| 品牌：DIODES | 型号：PT7C4302WEX | 类型：时钟计时IC |
| 用途：*** | 封装：SOP8 | 包装：2500 |
| 应用领域：3C数码 |
PT7C4302WEX内部己有两个11P的匹配电容，外转电路只需匹配个32.768kHz的晶振就可以。
PT7C4302WEX DIODES SOP8用PT7C4302WEX芯片替代DS1302的时钟芯片,
是因为DALLS的市场假货太多了，进口原装DIODES芯片一个要10元左右，
国产贴牌的价格从0.5元到6元不等价格。国产的品质参差不齐，很难买到品质有***的时钟芯片。
为了解决客人***买到假货的难题，深圳市广益达电子有限公司推出用PT7C4302WEX 时钟芯片
替代DS1302，PT7C4302WEX的价格1.9元/颗，进口原装，品质好。
