Product details
Overview
T2081NSE7PTB from NXP 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 780-pin 23 × 23 mm FC-BGA package. It delivers up to 224 hardware queues, 10 Gb/s cryptography acceleration (SEC), and supports up to seven 1 Gb/s MACs and two 10 Gb/s XFI/KR MACs - deployed in enterprise switches, LTE control cards, and industrial SBCs.
For engineers reviewing the T2081NSE7PTB datasheet, T2081NSE7PTB pinout, T2081NSE7PTB application, or T2081NSE7PTB equivalent, key selection considerations include SerDes lane count (8 vs. 16), PCIe Gen3/Gen2 mix (1× Gen3 + 3× Gen2), absence of SATA/RapidIO/Aurora, and pin compatibility with T1042 for board reuse in scalable product families.
Technical Context
The T2081NSE7PTB implements a coherent CoreNet interconnect fabric linking four e6500 cores, 2 MB shared L2 cache, 512 KB platform cache with prefetch, and DPAA subsystem (FMAN/QMAN/BMAN/SEC/DCE). Its virtualization support includes hypervisor privilege level, PAMU v2 I/O MMU, and vMPIC/vDMA for guest-isolated resource management.
Hardware acceleration is tightly coupled to networking data paths: FMAN parses and classifies packets at up to 24 Gb/s; QMAN schedules work across 224 queues with strict ordering; SEC provides AES/SHA/RSA acceleration up to 10 Gb/s; DCE handles LZS/LZ77 compression/decompression at up to 17.5 Gb/s - all operating under deterministic latency constraints suitable for control-plane–intensive applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| e6500 Core Count | Four dual-threaded 64-bit Power Architecture® cores - enables 8 virtual threads for concurrent control/data plane tasks without software threading overhead. |
| Max Clock Frequency | 1.8 GHz - sustains high-throughput packet classification and crypto operations while maintaining sub-100 ns interrupt latency. |
| L2 Cache | 2 MB shared banked cache - reduces inter-core coherency traffic and accelerates shared control-plane code execution. |
| DPAA Queue Capacity | 224 hardware queues - supports fine-grained QoS scheduling across multiple virtual machines or service instances. |
| Crypto Throughput | 10 Gb/s SEC acceleration - offloads IPsec/TLS encryption from CPU, freeing >3 cores for application logic in UTM or router control planes. |
| MAC Interfaces | 7 × 1 Gb/s SGMII + 2 × 10 Gb/s XFI/KR - enables compact 2-port 10G + 7-port 1G switch designs without external PHYs or retimers. |
| PCIe Interface | 1 × Gen3 + 3 × Gen2 endpoints - supports NVMe storage, FPGA co-processing, or multi-function mezzanine cards with bandwidth tiering. |
| Package | 23 mm × 23 mm, 780-pin FC-BGA, 0.8 mm pitch - matches T1042 footprint for drop-in upgrade on existing boards with no layout change required. |
Pinout & Package
23 mm × 23 mm, 780-pin Fine-Pitch Flip-Chip Ball Grid Array (FC-BGA) with 0.8 mm pitch, thermally enhanced with exposed thermal pad. Pinout conforms to NXP's T2081-specific ball map documented in T2080FS Rev 2, supporting full signal integrity compliance for DDR3L, PCIe, SGMII/XFI, and I²C/UART interfaces.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD_DDR | DDR3L memory I/O supply | 1.35 V regulated rail - must be sequenced after core power and synchronized with DDR controller initialization. |
| CLKIN | Differential system clock input | 100 MHz differential reference - drives internal PLLs for CPU, DDR, and SerDes domains with <500 fs jitter tolerance. |
| RESET_REQ_B | Asynchronous active-low reset request | Drives cold reset sequence - asserts full chip reset including DDR controller, SerDes, and DPAA blocks; requires 100 ms debounce. |
| BOOT_CFG[7:0] | Strap pins for boot source selection | Configures primary boot device (NOR/NAND/SD/eMMC/SPI flash) and bus width - latched at power-on reset only. |
| PCIE_TX[3:0]/RX[3:0] | PCIe Gen2/Gen3 differential lanes | Four independent SerDes lanes - each configurable as Gen2 endpoint or Gen3 endpoint; supports hot-plug and AER reporting. |
| SGMII_RX[6:0]/TX[6:0] | Seven 1 Gb/s Ethernet PHY interfaces | Embedded SerDes with integrated terminations - eliminates need for external magnetics in cost-sensitive SBC or control card designs. |
Key Features
| Feature | Design Value |
|---|---|
| Hardware Virtualization Support | Hypervisor privilege level + PAMU v2 I/O MMU enables secure, isolated VMs for mixed control/data plane workloads without software-based address translation overhead. |

FAQ
What is the maximum DDR3L speed supported by T2081NSE7PTB?
T2081NSE7PTB supports DDR3L SDRAM up to 2133 MT/s with 64-bit bus width and 72-bit ECC. The memory controller implements adaptive read/write leveling and on-die termination calibration to maintain signal integrity across temperature and voltage variations - critical for sustained throughput in carrier-grade control plane applications where T2081NSE7PTB operates.
Does T2081NSE7PTB support PCIe Gen3 x4 mode?
No, T2081NSE7PTB supports one PCIe Gen3 controller configurable as x1, x2, or x4 endpoint, plus three PCIe Gen2 controllers. The Gen3 link operates at 8 GT/s with ASPM L1 substates and AER reporting - sufficient for NVMe boot drives or FPGA co-processors, unlike T2080 which offers dual Gen3 links. This configuration is fully implemented in T2081NSE7PTB silicon.
Is T2081NSE7PTB pin-compatible with T1042 processors?
Yes, T2081NSE7PTB is explicitly designed as a pin-compatible upgrade for T1042, sharing identical 780-pin FC-BGA mechanical footprint, power delivery scheme, and critical signal mapping. NXP documentation confirms no PCB changes are required for migration - a key design advantage leveraged in T2081NSE7PTB's target applications like modular switch control cards.
What virtualization software is validated for T2081NSE7PTB?
T2081NSE7PTB supports KVM hypervisor, Linux containers, and the NXP hypervisor - all validated with NXP Linux SDK releases. Hardware features including PAMU v2, vMPIC, and vDMA are enabled in these stacks to provide memory isolation, interrupt virtualization, and user-mode DMA - essential capabilities confirmed in T2081NSE7PTB reference deployments for network function virtualization.
Can T2081NSE7PTB boot from eMMC directly?
Yes, T2081NSE7PTB includes an enhanced SDXC/eMMC host controller supporting HS400 mode and boot-from-eMMC functionality. BOOT_CFG straps configure eMMC as primary boot device with 8-bit wide interface and automatic partition scanning - a capability verified in T2081NSE7PTB production firmware images and used in industrial SBC designs to eliminate NOR flash.
