富威集團代理產線ALi推出穩定、低成本的M567x系列車載音頻播放器解決方案

 2010-12-01
富威集團代理產線ALi M567x系列晶片,採用ALi卓越RF、CD-DSP技術,集成了DAC、ADC及8051控制內核於一體,僅需少量的外部元器件,即可設計出高性能的音頻播放產品。可播放來自SD/MMC Card、USB存儲器、以及光碟當中的音頻檔。

揚智科技(ALi)是一家專業的晶片設計公司,憑藉著技術創新、效能卓越及完整解決方案,奠定該公司在數位機頂盒與多媒體播放器的市場領先地位。ALi致力於發展數位娛樂平臺技術,專注於客廳、行動及車載的整合式消費性電子產品市場。在光碟伺服領域ALi具有更加明顯的技術優勢,在各種機芯匹配、ESP及讀碟性能上都能一直保持領先地位。

富威集團可依客戶各別需求,提供功能完善的軟體開發包及硬體設計參考資料,方便客戶在極短時間內完成產品設計,將產品儘快投入市場。另外,ALi以功能完整的程式軟體為基礎,再植入DSA通訊協議,外部MCU只需通過DSA通訊向M5673D發送簡單的操作命令即可實現相關功能,產品設計時不需要花時間去瞭解M5673D的內部程式,就可以開發出功能完善穩定可靠的產品。我們也可根據客戶需要為客戶提供完整的軟體、硬體設計開發。

如客戶不需要SD/MMC Card及USB功能,可選擇成本更低的M5672晶片,該晶片除了不支援 Card及USB以外其他功能與M5673D相同。以下是關於M5673D晶片的基本功能介紹。
