A customer development platform board is product family. The Am186CC controller is a cost- available. Reference designs under development effective, high-performance microcontroller solution for include a low-end router with Integrated Services communications applications. This highly integrated Digital Network (ISDN), Ethernet, USB, Plain Old microcontroller enables customers to save system Telephone Service (POTS), and an ISDN Terminal SM costs and increase performance over 8-bit Adapter featuring USB. AMD and its FusionE86 microcontrollers and other 16-bit microcontrollers. Partners offer boards, schematics, drivers, protocol stacks, and routing software for these reference The Am186CC communications controller offers the designs to enable fast time to market. advantages of the x86 development environments 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).
