1.1. Ordering Information
The following features are common to all devices in this family:
Table 1.1 shows the features that differentiate the devices in this family.
All devices in Table 1.1 are also available in an automotive version. For the automotive version, the -I in the
ordering part number is replaced with -A. For example, the automotive version of the C8051F520-C-IM is
the C8051F520-C-AM.
The -AM and -AT devices receive full automotive quality production status, including AEC-Q100 qualifica-
tion (fault coverage report available upon request), registration with International Material Data System
(IMDS) and Part Production Approval Process (PPAP) documentation. PPAP documentation is available at
www.silabs.com
volume automotive OEM applications with their enhanced testing and processing. Please contact Silicon
Labs sales for more information regarding -AM and -AT devices for your automotive project.
