GL3232-ONY04     QFN6X6-48

創(chuàng)惟科技發(fā)表業(yè)界最快的UHS-I讀卡機控制芯片- GL3232，搭配全新發(fā)表的400GB SanDisk Extreme® UHS-I microSDXC card讀取速度可達到160MB/s

GL3232 是一顆可支持400GB SanDisk Extreme® UHS-I microSDXCTM card的讀卡機控制芯片，也是最快的UHS-I讀卡機，主要的優(yōu)點如下：

1. GL3232是基于UHS-I接口，利用創(chuàng)惟設計的傳輸技術(shù)提升讀寫速度，數(shù)據(jù)傳輸率可達200 MB/s。GL3232實際測試400GB SanDisk Extreme® UHS-I microSDXCTM card可達160MB/s，是目前SDR104速度模式的兩倍。

2. GL3232兼容于傳統(tǒng)的SD 3.0記憶卡連接器，SD信號走線的設計原則與SD 3.0相同，也不需要增加額外組件，客戶可以輕易的將產(chǎn)品的速度升級至卻不會增加外圍組件的成本。

3. GL3232內(nèi)建5V/1.2V DC-DC以提升電源效率，降低產(chǎn)品功耗，比起傳統(tǒng)LDO可提升55%的電源效率，有效降低讀卡機工作時的溫度。

GL3232將UHS-I速度提升一倍，卻仍保有UHS-I的成本競爭力，并降低一半的芯片功耗，提供業(yè)界的UHS-I讀卡機解決方案。
