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.
