New contact with a stm32f10 series chip, after downloading the library file from the official website, start to create a project. But the startup files don't know what to choose. They all start with 10, but the letters behind are different.
Presumably these letters represent different meanings. I didn't dare to choose at will, so I checked the information. I made a note here, and I forgot to look it up.
cl: interconnected products, stm32f105/107 series
vl: value-added products, stm32f100 series
xl: ultra-high-density products, stm32f101/103 series
ld: low-density products, FLASH less than 64K
md: medium-density products, FLASH=64 or 128
hd: high density product, FLASH greater than 128
