About the Am186

™

Microcontroller ISDN-to-Ethernet

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.
