The chip model is usually composed of three modules. The brand series is followed by parameters, as well as temperature, speed and
packaging information. The three modules form a formula that can resolve the naming of most chips.From this we can take a look at the
ST model. STM32F is the signature prefix of ST brand products. 205 is the series. Here is the first part of the brand plus series. R represents
the number of pins and E represents the memory 512kb. This part corresponds to In the middle of our parameters, T represents the LQFP
package, and 6 represents the temperature, which corresponds to the third part. There are other special suffixes in the picture and text
that represent the chip version and packaging, which correspond to our temperature, speed and packaging information.
