Product details
Overview
T2081NSN8MQB 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, and hardware virtualization support. It serves as a control/data plane processor in mid-range networking equipment including enterprise switches, LTE base station control cards, and industrial SBCs.
For engineers reviewing the T2081NSN8MQB datasheet, T2081NSN8MQB pinout, T2081NSN8MQB application, or T2081NSN8MQB equivalent, key selection considerations include its 780-pin 23×23 mm package, 1x PCIe Gen3 + 3x PCIe Gen2 interface count, 2×10 Gb/s XFI-capable MACs, absence of SATA and SRIO, and pin compatibility with T1042 for board reuse in scalable product families.
Technical Context
The T2081NSN8MQB implements a hierarchical CoreNet interconnect fabric supporting coherent and non-coherent transactions with bandwidth allocation, paired with a 64-bit DDR3/3L memory controller running up to 2133 MT/s (72-bit with ECC). Its DPAA infrastructure includes FMAN for packet parsing/classification at up to 24 Gb/s, QMAN for 224-queue scheduling, and BMAN for buffer pool management across 64 pools.
Hardware virtualization is enabled via hypervisor privilege level, logical-to-real address translation, PAMU v2 I/O MMU, and DPAA-level Ethernet MAC and accelerator virtualization. Unlike the T2080, the T2081 omits SATA 2.0, Serial RapidIO, RMAN, and one PCIe Gen3 controller - reflecting its targeted role as a cost-optimized, pin-compatible upgrade path from the quad-core T1042.
