GL3232-ONY04     QFN6X6-48

创惟科技发表业界最快的UHS-I读卡机控制芯片- GL3232，搭配全新发表的400GB SanDisk Extreme® UHS-I microSDXC card读取速度可达到160MB/s

GL3232 是一颗可支持400GB SanDisk Extreme® UHS-I microSDXCTM card的读卡机控制芯片，也是最快的UHS-I读卡机，主要的优点如下：

1. GL3232是基于UHS-I接口，利用创惟设计的传输技术提升读写速度，数据传输率可达200 MB/s。GL3232实际测试400GB SanDisk Extreme® UHS-I microSDXCTM card可达160MB/s，是目前SDR104速度模式的两倍。

2. GL3232兼容于传统的SD 3.0记忆卡连接器，SD信号走线的设计原则与SD 3.0相同，也不需要增加额外组件，客户可以轻易的将产品的速度升级至却不会增加外围组件的成本。

3. GL3232内建5V/1.2V DC-DC以提升电源效率，降低产品功耗，比起传统LDO可提升55%的电源效率，有效降低读卡机工作时的温度。

GL3232将UHS-I速度提升一倍，却仍保有UHS-I的成本竞争力，并降低一半的芯片功耗，提供业界的UHS-I读卡机解决方案。
