XUF208-128-QF48-I10

Microcontrollers Overview

The XUF208-128-QF48-I10 is a 32-bit microcontroller from the XMOS XU series, built on the XCore architecture. It features an eight-core processor with a speed of 1000 MIPS and includes 128 KB of RAM. The device utilizes a 48-UQFN (6x6 mm) package with 27 I/O pins. It operates within a voltage range of 0.95 V to 3.6 V and supports an industrial temperature range of -40°C to 85°C.

Microcontrollers Feature Summary

• Integrates eight parallel processing cores for deterministic low-latency execution
• Supports flexible input/output configuration via software-defined hardware peripherals
• Provides native USB connectivity with asynchronous clocking capabilities

Microcontrollers Applications

• USB audio interfaces and digital-to-analog converters
• Portable audio decoding devices
• Mobile recording sound cards

Microcontrollers Procurement Notes

Verify the specific suffix 'I10' confirms the industrial temperature grade (-40°C to 85°C). Confirm the package type matches the 48-UQFN form factor. Ensure compatibility with the required operating voltage range of 0.95 V to 3.6 V. Check for any specific firmware or toolchain requirements associated with the XU series architecture.

Microcontrollers Selection Notes

Select this component when a compact footprint is required alongside multi-core processing power. The XU208 series offers a balance of performance and pin count suitable for embedded audio applications. Consider the ROMless nature if external memory integration is planned. Evaluate the thermal characteristics of the small QFN package for the target enclosure.

Microcontrollers Part Context

This part belongs to the XMOS XU series, which extends the XCore architecture for mainstream embedded applications. The XU208 variant specifically targets cost-sensitive designs requiring multiple cores and USB functionality without integrated program memory. It serves as a bridge between high-end AI chips and basic MCUs.

Microcontrollers Replacement Considerations

Direct substitutes include other XU208 variants with different packages, such as XU208-128-TQ128-I10 for larger footprints. Cross-series migration to XL208 requires verification of memory architecture differences, as XL parts are often ROMless.
