T2081NXN8T1B

Overview

The T2081NXN8T1B is a QorIQ T-series communication processor built on 28 nm technology. It features eight virtual cores based on the e6500 architecture, operating at up to 1.8 GHz with 6.0 DMIPS/MHz performance. The device includes a shared 2 MB L2 cache and integrates CoreNet platform interconnects for coherent and non-coherent transactions. Key peripherals include two USB 2.0 controllers, enhanced SD/MMC/eMMC interfaces, and four I²C controllers. Memory support is provided by a 64-bit DDR3L/3L SDRAM controller with ECC. Security acceleration reaches 10 Gbps, while data compression/decompression accelerates up to 17.5 Gbps.

Feature Summary

• Eight virtual e6500 cores delivering high-performance processing with advanced power management capabilities
• Integrated CoreNet platform supporting priority-based bandwidth allocation and transaction coherence
• Hardware-accelerated security functions including encryption, packet parsing, and queue management
• Multi-channel SerDes interface supporting high-speed Ethernet connectivity options

Applications

• Control plane processing in telecommunications infrastructure
• Integrated control and data plane applications
• Network equipment requiring high-speed packet processing
• Upgrades from legacy P4080 or T1042 platforms

Procurement Notes

Verify the complete part number against official NXP documentation to ensure correct suffix alignment. Confirm that the specific package variant matches your board design requirements. Check for any applicable RoHS compliance statements in the latest datasheet. Ensure compatibility with existing software drivers for the T-series architecture before procurement.

Selection Notes

Select this component when upgrading from T1042 or P4080 devices to gain higher core count and bandwidth without significant power increases. Consider the T2081 over T2080 if fewer SerDes lanes are required but pin compatibility with smaller packages is needed. Evaluate the integrated security engines if hardware acceleration for encryption is critical for system throughput.

Part Context

This processor belongs to the QorIQ T-series family, which incorporates architectural innovations from the flagship T4240. It serves as a mid-range solution bridging the gap between lower-end T-series chips and high-end P-series processors. The T2081 specifically offers a compact form factor compared to the T2080, maintaining compatibility with designs originally intended for quad-core devices like the T1042.
