T2081NXE8T1B

Microprocessors Overview

The T2081NXE8T1B is a QorIQ T-series communication processor built on 28 nm technology. It features eight virtual cores, comprising four dual-thread e6500 processors running at up to 1.8 GHz with 6.0 DMIPS/MHz performance. The device includes a shared 2 MB L2 cache and integrates the CoreNet platform for coherent and non-coherent transactions. Key peripherals include two USB 2.0 controllers, SD/MMC/eMMC interfaces, and a 64-bit DDR3L/3L SDRAM controller supporting ECC. Security acceleration reaches 10 Gbps, while data path acceleration handles up to 17.5 Gbps. The processor supports eight SerDes channels operating at speeds up to 10 GHz.

Microprocessors Feature Summary

• Integrates eight virtual e6500 cores based on Power Architecture technology for high-performance processing.
• Includes integrated security acceleration (SEC) and decompression/compression acceleration (DCE) for efficient data handling.
• Features eight SerDes channels capable of operating at frequencies up to 10 GHz for high-speed connectivity.
• Supports multiple Ethernet MAC configurations including 10 Gb/s options via XFI/KR or XAUI interfaces.

Microprocessors Applications

• Control plane processing in telecommunications infrastructure
• Integrated control and data plane processing
• Network equipment requiring high-speed SerDes connectivity

Microprocessors Procurement Notes

Verify the specific suffix E8T1B against official NXP documentation to confirm package type, temperature range, and mass storage configuration. Ensure compatibility with existing board designs regarding pinout and power requirements when upgrading from legacy models like the T1042. Cross-reference ordering information directly with manufacturer datasheets to avoid discrepancies in component specifications.

Microprocessors Selection Notes

Select this model for applications requiring an upgrade path from quad-core devices like the T1042 without changing the PCB layout. It offers enhanced kernel processing power and SerDes bandwidth compared to previous generations while maintaining similar power consumption levels. Consider the T2081 variant specifically when seven Ethernet MACs are sufficient, providing a cost-effective solution relative to the eight-MAC T2080 version.

Microprocessors Part Context

The T2081NXE8T1B belongs to the QorIQ T2080/T2081 family, representing a mid-range platform within the Layerscape architecture. It incorporates architectural innovations from the flagship T4240 series, such as the e6500 core design. This family targets communication markets needing scalable performance, bridging the gap between lower-end T-series devices and higher-end P-series or T4-series processors.

Microprocessors Replacement Considerations

The T2081 serves as a direct pin-compatible replacement for the T1042, allowing for performance upgrades on existing boards. For systems requiring eight Ethernet MACs instead of seven, the T2080 is the functional equivalent within the same family. Verify software compatibility when migrating from older T-series or P-series devices due to architectural differences in the CoreNet platform.
