communications, a direct bus interface, and integrated

memory.

The Am186ER and Am188ER microcontrollers

integrate memory and the functions of the CPU,

nonmultiplexed address bus, timers, chip selects,

interrupt controller, DMA controller, PSRAM controller,

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 drives, hand-held terminals

and desktop ter minals, fax machines, printers,

photocopiers, and industrial controls.
