About the Am186™CC
Microcontroller ISDN TA
Reference Design
The Am186CC microcontroller ISDN terminal adapter (TA) reference design is a
small, cost-effective ISDN solution for embedded communications applications.
This design is intended to reduce the time to market for ISDN designers using the
Am186CC microcontroller. Figure 0-1 shows a block diagram of the ISDN TA
reference design.
The ISDN TA reference design is a functional ISDN TA that illustrates the benefits
of using the Am186CC microcontroller. The Am186CC microcontroller has a
number of integrated features required in many communication applications. These
features include four high-level data link control (HDLC) channels and a universal
serial bus (USB) peripheral controller with an internal transceiver. The HDLC
channels support GCI/IOM-2, PCM, and DCE interfaces. Other integrated features
include four general-purpose DMA channels, eight SmartDMA™ channels, four
time-slot assigners (TSAs), one UART, one High-Speed UART with autobaud, and
an integrated DRAM controller.
The ISDN TA reference design illustrates how to use many of the integrated
peripherals to provide a small, low-cost ISDN TA. The reference design supports
either an ISDN 2B+D U or S/T network interface by a component population
option. You can interface to a PC using either the High-Speed UART connection
at up to 230 Kbit/s, or by using a full-speed USB connection at 12 Mbit/s.
Note that the ISDN data rate is 128 Kbit/s, so the reference design’s UART
transceiver is only 230 Kbit/s. This limits the High-Speed UART, which is actually
capable of 460 Kbit/s. The PCs that the ISDN TA would connect are also a limiting
factor because most are only capable of speeds up to 115 Kbit/s or 230 Kbit/s.

ISDN Background
ISDN (integrated services digital network) is an alternative to analog phone lines.
ISDN provides greater performance than analog and is still affordable to
consumers. There are many different variations of ISDN available, but the most
common variation is 128-Kbit/s data transfer rate over two B (bearer) channels,
plus 16 Kbit/s of signaling data over the D channel; this is the 2B+D configuration,
the configuration used by the ISDN TA reference design discussed in this manual.
Another configuration uses a single B channel and transfers data at 64 Kbit/s.
Broadband ISDN is available and can achieve data rates in the 100-Mbit/s range.
There are a number of reference points in an ISDN system. Figure 0-2 shows a
graphical representation of the ISDN reference points. For more information about
Figure 0-2, refer to Digital Telephony, Second Edition, ISBN 0-471-62056-4.
The U reference point is the local loop between the LE (local exchange) and the
NT (network termination) device. The U interface is a two-wire interface, which
in North America and Asia is typically supplied by a telecommunications service
provider. The U interface operates in 2B1Q (two binary, one quaternary) format,
and can travel for miles without repeaters. The T reference point is used only with
customer premises switching equipment (NT2). The S/T reference point is the fourwire interface between the network termination device (NT1) and the terminal
equipment (TE1) or terminal adapter (TA). The S/T interface is offered in Europe,
and is also used with stand-alone NT1 devices.

Layout and Placement
The ISDN TA reference design emphasizes the small board size that can be obtained
by using the Am186CC microcontroller in an embedded communications
application. Refer to Figure 2-1 on page 2-4 for layout and component placement.
The ISDN TA reference design has the Flash memory, DRAM, and TIP connector
located close to the processor to provide a linear, logical signal flow for the address
and data bus. The connectors and the power switch are located at the back of the
board, and the status indicator LEDs are located at the front of the board. This
placement makes it possible to manufacture the board in a small enclosure. The
ISDN interface devices are overlapped where possible to minimize board size. In
Table 2-1, all of the parts are identified by part number and part description.
The ISDN TA reference design was designed to fit in a very small desktop
enclosure. The circuit board is 3.85” x 4.75”, and fits into a variety of enclosures.
There are mounting holes on three corners; the fourth is on the side.

Am186™CC Microcontroller
The Am186CC microcontroller is used to control the ISDN TA. A block diagram
of the Am186CC microcontroller is shown in Figure 2-2. The many integrated
features of the Am186CC microcontroller make it ideal for an ISDN application.
The integrated DRAM controller allows a glueless interface to the system memory.
You can use the built-in High-Speed UART with autobaud to communicate with
the PC. You can also use the full-speed USB peripheral controller with built-in
transceiver for a 12-Mbit/s PC interface. The HDLCs provide a glueless interface
to either the S/T transceiver or the U transceiver.

