【选型】可替换GD32F330G8U6TR的国产32位MCU AT32F421G8U7,120MHz更高主频,硬件一致
近期由于疫情原因、国际形势等因素导致电子器件的供货、价格等也比较动荡。之前采用STM32的用户也纷纷寻求替代物料,对于经历过缺货问题的客户来说多一个备选就多一分保障,不仅要有国产MCU替换进口MCU,也需要国产MCU之间能够做到替换备选,保证产品正常生产。国产雅特力的32位MCU AT32F421G8U7就是这样一款MCU,其可以替换知名度稍高的GD32F330G8U6TR,并具备一定的替换优势。
如下是雅特力的AT32F421G8U7与GD32F330G8U6TR的资源与引脚的对比图:
slib:安全库(Security Library)可支持密码保护指定范围程序区,烧录核心算法到此区域
通过以上可以看出,在硬件上二者是完全一致的,可以把GD32F330G8U6TR从板子上拿掉直接换上AT32F421G8U7,电气特性保持一致。在资源上AT32F421G8U7比GD32F330G8U6TR具备一定的优势,首先主频在120MHz,其次RAM也更大,这对于先前有出现RAM掣肘的用户来说就是福音。另外AT32F421G8U7支持slib,更具有安全性。
