Am2900 Bipolar Microprocessor family

The Am2900 Bipolar Microprocessor family provides LSI building blocks applicable to numerous high-speed system configurations. The building blocks in this family handle the data path signals, the microprogram control functions, the input/output bus interconnections and the interrupt and timing/control requirements applicable to most digital systems. These building blocks are well suited for computer or central processor emulation, peripheral controllers, communications and voice processors, and special dedicated digital signal processors. This paper describes the functional characteristics of the first group of Am2900 devices to be introduced. This family of circuits operates with standard bipolar RAMs, ROMs, and PROMs as the memory elements. The advantage of using bipolar microprocessor circuit configurations is, of course, the operating speed and the flexibility associated with the microprogrammed architecture.
