About the Am186™CC/CH/CU
Microcontroller Customer
Development Platform
The AMDAm186™CC/CH/CU microcontroller customer development platform
(CDP) is a system used for customer evaluation and development for the
Am186CC/CH/CU microcontrollers. The platform provides access to the major
microcontroller interfaces and is an ideal tool for developing customer-specific
applications by using the development module interface.
The CDP consists of two boards—a main board that contains the Am186CC
communications controller and interfaces (shown in Figure 0-1), and the
development module, which can be used for the development of various
communicationsapplicationssuchasISDNTAsandrouters(showninFigure0-2).
The main board consists of a power supply that provides the necessary voltages
for typical system applications of the Am186CC/CH/CU microcontroller. The
main board also provides a glueless interface to Flash memory and DRAM or
SRAM system main memory, communication interfaces such as a universal
asynchronousreceiver/transmitter(UART)andHigh-SpeedUART,universalserial
bus (USB), and four synchronous serial DCE connections. Other features include
the debug interfaces that allow connection to the following:
• ROM-ICE
• Optional Test Interface Port (TIP) debug board
• HP logic analyzer headers to provide access to the Am186CC communications
controller signals
• Expansion interface through the development module or the 104-pin Am186
processor expansion interface

The development module consists of an Am79C961A PCnet™-ISA II Ethernet
Controller for 10BaseT Ethernet, an Am79C32A ISDN digital subscriber
controller (DSC) circuit for an ISDN S/T connection, an ISDN U connection, and
two POTS connections featuring the Am79C031 DSLAC™ device and two
Am79R79 Ringing SLICs.
NOTE: Although the customer development board provides an Am186CC
microcontroller, you can also use the board to develop Am186CH HDLC
microcontroller applications and Am186CU USB microcontroller applications.
TheAm186CHandAm186CUmicrocontrollerssupportsubsetsof theAm186CC
microcontroller features. The Am186CH HDLC microcontroller provides two
HDLC channels and does not support USB or GCI. The Am186CU USB
microcontroller does not support HDLC.
