Product details
Overview
T4161NSE7QTB from NXP Semiconductors is a 16-virtual-core, dual-threaded Power Architecture e6500-based communications processor fabricated on 28 nm process technology, delivering up to 1.8 GHz core frequency, 4 MB L2 cache, and dual 64-bit DDR3L memory controllers supporting 1866 MT/s - deployed in carrier-grade routers, NFV infrastructure, and secure storage controllers.
For engineers reviewing the T4161NSE7QTB datasheet, T4161NSE7QTB pinout, T4161NSE7QTB application, or T4161NSE7QTB equivalent, key selection criteria include its dual-threaded e6500 core architecture, DPAA hardware acceleration (FMAN/QMAN/BMAN/SEC), SerDes lane count (24 lanes), virtualization support (hypervisor privilege level + PAMUv2), and 2×10 GbE + 13×1 GbE Ethernet MAC configuration.
Technical Context
The T4161NSE7QTB implements eight physical e6500 cores arranged in two clusters of four, each sharing 2 MB L2 cache, with full AltiVec SIMD support and 7 DMIPS/MHz per core. It integrates CoreNet coherency fabric with 1 MB platform cache and supports hardware-assisted virtualization via hypervisor privilege mode, logical-to-real address translation, and IOMMU-enforced DMA protection.
Its DPAA subsystem includes FMAN 1.1 for packet parsing/classification at 50 Gbit/s, QMAN 1.1 for hierarchical queue scheduling, BMAN 1.1 for buffer pool management, SEC 5.0 for cryptographic acceleration (40 Gbit/s AES/3DES), PME 2.0 for 10 Gbit/s RegEx matching, and DCE 1.0 for 20 Gbit/s compression/decompression.

Yes, the T4161NSE7QTB includes comprehensive hardware virtualization support: an extra hypervisor privilege level, hardware-accelerated logical-to-real address translation, PAMUv2 IOMMU for DMA protection, vMPIC for virtual interrupt handling, and vDMA for user-level data movement. These features enable secure, high-performance virtualized environments such as KVM-based NFV deployments running on the T4161NSE7QTB.
What memory interfaces does the T4161NSE7QTB provide?
The T4161NSE7QTB integrates two 64-bit DDR3L memory controllers supporting data rates up to 1866 MT/s, with ECC and interleaving support. This configuration delivers ≥25.6 GB/s aggregate bandwidth and enables robust, error-corrected memory subsystems for telecom and defense applications. The T4161NSE7QTB does not support LPDDR or DDR4; DDR3L is the sole supported memory standard per its validated design.
How many Ethernet MACs does the T4161NSE7QTB support?
The T4161NSE7QTB supports a total of 15 Ethernet MACs: two 10 Gigabit Ethernet (10 GbE) MACs and thirteen 1 Gigabit Ethernet (1 GbE) MACs. These are implemented in dual Frame Managers (FMANs) and connect to external PHYs via SGMII, QSGMII, XFI, or 10Gbase-KR. This MAC count matches the documented T4160 variant specification and is fixed for the T4161NSE7QTB.
Is the T4161NSE7QTB pin-compatible with other QorIQ T4 family processors?
Yes, the T4161NSE7QTB shares the same 1296-pin FC-BGA package and pinout as the T4240NSE7QTB and T4080NSE7QTB, enabling migration across the T4 family with no PCB redesign. This pin compatibility covers power, clock, DDR, SerDes, PCIe, and peripheral interfaces - allowing hardware reuse while scaling core count and I/O resources. The T4161NSE7QTB leverages this common footprint for flexible platform development.
