NXP Semiconductors T2081NSN7MQB

Overview

T2081NSN7MQB from NXP is a 28 nm QorIQ communications processor based on four dual-threaded 64-bit e6500 Power Architecture® cores, operating up to 1.8 GHz with 2 MB shared L2 cache, integrated DPAA for packet processing acceleration, and 780-pin 23 × 23 mm FC-BGA package. It serves as a pin-compatible upgrade from T1042 in mid-range control/data plane networking applications including enterprise switches and wireless infrastructure control cards.

For engineers reviewing the T2081NSN7MQB datasheet, T2081NSN7MQB pinout, T2081NSN7MQB application, or T2081NSN7MQB equivalent, key selection factors include its 1× PCIe Gen3 + 3× PCIe Gen2 interface count, absence of SATA and SRIO, reduced SerDes lanes (8 vs. 16), and support for up to two 10 Gb/s XFI/KR MACs - critical for compact, power-constrained edge routing and secure industrial SBC designs.

Technical Context

The T2081NSN7MQB implements hardware-assisted virtualization with hypervisor privilege level, logical-to-real address translation, and PAMU v2 I/O MMU for guest isolation - enabling safe co-location of control and data plane workloads. Its DPAA subsystem includes FMAN (packet parsing/classification), QMAN (224-queue scheduling), BMAN (64 buffer pools), SEC (10 Gb/s crypto), and DCE (17.5 Gb/s compression/decompression).

Unlike the T2080, the T2081NSN7MQB omits SATA 2.0 controllers, Serial RapidIO, Aurora interconnect, and one 10 Gb/s MAC lane group; it retains full CoreNet fabric coherence, 64-bit DDR3/3L memory controller (2133 MT/s), and 512 KB platform cache with prefetch - optimized for deterministic latency in real-time network control tasks.

FAQ

What is the maximum DDR3/3L speed supported by T2081NSN7MQB?

T2081NSN7MQB supports DDR3/3L memory speeds up to 2133 MT/s using its 64-bit interface with 72-bit ECC. This enables high-bandwidth, error-corrected memory subsystems essential for concurrent control plane and accelerated data path operations. The memory controller complies with JEDEC DDR3L standards and requires matched trace lengths and proper termination for stable operation at rated speed. T2081NSN7MQB achieves this performance while maintaining sub-15 W typical power draw in full-load configurations.

Does T2081NSN7MQB support hardware virtualization?

Yes, T2081NSN7MQB includes comprehensive hardware virtualization support: an extra hypervisor privilege level, logical-to-real address translation, vMPIC for virtualized interrupt handling, vDMA for user-level DMA, and PAMU v2 for I/O memory management. These features enable secure, low-overhead partitioning of Linux and RTOS workloads on T2081NSN7MQB - validated with NXP's hypervisor and KVM implementations. T2081NSN7MQB does not include tamper detection hardware, unlike the T2080 variant.

What Ethernet interfaces are available on T2081NSN7MQB?

T2081NSN7MQB provides up to seven 1 Gb/s SGMII MACs and two 10 Gb/s XFI/KR MACs, all multiplexed over its 8-lane SerDes. It lacks HiGig, XAUI, and 2.5 Gb/s SGMII support present in the T2080. The FMAN within T2081NSN7MQB handles full packet parsing, classification, and distribution for all enabled MACs - enabling line-rate forwarding in L2/L3 switching applications. No external PHY is required for SGMII links, but XFI/KR interfaces need compliant retimers or optical modules.

Is T2081NSN7MQB pin-compatible with any other NXP processors?

Yes, T2081NSN7MQB is explicitly pin-compatible with the quad-core T1042 processor, allowing direct board-level replacement and reuse of existing PCB layouts. This compatibility covers power, ground, SerDes, PCIe, USB, I²C, UART, and memory interface ballouts - though T2081NSN7MQB requires updated firmware and DDR training due to its e6500 core and enhanced memory controller. The 780-pin 23 × 23 mm FC-BGA footprint matches T1042's mechanical and thermal profile.

What differentiates T2081NSN7MQB from T2080NSN7MQB?

T2081NSN7MQB removes SATA 2.0 controllers, Serial RapidIO, Aurora interconnect, and one 10 Gb/s MAC lane group versus T2080NSN7MQB - resulting in 780 pins (vs. 896) and a 23 × 23 mm package (vs. 25 × 25 mm). It retains identical e6500 cores, DPAA, DDR controller, and virtualization features. T2081NSN7MQB targets space-constrained upgrades from T1042, while T2080NSN7MQB serves full-featured service cards needing storage, chip-to-chip interconnect, and higher port density.
