BU94501AMUV-E2

Overview

The BU94501AMUV-E2 is a silicon monolithic integrated circuit designed as an audio decoder LSI. It integrates a USB 2.0 Full Speed host interface, SD card I/F, and an internal system controller. The device supports decoding of WAV, AAC, WMA, and MP3 formats with sample rates up to 48 kHz. It features a built-in audio DAC for line outputs and digital audio interfaces including I2S, EIAJ, and S/PDIF. Operating at a supply voltage of 3.6 V, it utilizes a VQFN-40 package (VQFN040V6060) measuring 6.00mm x 6.00mm x 1.00mm.

Feature Summary

Integrates USB host and SD card interfaces for media access
Supports multiple audio decoding standards including MP3, WMA, and AAC
Includes internal system controller and FAT analysis capabilities
Provides analog line outputs and digital audio output options

Applications

Audio playback devices utilizing USB mass storage
Portable music players supporting SD memory cards
Embedded audio systems requiring protocol conversion

Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm RoHS compliance details via the manufacturer datasheet. Ensure design compatibility with the VQFN-40 package dimensions and thermal requirements before integration into final products.

Selection Notes

Select this model when iPod support is not required, as it lacks automatic enumeration for Apple devices. Verify that the application does not require DRM file support, which is explicitly excluded. Ensure the design accommodates the specific 16.9344MHz crystal oscillator requirements for the PLL block.

Part Context

This component belongs to the BU9450xAxxx series manufactured by ROHM Semiconductor. It shares core decoding and interface functionalities with the BU94502AMUV but differs in iPod compatibility features. The series is categorized under Audio CODECs and Interface ICs within the manufacturer's portfolio.
