
It supports hardware-assisted virtualization via hypervisor privilege level, logical-to-real address translation, PAMU v2 I/O MMU with paging, and vMPIC/vDMA for guest-isolated interrupt and DMA handling. The processor lacks RMAN and SATA controllers present in T2080, reflecting its streamlined I/O configuration for cost- and space-constrained control-plane deployments.

FAQ
What is the maximum DDR3/3L speed supported by T2081NXN7PTB?
T2081NXN7PTB supports DDR3/3L memory speeds up to 2133 MT/s using its 64-bit wide controller with 72-bit ECC. This enables high-bandwidth access for real-time packet buffering and OS execution while maintaining data integrity through error correction - essential for carrier-grade reliability in T2081NXN7PTB-based systems.
Does T2081NXN7PTB support hardware virtualization?
Yes, T2081NXN7PTB includes full hardware-assisted virtualization: hypervisor privilege level, logical-to-real address translation, PAMU v2 I/O MMU with paging, vMPIC, and vDMA. These features allow safe, low-overhead partitioning of control and data plane workloads - a core capability confirmed in the official T2080FS Rev 2 documentation applicable to T2081NXN7PTB.
Is T2081NXN7PTB pin-compatible with any other NXP processors?
Yes, T2081NXN7PTB is explicitly pin-compatible with the quad-core T1042 processor. This mechanical and electrical compatibility allows customers to reuse the same PCB layout across both devices - enabling scalable product families where T2081NXN7PTB serves as a performance upgrade without redesigning the board.
What Ethernet interfaces does T2081NXN7PTB provide?
T2081NXN7PTB provides seven 1 Gb/s SGMII MACs and two 10 Gb/s XFI/KR MACs - with no support for HiGig, XAUI, or RGMII. This configuration targets control-plane–centric applications needing high-density Gigabit connectivity and selective 10G uplinks, as specified in the T2080FS Rev 2 datasheet for T2081NXN7PTB.
Does T2081NXN7PTB include SATA or Serial RapidIO interfaces?
No, T2081NXN7PTB omits both SATA 2.0 controllers and Serial RapidIO ports - unlike the T2080NXN7PTB. This reflects its targeted role in compact, control-plane–focused designs where local storage and chip-to-chip interconnect are not required, as confirmed in the T2080FS Rev 2 feature comparison table.
