Product details
Overview
T2081NSE8MQB from NXP is a 28 nm QorIQ communications processor featuring four dual-threaded 64-bit e6500 Power Architecture® cores running at up to 1.8 GHz, integrated DPAA for packet processing up to 24 Gb/s, 2 MB shared L2 cache, and 64-bit DDR3/3L memory controller supporting 2133 MT/s. It serves as a control and mixed-plane processor in enterprise switches, wireless infrastructure control cards, and industrial SBCs.
For engineers reviewing the T2081NSE8MQB datasheet, T2081NSE8MQB pinout, T2081NSE8MQB application, or T2081NSE8MQB equivalent, key selection criteria include its 780-pin 23×23 mm package, PCIe Gen3+Gen2 configuration (1× Gen3 + 3× Gen2), support for up to seven 1 Gb/s MACs and two 10 Gb/s XFI/KR MACs, hardware virtualization with hypervisor privilege level, and SEC cryptography acceleration up to 10 Gb/s.
Technical Context
The T2081NSE8MQB implements a hierarchical CoreNet interconnect fabric enabling coherent and non-coherent transactions with bandwidth allocation across endpoints, and integrates a 512 KB platform cache with prefetch engine. Its DPAA subsystem includes FMAN for header parsing/classification, QMAN for multi-level queue scheduling across 224 queues, and BMAN for buffer pool management across 64 pools.
It supports hybrid 32/64-bit execution mode, state-retention power gating, and hardware-assisted virtualization including vMPIC, vDMA, PAMU v2 I/O MMU, and DPAA-level Ethernet MAC and accelerator virtualization. Unlike the T2080, it omits SATA, SRIO, RMAN, and Aurora interfaces, and reduces SerDes lanes from 16 to 8 and PCIe controllers from 4 to 4 (1 Gen3 + 3 Gen2).

FAQ
What is the maximum operating frequency of the T2081NSE8MQB?
The T2081NSE8MQB operates at up to 1.8 GHz across all four dual-threaded e6500 cores. This frequency is guaranteed under industrial temperature conditions (−40°C to +105°C) with appropriate thermal management and voltage regulation per NXP's recommended power delivery network. The T2081NSE8MQB achieves this while maintaining a short seven-stage pipeline optimized for control plane branch predictability.
Does the T2081NSE8MQB support hardware virtualization?
Yes, the T2081NSE8MQB supports comprehensive hardware virtualization including a dedicated hypervisor privilege level, logical-to-real address translation offload, vMPIC for virtualized interrupt handling, vDMA for user-level direct memory access, and PAMU v2 for I/O memory management. These features enable secure, high-performance partitioning of Linux and RTOS workloads on a single T2081NSE8MQB die.
How many Ethernet MAC interfaces does the T2081NSE8MQB support?
The T2081NSE8MQB supports up to seven 1 Gb/s MACs (via SGMII) and two 10 Gb/s MACs (via XFI/KR). These interfaces are multiplexed over the 8-lane SerDes and do not require external retimers. The T2081NSE8MQB does not support HiGig, XAUI, or 2.5 Gb/s SGMII variants present in the T2080.
Is the T2081NSE8MQB pin-compatible with any other NXP processors?
Yes, the T2081NSE8MQB is pin-compatible with the quad-core T1042 processor. This compatibility allows customers to reuse existing PCB layouts and migrate from T1042-based designs to higher-performance T2081NSE8MQB implementations without hardware revision-provided power delivery and thermal design accommodate the increased frequency and DPAA workload.
What accelerators are integrated into the T2081NSE8MQB's DPAA?
The T2081NSE8MQB integrates DPAA accelerators including FMAN for packet parsing and classification, QMAN for hierarchical queue scheduling across 224 queues, BMAN for buffer pool management across 64 pools, SEC for cryptography (AES/SHA/RSA) up to 10 Gb/s, and DCE for compression/decompression up to 17.5 Gb/s. PME pattern matching acceleration is not included in the T2081NSE8MQB.
