6 SUPPLY, RESET AND CLOCK MANAGEMENT
The ST72104G, ST72215G, ST72216G and
ST72254G microcontrollers include a range of util-
ity features for securing the application in critical
situations (for example in case of a power brown-
out), and reducing the number of external compo-
nents. An overview is shown in
