An alternate approach is required for the T QFP chip package.
Because of the extremely low profile of the surface mount
T QFP package, it is not practical to use a snap-on adaptor or
probe. T hus, in order to use the EZ-ICE, it is necessary to
provide a pair of header connectors on the target board that the
ADDS-21xx EZ-ICE board can plug directly onto. Extra space
around the adaptor and extra through-holes to the PQFP
package are not required to let you use the same PCB in
production. Dimensional requirements for placing the headers
is also shown in Figure 2.
ADSP-2181
T here is no need for a surface mount adaptor for the ADSP-
2181 EZ-ICE. Instead, the ICE-Port Emulator Interface allows
for a simple 14-pin connector interface between the target board
and the EZ-ICE.

SY ST E M FOR T HE ADSP-2181 AND T HE ADSP-2171
ADSP-2181 T arget System Requirements
T he ADSP-2181 has on-chip emulation support and a special
set of pins that interface to the EZ-ICE called the ICE-Port.
T he ICE-Port allows in-circuit emulation without replacing the
target system’s processor or overriding it with a probe, requiring
only a simple 14-pin header connector to interface to the EZ-
ICE (see Figure 3).
T able IV lists the pins and functions used in the ADSP-2181’s
ICE-Port emulation interface.

all traces as short as possible; no longer than 3 inches.
GUI Interface
EZ-ICE software uses a Graphical User Interface (GUI) to
increase development productivity by making your data easier to
view and manipulate—without switching between screens—
when debugging. In addition, you can obtain on-line help for
the currently selected window. T he GUI user interface design is
the same one used with the ADSP-2100 Family Simulator
software, making both tools easier to use.
Clock Speed
EZ-ICE runs at full speed. T here is no degradation of
processor performance other than
BR

RESET

are slightly delayed. A jumper is used to select either the target
system clock or the EZ-ICE clock. T he oscillator socket lets you
use other oscillator devices to achieve different clock speeds.
Memory
T he ADSP-2101, ADSP-2111, and ADSP-2171 EZ-ICE each
have 8K

overlay data memory. You can either run programs from target
system memory, emulator overlay memory, or from a combination
of both. T he overlay memory option is jumper-selectable.
Additional E quipment Required
EZ-ICE requires a +5 V dc power supply capable of supplying
1 A of current.
3-Volt E mulation
T he 3-Volt Emulation Converter Board may be used with the
ADSP-2101 EZ-ICE to enable emulation of ADSP-2103 (3 V)
systems.
SURFACE MOUNT ADAPT ORS
ADSP-2101/ADSP-2105/ADSP-2115
Several surface mount adaptors are available for emulation of
the ADSP-2101. For example: for the 68-pin PLCC package of
the ADSP-2101 and ADSP-2105, a PGA-to-PLCC adaptor is
available from the vendors listed at the end of this data sheet.
For the 80-pin PQFP package of the ADSP-2101, a 68-pin
PGA to 80-pin PQFP adaptor is also available.
T he ADDS-2101-PGA/PQFP, a surface-mountable PGA-to-
PQFP adaptor, provides a footprint that exactly matches the 80-
pin package. T his solution does not require extra space around
the adaptor or an extra through hole to the PQFP package to let
you use the same PCB in production. T he PGA-to-PQFP
adaptor is surface mounted in the usual manner, and the PGA
connector of the ADSP-2101 EZ-ICE or ICE can be directly
plugged in.
ADSP-2111
T he ADDS-2100-PGA/PQFP, a surface-mountable 101-pin
PGA to 100-pin PQFP adaptor, matches the ADSP-2111
package footprints. T his solution does not require extra space
around the adaptor, and you can use the same PCB in
production. T he PGA-to-PQFP adaptor is surface mounted in
the usual manner, and the PGA connector of the ADSP-2111
EZ-ICE can be directly plugged in.
ADSP-2171
T he ADSP-2171 EZ-ICE Emulator is designed for compatibil-
ity with the surface mountable 128-pin PQFP package using an
adaptor card which plugs onto the ADDS-21xx EZ-ICE board
and then snaps onto the PQFP chip. T his is illustrated in Figure
3. Extra space should be allowed around the PQFP chip to
allow clearance for the adaptor.
