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 C8051F520A-IM is
the C8051F520A-AM.
The -AM and -AT devices receive full automotive quality production status, including AEC-Q100 qualifica-
tion, registration with International Material Data System (IMDS) and Part Production Approval Process
(PPAP) documentation. PPAP documentation is available at www.silabs.com with a registered and NDA
approved user account. The -AM and -AQ devices enable high volume automotive OEM applications with
their enhanced testing and processing. Please contact Silicon Labs sales for more information regarding 
–AM and -AQ devices for your automotive project.
