In-Circuit Emulator Support
Because pins are an expensive resource, many play a
dual role, and the programmer selects PIO operation or
an alternate function. However, a pin configured to be
a PIO may also be required for emulation support.
Therefore, it is impor tant that before a design is
committed to hardware, a user should contact potential
emulator suppliers for a list of their emulator’s pin

multiplexed with alternate signals that may be used by
emulators: PIO8, PIO15, PIO33–PIO35.
APPLICATIONS
The Am186CC microcontroller, with its integrated
HDLC, USB, and other communications features,
provides a highly integrated, cost-effective solution for
a wide range of telecommunications and networking
applications.

generation ISDN equipment requires USB (or High-
Speed UART capability), in addition to three
channels of HDLC.
sonal routers, often used for connections in Small
Office/Home Office (SOHO) environments, require
three channels of HDLC, as well as the high perfor-
mance of a 16-bit controller.
Central Offices (COs), PABX equipment, and other
telephony applications require one or two channels
of HDLC. Linecard manufacturers are moving to
more lines per card for analog POTS as a means of
cost reduction. This, and digital linecards for sup-
port of ISDN, often require higher performance than
existing 8-bit devices can offer. The Am186CC mi-
crocontroller is an ideal solution for these applica-
tions because it integrates much of the necessary
glue logic while providing higher performance.

handling of 2 Mbit/s or greater and can take advan-
tage of the USB interface for easy connectivity to

tions.

ket. These applications often require a robust, high-
performance processor solution with one or two
channels of HDLC.
Am186™CC Communications Controller Data Sheet
The Am186CC microcontroller was designed to
minimize conflicts. In most cases, pin conflict is
avoided. For example, if the ALE signal is required for

programmed as PIO33. If the multiplexed AD bus is not
used, then ALE can be programmed as a PIO pin. If the
multiplexed bus is not in use, then the emulator does
not require the ALE signal. However, an emulator is
likely to always use the de-multiplexed address,
regardless of how the AD bus is programmed.

Block diagrams on the following pages show some
typical Am186CC microcontroller designs: Figure 5 on
page 38 shows an ISDN terminal adapter system
application, Figure 6 on page 38 shows an ISDN to
Ethernet low-end router application, and Figure 7 on
page 39 shows a 32-channel linecard application.
The ISDN ter minal adapter features an S/T or
U interface and either a High-Speed UART or USB
connection for attaching the modem to the PC.
The ISDN-to-Ethernet low-end router features an S/T
or U interface, two POTS lines, and a 10-Mbit/s
connection to the PC.
The 32-channel linecard design demonstrates the
Am186CC microcontroller’s us e in a linecard
application where 32 incoming POTS lines are
aggregated onto a single E1 connection.
come more common as the PC market embraces
the USB protocol. In addition to implementing com-
munications device class systems such as an ISDN
terminal adapter, the USB controller makes the
Am186CC microcontroller suitable for certain PC
desktop applications such as a USB camera inter-
face, ink-jet printers, and scanners.
Am186CC microcontroller will also find a home in
general embedded applications, because many de-
vices will incorporate communications capability in
the future. Many designs are adding HDLC capabil-
ity as a robust means of inter- and intra-system
communications. The Am186CC microcontroller is
especially attractive for 186 designs adding HDLC,
USB, or both.
