Freescale MC68302FC25C

M6800025MHzDRAM0°C ~ 70°C（TA）

Overview

The MC68302FC25C integrated multiprotocol processor (IMP) is a very large-scale integration (VLSI) device incorporating the main building blocks needed for the design of a wide variety of controllers. The device is especially suitable to applications in the communications industry. The IMP is the first device to offer the benefits of a closely coupled, industry-standard M68000 microprocessor core and a flexible communications architecture. The IMP may be configured to support a number of popular industry interfaces, including those for the Integrated Services Digital Network (ISDN) basic rate and terminal adaptor applications. Concurrent operation of different protocols is easily achieved through a combination of architectural and programmable features. Data concentrators, line cards, modems, bridges, and gateways are examples of suitable applications for this device. The IMP is a high-density complementary metal-oxide semiconductor (HCMOS) device consisting of an M68000 microprocessor core, a system integration block (SIB), and a communications processor (CP).
