GENERAL DESCRIPTION  
The Am186™CU USB microcontroller is a member of  
AMD’s Comm86™ family of communications-specific  
microcontrollers. The microcontroller is a derivative of  
the Am186CC communications controller and is pin-  
compatible with that device.  
Built into the Am186CU USB microcontroller is a wide  
range of communications features required in many  
communications applications, including the Universal  
Serial Bus (USB) peripheral controller that designers  
can use to implement a variety of microcontroller-  
based USB peripheral devices for telephony, audio, or  
other high-end applications. The USB controller does  
not support USB host or hub functions, but the  
Am186CU USB microcontroller can be used to  
implement USB peripheral functions in a device that  
also contains separate USB hub circuitry.  
The Am186CU USB microcontroller is a cost-effective,  
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.  
Comprehensive development support is available from  
AMD and its FusionE86SM partners. A customer  
development platform board is available. AMD and its  
FusionE86 partners also offer boards, schematics,  
drivers, protocol stacks, and routing software to enable  
fast time to market.  
The microcontroller offers the advantages of the x86  
development environment’s widely available native  
development tools, applications, and system software.  
Additionally, the microcontroller uses the industry-  
standard 186 instruction set that is part of the AMD  
E86™ family, which continually offers instruction-set-  
compatible upgrades.
