Product details
Overview
T2081NSE8P1B from NXP Semiconductors 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 acceleration, and a 2 MB shared L2 cache. It delivers up to 7.2 GHz aggregate core performance with hardware virtualization support, targeting control plane and mixed data/control applications in enterprise switches and wireless infrastructure.
For engineers reviewing the T2081NSE8P1B datasheet, T2081NSE8P1B pinout, T2081NSE8P1B application, or T2081NSE8P1B equivalent, key selection criteria include its 780-pin 23 × 23 mm package, 1× PCIe Gen3 + 3× PCIe Gen2 interface count, 2× 10 Gb/s XFI-capable MACs, and pin compatibility with the T1042 for board reuse in scalable product families.
Technical Context
The T2081NSE8P1B implements a hierarchical CoreNet interconnect fabric supporting coherent and non-coherent transactions with bandwidth allocation, paired with a 64-bit DDR3/3L memory controller operating up to 2133 MT/s (72-bit with ECC). Its DPAA subsystem 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-assisted virtualization is enabled via hypervisor privilege level, logical-to-real address translation offload, PAMU v2 I/O MMU, and vMPIC/vDMA support. Security features include secure boot and tamper detection-though tamper detection is confirmed only on T2080 per official documentation and is excluded for T2081NSE8P1B.

FAQ
What is the maximum DDR3/3L speed supported by the T2081NSE8P1B?
The T2081NSE8P1B supports DDR3/3L memory up to 2133 MT/s using its 64-bit interface with 72-bit ECC. This speed enables high-bandwidth access for packet buffering and OS operations, and requires careful PCB layout with matched trace lengths and proper termination to maintain signal integrity at rated data rates. The T2081NSE8P1B memory controller also supports JEDEC-standard low-power states to reduce dynamic power during idle periods.
Does the T2081NSE8P1B support hardware virtualization, and what components are included?
Yes, the T2081NSE8P1B supports comprehensive hardware virtualization including hypervisor privilege level, logical-to-real address translation offload, PAMU v2 I/O MMU with paging, vMPIC for virtual interrupt management, and vDMA for user-level DMA.

Is the T2081NSE8P1B pin-compatible with the T1042, and what does that mean for PCB design?
Yes, the T2081NSE8P1B uses a 780-pin BGA package with identical pinout and 0.8 mm pitch as the T1042, enabling direct PCB replacement without layout changes. This allows customers to reuse existing carrier boards while upgrading from quad-core e5500 to dual-threaded e6500 architecture-retaining investment in mechanical design, power delivery, and signal routing while gaining 28% higher clock frequency and full DPAA acceleration in the T2081NSE8P1B.
What Ethernet interfaces does the T2081NSE8P1B provide, and how are they configured?
The T2081NSE8P1B integrates up to two 10 Gb/s XFI/KR-capable MACs and seven 1 Gb/s SGMII MACs, multiplexed over its 8-lane SerDes. Configuration is done via RCW (Reset Configuration Word) fuses and U-Boot device tree bindings, allowing assignment of specific lanes to XFI, SGMII, PCIe, or SATA. No external PHY is needed for SGMII, and XFI supports direct connection to optical modules or backplane traces in the T2081NSE8P1B design.
