你好
我正在查看 i.MX 数据表，经常看到以 NVCC_* 开头的引脚名称。
能否请您解释一下 NVCC 代表什么？
此外，名称中包含 NVCC 的徽章有何意义？
感谢您的支持。
顺祝商祺！
您指的是哪种产品？ NVCC 是"Nominal Voltage Common Collector" 的缩写，NVCC_* 引脚是为一组 I/O 焊盘（如 GPIO、UART、SPI 等）提供电压的电源引脚。
如 NVCC_SD 为 SD 卡接口引脚供电。
你好，丽塔、
谢谢您的解释。我所指的产品是 i.MX93。
我知道 NVCC 代表标称电压共集电极，而 NVCC_* 引脚是为特定 I/O 组（如 GPIO、UART、SPI）提供电压的电源引脚。NVCC_SD 为 SD 卡接口供电的例子非常有用。
感谢您的支持。
致以最诚挚的问候，
tkato
