T2081NXE8P1B

Overview

The T2081NXE8P1B 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, 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-threaded e6500 cores delivering high-performance processing with advanced power management capabilities
• Integrated CoreNet platform enabling efficient bandwidth allocation and priority sorting between endpoints
• Hardware-accelerated security functions including encryption, packet parsing, and queue management
• Flexible SerDes interface supporting multiple Ethernet speeds and protocol multiplexing

Applications

• Control plane processing in telecommunications infrastructure
• Integrated control and data plane handling in network equipment
• High-performance routing and switching applications
• Base station control units requiring low latency and high throughput

Procurement Notes

Verify the specific suffix E8P1B against official NXP documentation to confirm package type, temperature range, and mass storage options. Ensure compatibility with existing board designs regarding pinout and voltage requirements. Cross-reference the part number with current lifecycle status to avoid obsolescence risks during production planning.

Selection Notes

Select this component when upgrading from T1042 or P4080 platforms to achieve higher core density and SerDes bandwidth without significant power increases. Consider the T2081 over the T2080 if a smaller footprint is required, as it maintains pin compatibility with quad-core predecessors while offering enhanced multi-threading capabilities for complex protocol stacks.

Part Context

This processor belongs to the QorIQ T-series family, designed for mid-range communication applications. It bridges the gap between entry-level microcontrollers and flagship multicore processors like the T4 series. The T2081 variant specifically targets cost-sensitive deployments requiring robust networking features and secure data processing within compact form factors.

Replacement Considerations

Direct pin-compatible upgrades are available from the T1042 series. For increased performance, consider the T2080 or T4240 models, though these may require board redesign due to different pin counts and power specifications.
