CC Microcontroller ISDN TA Reference Design Manual
2-5
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.
