T2081NSN8P1B

Microprocessors Overview

The T2081NSN8P1B is a QorIQ T2081 communication processor manufactured by NXP Semiconductors. It features four dual-thread e6500 cores based on Power Architecture technology, operating at frequencies 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 support, and an integrated flash controller. Network capabilities consist of eight SerDes channels (up to 10 GHz) and seven Ethernet MACs, supporting up to four 10 Gb/s interfaces. Acceleration features encompass DPAA with FMAN, QMAN, BMAN, SEC, DCE, and PME.

Microprocessors Procurement Notes

Verify the specific suffix NSN8P1B against official NXP documentation to confirm package type, temperature range, and compliance status. Ensure compatibility with existing board layouts when upgrading from T1042 platforms. Confirm software support availability for the selected core configuration and peripheral set before finalizing procurement decisions.

Microprocessors Selection Notes

Select this component for applications requiring significant kernel processing power and high SerDes bandwidth within a mid-range form factor. It serves as a direct pin-compatible upgrade for T1042 users needing enhanced performance without redesigning the PCB. Consider the T2080 variant if additional RapidIO messaging or higher SerDes frequency is required, noting the difference in package size and pin count.

Microprocessors Part Context

The T2081 is part of the QorIQ T-series family, designed as a smaller version of the T2080. It shares the same architectural innovations as the flagship T4240 but targets mid-range communication markets. The processor is positioned to succeed earlier P-series devices like the P3041 and P2041, offering improved performance per watt. Its design facilitates easy migration for customers moving from quad-core solutions to octa-core virtual thread architectures.

Microprocessors Replacement Considerations

The T2081 is pin-compatible with the T1042, allowing for direct upgrades in existing designs. For higher performance requirements, the T2080 offers additional SerDes channels and RapidIO support but requires a larger package. No other direct substitutes are documented; migration should be evaluated based on specific bandwidth and interface needs.
