Router Reference Design
The AMD Am186CC microcontroller ISDN-to-Ethernet router reference design
(hereafter referred to as the Am186CC microcontroller router reference design) is
used for customer development of ISDN and Ethernet interfaces, High-Speed
universal asynchronous receiver/transmitters (UARTs), USB ports, Flash memory,
and plain old telephone Service (POTS) circuitry. The board includes the
Am186CC microcontroller, Am79C961A PCnet
™
-ISA II 10BaseT Ethernet
controller, Am79C031 DSLAC
™
device, two Am79R79 ringing SLICs,
Am79C32A
ISDN S/T data controller, T7237A ISDN U data controller, and
Am29F800 Flash memory.
The Am186CC microcontroller router reference design consists of a single board
with an external power supply module. The block diagram is shown in Figure 0-1
on page xii.
The reference design provides a glueless interface to Flash memory, DRAM and
SRAM system main memory, communication interfaces such as a High-Speed
UART, universal serial bus (USB), and four HDLC channels.
Other features include a debug interface that allows connection to the optional test
interface port (TIP) debug board.
