Am188ES and Am188EM Microcontrollers
Implementation
The SD188ES/SD188EM demonstration board supports the AMD Am188ES and
Am188EM microcontrollers. The board is shipped with either an Am188ES or
Am188EM microcontroller that operates at 40 MHz. Although not supported by
the on-board crystal, the Am188ES and Am188EM microcontrollers are also
available in 20-, 25-, and 33-MHz operating frequencies.
The Am188ES and Am188EM microcontrollers are designed to meet the most
common requirements of embedded products developed for the communications,
office automation, mass storage, and general embedded markets. Specific
applications include feature phones, cellular phones, PBXs, multiplexers, modems,
disk drive controllers, hand-held and desktop terminals, fax machines, line cards,
managed hubs, and industrial control. Refer to the Am186
ES and Am188
ES
Microcontrollers Data Sheet and the Am186
EM and Am188
EM
Microcontrollers Data Sheet for more information on the specific features of the
Am188ES and Am188EM microcontrollers.
See Figure 2-2 on page 2-5 for a block diagram detailing the Am188ES
microcontroller’s functionality. See Figure 2-3 on page 2-6
for a block diagram
detailing the Am188EM microcontroller’s functionality.