The system uses a single 24-MHz crystal. This design uses an internal 2x PLL,
which provides a 48-MHz system clock and the required 48-MHz USB clock.
Because the USB clock is derived from the system PLL, the USB crystal input,
USBX1, is terminated. The clock generation circuit is shown in Figure 2-3 and
sheet 6 of the schematics included in your kit.

System Memory
This design uses 512 kbytes of AMD Flash memory for code space located from
80000h–FFFFFh, and 512 kbytes of DRAM. The memory schematic is shown in
Figure 2-4 and sheet 3 of the schematics included in your kit. The Am29F400 Flash
memory is used in a 256K x 16 configuration. The Am29F400 is byte/word
selectable using the BYTE# pin. In case the 512 Kbytes of Flash memory are not
sufficient, PIO35 is routed to the chip to act as a bank select. This allows drop-in
compatibility for larger Flash memory, such as the Am29F800 device.

Figure 2-4. ISDN TA System Memory
DRAM was chosen over SRAM as main memory in this application because
DRAM is more cost effective than SRAM and because the Am186CC
microcontroller has an integrated DRAM controller that makes a glueless DRAM
interface simple to use. The Am186CC microcontroller DRAM interface allows
zero-wait state operation at 48 MHz using a 40-ns DRAM. This DRAM device is
located from 00000h–7FFFFFh in low memory space and is selected using LCS#/
RAS0#.

ISDN S/T Interface
The Am79C32A ISDN data controller (IDC) circuit is used to provide the fourwire 2B+D S/T interface. This device has a general circuit interface (GCI), also
referred to as IOM-2, serial microprocessor interface, which is used to transfer B
channel data to and from the Am186CC microcontroller’s integrated HDLC
controller. The Am186CC microcontroller-based ISDN TA reference design
provides a full-duplex path between the terminal equipment (TE) and the network
termination (NT) device. The controller processes the ISDN basic rate interface
(BRI) bit stream, which consists of two 64-Kbit/s B channels and a single 16-Kbit/
s D channel. The schematic for the S/T interface block is shown in Figure 2-5 and
sheet 4 of the schematics included in your kit.
The Am79C32A IDC circuit includes a D-channel HDLC controller which is used
by software to send and receive data on the D channel.
The four-wire ISDN S/T interface is first directed through an S transformer and
line filtering devices. These isolate and protect the modem from the outside lines.
The crystal is used to generate MCLK, which can be used as a master clock output
and as the system clock for the microprocessor.
The signals SBIN, SBOUT, SCLK, SFS, and BCL/CH2STRB can be configured
for serial bus port (SBP) or GCI. SBP is used by the current terminal adapter
software and is connected to HDLC Channel A on the Am186CC microcontroller.

ISDN U Interface
The Lucent T7237 circuit is used to provide the two-wire 2B+D U interface. This
device has a PCM serial microprocessor interface and an SSI (synchronous serial
interface). These interfaces are used to transfer data to and from the Am186CC
microcontroller using its integrated HDLC. This chip provides the two-wire
network termination. It processes the ISDN BRI bit stream that consists of two
64-Kbit/s B channels and a single 16-Kbit/s D channel. The schematic for the
U interface block is shown in Figure 2-6 and sheet 4 of the schematics included in
your kit. The U-interface circuit includes a line fuse, U transformer, DC termination
IC, and opto-isolation circuitry. The LED shown in Figure 2-6 is used to indicate
device status. The four states of the LED are Low, High, 1 Hz, and 8 Hz. Refer to
the Lucent T7237 device data sheet for a complete description.
The U-interface data is in 2B1Q format, which provides a four-level (quaternary)
amplitude modulation. A single quaternary symbol represents two binary bits. The
quaternary symbols are ± 3, ± 1, which represent 00, 01, 10, and 11 in binary.

Serial PC Interface
The serial port may be used for communication with a PC. The Sipex high-speed
RS-232 transceiver is used to provide serial data rates up to 230 Kbit/s. The DCE
serial connection is made through a standard female DB-9, which uses a straightthrough serial cable. PIO1 and PIO28 are used to provide extra flow control
signaling to support Plug and Play (PnP) operation. The two LEDs are used to
indicate transmit and receive activity. The schematic for the serial interface is
shown in Figure 2-7 and sheet 5 of the schematics included in your kit.

