BU94702KV-E2

Overview

The BU94702KV-E2 is a silicon monolithic integrated circuit serving as an MP3 encoder and WAV/AAC/WMA/MP3 decoder LSI. It integrates a USB host interface, SD card I/F, audio DAC, system controller, and internal regulator. The device supports USB Full Speed (12Mbps) communication via the mass storage class and operates on a 3.0V to 3.6V supply voltage. It features a VQFP80 package with dimensions of 14.00mm x 14.00mm x 1.60mm. Electrical characteristics include a typical operating current of 51mA during USB playback and 26mA during SD card playback. The signal-to-noise ratio is typically 96dB at 1kHz with A-weighting.

Feature Summary

Integrates MP3 encoding capabilities alongside decoding functions for various audio formats including WMA, AAC, and WAV.
Contains a built-in USB Full Speed host interface supporting the mass storage class without external hubs.
Includes an SD card interface compatible with SPI mode, supporting SDHC, MMC, and mini-SD cards.
Features protocol conversion between I2C and USB HID for master microcomputer communication.

Applications

Audio products requiring portable music playback and recording
Devices utilizing USB memory or SD memory cards for media storage
Systems requiring direct control via I2C command interface

Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm that the specific ordering suffix matches the required packaging configuration. Ensure compliance with RoHS standards and check for any end-of-life notifications prior to finalizing procurement plans.

Selection Notes

Select this model when both MP3 encoding and decoding are required within a single chip. Ensure the design accommodates the VQFP80 package footprint and provides the necessary 16.9344MHz crystal oscillator connections. Verify that the application supports USB Full Speed devices and does not require high-speed USB connectivity.

Part Context

This component belongs to the BU94605AKV, BU94607AKV, BU94702AKV, and BU94705AKV series. It shares the same VQFP80 package and core architecture but differs in feature sets such as iPod support and CD-ROM interfaces found in other variants.

Replacement Considerations

BU94705AKV offers similar functionality with added iPod support and CD-ROM decoding capabilities. BU94607AKV includes iPod support but lacks the MP3 encoding function present in the BU94702KV-E2.
