The Am186CC embedded communications controller is the first member in the AMD Comm86 product family. The Am186CC controller is a costeffective, high-performance microcontroller solution for communications applications. This highly integrated microcontroller enables customers to save system costs and increase performance over 8-bit microcontrollers and other 16-bit microcontrollers. The Am186CC communications controller offers the advantages of the x86 development environment’s widely available native development tools, applications, and system software. Additionally, the controller uses the industry-standard 186 instruction set that is part of the AMD E86 family, which continually offers instruction-set-compatible upgrades. Built into the Am186CC controller is a wide range of communications features required in many communications applications, including High-level Data Link Control (HDLC) and the Universal Serial Bus (USB). AMD offers complete solutions with the Am186CC controller. A customer development platform board is available. Reference designs under development include a low-end router with Integrated Services Digital Network (ISDN), Ethernet, USB, Plain Old Telephone Service (POTS), and an ISDN Terminal Adapter featuring USB. AMD and its FusionE86SM Partners offer boards, schematics, drivers, protocol stacks, and routing software for these reference designs to enable fast time to market.