USB PC Interface
The ISDN TA reference design has an integrated USB peripheral controller with
a built in transceiver; differential USB signals connect directly to the controller
without requiring an external transceiver. A USB type-B connector is used for
connection to a PC. The N MOSFETs are used with the two PIOs for VCC attach
and detach. The attach and detach steps are listed below. The USB interface
transfers data at up to 12 Mbit/s. The schematic for the USB interface is shown in
Figure 2-8 and sheet 5 of the schematics included in your kit.
Attach
1. Am186CC microcontroller polls USB_Detect (PIO42) for logic High to detect
when an active host USB port is connected.
2. Am186CC microcontroller drives USB_VCC (PIO43) High to enable Q1 and
pulls up the USBD+ line to indicate to the host that this is a full-speed device.
Detach
1. Am186CC microcontroller polls USB_Detect for logic Low to detect a
disconnect of the host.
2. Am186CC microcontroller three-states USBD± in response to a disconnect.
3. Am186CC microcontroller removes USB_VCC to disable Q1; Q2 isolates
USB_Detect in response to a disconnect.

Power Supply
This design requires only two voltages, +5 V and +3.3 V. The associated currents
and power estimates are included in Table 2-2. A 5-V, 500-mA, regulated, wallmount AC adapter is used to supply system power. The AC adapter is connected
to the system using a standard 2.5-mm barrel connector. A Raychem 750-mA fuse
is used to protect the circuit from a surge in current. To reset the fuse, unplug the
board and allow the fuse to cool. Most of the devices on the board require 5 V. The
5 V is used directly from the regulated supply. The Am186CC microcontroller and
the inverter chip are the only 3.3-V devices on this board. The 3.3 V is obtained
from the LDO (Low Drop Out) linear regulator. The power supply and reset
schematics are shown in Figure 2-9 and sheet 6 of the schematics included in your
kit.

Test Interface Port (TIP)
The test interface port (also available from AMD, but not included with the ISDN
TA reference design) provides an interface to a low-cost AMD development board.
This board is useful for testing, debugging, and developing software on AMD’s
reference designs. It contains an 8-bit Flash memory device, LEDs, hexadecimal
displays, an LCD, serial ports, a parallel port, and an Ethernet controller.
In the event of a Flash memory failure on the main board, you can boot the ISDN
TA from an external TIP board. Refer to the AMD Test Interface Port Board User’s
Manual, order #22505 for more information. Note that the TIP board and user’s
manual are available from AMD, but are not included in your kit. To order the TIP
board kit, contact your local AMD sales office at the number listed on the inside
back cover of this manual. The TIP connector circuit and pinout are shown in
Figure 2-10 and sheet 6 of the schematics included in your kit.

To boot from the TIP board, the Am186CC microcontroller must be reset in x8
boot mode, and the UCS# signal must be routed to the TIP Flash memory. The x8
boot is accomplished by using JP2 to pull the MCS0# signal to ground during reset
(see Figure 2-11 and sheet 6 of the schematics included in your kit). To route the
UCS# signal to the TIP Flash memory, remove the jumper on JP1 and install the
jumper on the TIP. When booting from the on-board Flash memory, use only JP1;
this routes UCS# to the ISDN TA Flash memory.

.
Figure 2-11. Flash Memory Jumper for x8 Boot (JP2)
To boot from the TIP Flash memory, perform the following:
• Disconnect UCS# from on board Flash memory (remove JP1).
• Route UCS# to the TIP Flash memory (install UCS# jumper on TIP).
• Boot in x8 mode (install JP2).
To boot from on-board Flash memory, perform the following:
• Route UCS# to the on-board Flash memory (install JP1).
• Boot in x16 mode (remove JP2).
A corrupted Flash memory on the main board can be restored by booting from the
TIP board, entering the E86MON software Z command, changing the jumpers to
the settings for booting from the main board, then following the prompts from the
Z command.

RESCON Configuration
The RESCON register provides a way to make design-specific hardware
configuration information available to software. The RESCON register is read
from AD0–AD15 during reset. Because the Am186CC microcontroller has weak
internal pulldowns, the default value is logic Low. Setting a bit requires a 10-kΩ
pullup resistor. Figure 2-12 shows the RESCON register bits.
