This design is intended to reduce the time to market for ISDN designers using the Am186CC communications controller. Figure 0-1 shows a block diagram of the ISDN TA reference design. The ISDN TA reference design is a fully functional ISDN TA that illustrates the benefits of using the Am186CC communications controller ISDN TA reference design. The Am186CC communications controller has a number of integrated features required in many communication applications. These features include four high-level data link controller (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™ controller channels, four time slot assigners (TSAs), UART, 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 kbps, or by using a full-speed USB connection at 12 Mbps. Note that the High-Speed UART is capable of 460 kbps, but is limited by the reference design’s UART transceiver, which is only capable of 230 kbps, and also by the PCs that the ISDN TA would connect because most of them are only capable of speeds up to 115 kbps or 230 kbps.

ISDN provides greater performance than analog and is still affordable to consumers. There are many different variations of ISDN available, but the most common is 128-kbps data transfer rate over two B (bearer) channels, plus 16 kbps 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 kbps. Broadband ISDN is available and can achieve data rates in the 100-Mbps range. There are a number of reference points in an ISDN system. Figure 0-2 shows a graphical representation of the ISDN reference points. 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 four-wire 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.

Refer to Figure 2-1 on page 2-4 for layout and component placement. The ISDN TA reference design board 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. Table 2-1.

ISDN TA Reference Design Circuit Board Layout 2-4 Am186TMCC Microcontroller ISDN TA Reference Design Manual about.book Page 5 Friday, December 18, 1998 9:41 AM 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. Am186CC Microcontroller The ISDN TA reference design is used to control the ISDN TA. A block diagram of the ISDN TA reference design is shown in Figure 2-2. The many integrated features of the Am186CC communications controller 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-Mbps PC interface. The HDLCs provide a glueless interface to either the S/T transceiver or the U transceiver. Figure 2-2. Am186CC Microcontroller ISDN TA Reference Design Block Diagram Am186TMCC Microcontroller ISDN TA Reference Design Manual 2-5 about.book Page 6 Friday, December 18, 1998 9:41 AM 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.

ISDN TA Clock Generation Circuit 2-6 Am186TMCC Microcontroller ISDN TA Reference Design Manual about.book Page 7 Friday, December 18, 1998 9:41 AM System Memory This design uses 512 Kbyte of AMD Flash memory for code space located from 0x80000h–0xFFFFFh, and 512 Kbyte of DRAM. The memory schematic is shown in Figure 2-4. 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 Kbyte of Flash memory is not sufficient, PIO 35 is routed to the chip to act as a bank select. This allows drop in compatibility for larger Flash memory, such as the 29F800 device.

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 ISDN TA reference design has an integrated DRAM controller that makes a glueless DRAM interface simple to use. The Am186CC communications controller DRAM interface allows zero-wait state operation at 48 MHz using a 40-ns DRAM. This DRAM device is located from 0x00000h–0x7FFFFFh in low memory space and is selected using LCS/RAS0.

This device has a general circuit interface (GCI) or 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 communications controller-based ISDN TA reference design provides a fullduplex 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-kbps B channels and a single 16-kbps D channel. The schematic for the S/T interface block is shown in Figure 2-5. 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 communications controller.

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 it’s integrated HDLC. This chip provides the two-wire network termination. It processes the ISDN BRI bit stream that consists of two 64kbps B channels and a single 16-kbps D channel. The schematic for the U interface block is shown in Figure 2-6. 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.

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 5.5-mm barrel connector. A Raychem 750-mA fuse is used to protect the circuit from any 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.

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 Am186TMCC Communications Controller Test Interface Port (TIP) User’s Manual for more information. Note that the TIP board and user’s manual are available from AMD, but are not included in your kit. The TIP connector circuit and pinout are shown in Figure 2-10.

The x8 boot is accomplished by using JP2 to pull the MCS0# signal to ground during reset (see Figure 2-11). 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. MCS0# TP_TERM JP2 1 2 HEADER 2 R38 10K 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 Z command, changing the jumpers to the settings for booting from the main board, then following the prompts from the Z command.
