Section : In order to meet environmental requirements, ST offers these
devices in different grades of ECOPACK packages, depending on their
level of environmental compliance. ECOPACK specifications, grade
definitions and product status are available at: www.st.com. ECOPACK
is an ST trademark. changed to LQFP with no exposed pad.
