Product details
Overview
T4081NSN7PQB from NXP Semiconductors is a quad-core, dual-threaded Power Architecture e6500-based communications processor fabricated in 28 nm process technology, delivering up to 1.8 GHz core frequency, 2 MB L2 cache per cluster, and integrated Data Path Acceleration Architecture (DPAA) supporting 2 × 10 GbE + 10 × 1 GbE MACs. It targets high-throughput control-and-data-plane processing in network infrastructure.
For engineers reviewing the T4081NSN7PQB datasheet, T4081NSN7PQB pinout, T4081NSN7PQB application, or T4081NSN7PQB equivalent, key selection considerations include its dual-threaded e6500 core architecture, DDR3L-1866 memory controller support, SerDes lane count (24 lanes), PCIe 2.0/3.0 controller count (3), and hardware virtualization features including hypervisor privilege level and PAMUv2 I/O MMU.
Technical Context
The T4081NSN7PQB implements four dual-threaded e6500 cores clustered with shared 2 MB L2 cache and 1 MB CoreNet Platform Cache, operating up to 1.8 GHz with AltiVec SIMD engine and 7 DMIPS/MHz per core. It integrates two DDR3L memory controllers supporting 1866 MT/s with ECC and interleaving.
Its DPAA subsystem includes Frame Manager (FMAN 1.1), Queue Manager (QMAN 1.1), Buffer Manager (BMAN 1.1), Security Engine (SEC 5.0 at 40 Gbit/s), Pattern Matching Engine (PME 2.0 at 10 Gbit/s), and Data Compression Engine (DCE 1.0 at 20 Gbit/s). The 24-lane SerDes supports SGMII, QSGMII, XAUI, PCIe 3.0, SRIO, and Interlaken-LA protocols.

Equivalent & Alternatives
The following parts are listed as comparable options for similar multicore communications processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| T4080NSN7PQB | Same core count (4), identical package and pinout, but lacks SEC 5.0 cryptographic acceleration block | Not suitable for applications requiring hardware-accelerated AES-256 or Kasumi/F8 cipher suites | Select T4081NSN7PQB when full DPAA security acceleration is required; T4080NSN7PQB suffices for non-crypto control-plane use |
| T4160NSN7PQB | 8-core (16-thread) variant in same FC-BGA-1932 package, with 4 MB L2 cache and 3 DDR controllers | Higher throughput for data-plane intensive roles (e.g., deep packet inspection, DPI), but higher power draw (15–25 W vs. 12–18 W) | Choose T4160NSN7PQB when scaling beyond 20 Gbit/s aggregate packet processing; retain T4081NSN7PQB for cost- and power-sensitive edge deployments |
Compared with T4080NSN7PQB, T4081NSN7PQB adds full SEC 5.0 crypto acceleration without changing pinout or thermal envelope; compared with T4160NSN7PQB, it trades core count and DDR bandwidth for lower static power and smaller BOM footprint - making it optimal for compact, secure, mid-bandwidth edge platforms.

FAQ
What is the maximum DDR3L speed supported by T4081NSN7PQB?
The T4081NSN7PQB supports DDR3L memory at up to 1866 MT/s across two 64-bit controllers with ECC and interleaving enabled. This speed is achievable with JEDEC-compliant DDR3L-1866 modules and proper PCB layout adherence to NXP's signal integrity guidelines. The T4081NSN7PQB DDR controller includes built-in training and calibration logic to maintain timing margins across voltage and temperature variations.
Does T4081NSN7PQB support PCIe 3.0 Gen3 signaling?
Yes, the T4081NSN7PQB supports PCIe 3.0 Gen3 signaling across all three PCIe controllers, with configurable lane widths (x1/x2/x4/x8) and endpoint SR-IOV capability (2 PFs, 128 VFs). Each controller complies with PCI Express Base Specification Revision 3.0 and supports ASPM L0s/L1 power states. Link training and equalization are handled in hardware without firmware intervention.
How many Ethernet MACs does T4081NSN7PQB integrate, and what speeds are supported?
The T4081NSN7PQB integrates a total of 12 Ethernet MACs: two 10 GbE (10GBASE-KR, XFI, SFP+) and ten 1 GbE (RGMII, SGMII, QSGMII, HiGig2) interfaces. All MACs are managed by dual Frame Managers (FMANs) with hardware-assisted scheduling, policing, and congestion management. No external PHY is required for RGMII/SGMII modes, but 10 GbE interfaces require external KR/XFI PHYs.
Is T4081NSN7PQB pin-compatible with other QorIQ T4 family processors?
Yes, T4081NSN7PQB is pin-compatible with T4080NSN7PQB and T4160NSN7PQB in the FC-BGA-1932 package. All share identical mechanical footprint, power delivery pin assignments, and SerDes/PCIe/DDR interface pinouts. Software and board design can be reused across these variants, with differentiation limited to core count, cache size, and accelerator presence - verified in NXP document AN4943 "T4 Family Pin Compatibility Guide".
What virtualization technologies are supported by T4081NSN7PQB?
T4081NSN7PQB supports hardware-assisted virtualization via Power Architecture e6500 hypervisor privilege level, PAMUv2 I/O MMU for DMA protection, vMPIC for virtual interrupt handling, and vDMA for user-level data movement. It is validated with KVM, Linux containers, and commercial hypervisors from Enea, Green Hills, Mentor Graphics, and Wind River - enabling secure, low-overhead partitioning of control and data plane functions.
