Valid combinations list configurations planned to
be supported in volume for this device. Consult the
local AMD sales office to confirm availability of
specific valid combinations and to check on newly
released combinations.
Note: The industrial version of the Am186ES and
Am188ES microcontrollers, as well as the
Am186ESLV and Am188ESLV, are available in 20
and 25 MHz operating frequencies only.
The Am186ES, Am188ES, Am186ESLV, and
Am188ESLV microcontrollers are all functionally
the same except for their DC characteristics and
available frequencies.
