AT32UC3B0128AU-Z2UR

Microcontrollers Overview

The AT32UC3B0128AU-Z2UR is a 32-bit microcontroller from the AVR UC3 B series, designed for audio applications. It features an AVR32 core with 128 KB of flash memory and 32 KB of RAM. The device operates at a maximum clock frequency of 60 MHz and supports a supply voltage range of 1.65 V to 3.6 V. It includes a 10-bit ADC and provides 44 I/O pins. The component is housed in a QFN-64 package.

Microcontrollers Feature Summary

• Licensed audio firmware IP cores including proprietary communication protocols for Apple devices and MP3, WMA, or AAC decoders
• 100% software compatible with standard AT32UC3B0128 counterparts for user code execution
• Integrated peripherals direct memory access controller for efficient data transfer between modules

Microcontrollers Applications

• Audio processing systems requiring licensed codec integration
• Portable media players utilizing specific audio protocol implementations
• Embedded audio controllers needing high-performance DSP capabilities

Microcontrollers Procurement Notes

Verify that the specific application requires the licensed audio IP cores, as these are exclusive to the AU suffix variants. Confirm that the development environment supports the AVR UC3 architecture. Ensure the design utilizes the QFN-64 package footprint. Check if standard equivalents suffice if audio-specific firmware is not utilized.

Microcontrollers Selection Notes

Select this variant specifically when the design necessitates the execution of licensed audio firmware IP cores such as iPod or iPhone communication protocols. Standard AT32UC3B0128 devices lack the hardware authorization for these specific IP cores. If only general-purpose processing is required, standard versions offer identical performance without the audio licensing constraints.

Microcontrollers Part Context

This component belongs to the Atmel AVR UC3 B series of 32-bit microcontrollers. It is part of a family optimized for cost-sensitive embedded applications requiring high code density and low power consumption. The AU designation identifies it within the specialized audio subset of the UC3 lineup, distinguishing it by firmware compatibility rather than architectural differences.

Microcontrollers Replacement Considerations

Standard AT32UC3B0128 devices are functionally equivalent for general code but cannot execute licensed audio IP cores. Verify if the specific audio firmware requirements can be met by alternative Microchip solutions if the legacy UC3 series is discontinued.

Microcontrollers FAQ

Can standard AT32UC3B0128 microcontrollers run the same user code as the AT32UC3B0128AU-Z2UR?

Yes, the datasheet states that audio parts are 100% compatible with standard devices regarding user code.

What distinguishes the AT32UC3B0128AU-Z2UR from the standard AT32UC3B0128?

The primary distinction is the ability to execute licensed audio firmware IP cores, such as MP3 decoders and proprietary communication protocols, which will not run on standard microcontrollers.

Does the AU suffix change the electrical specifications or pinout?

No, the technical information refers to the standard counterpart's datasheet, indicating no changes to electrical parameters or physical layout.
