Do not connect a separate power supply to your EZ-ICE board
when it is inserted in your prototype through the emulator
connectors. T he power connectors on the EZ-ICE EB board
are for stand-alone operation only.
(Note: For use in a stand-alone mode, a DSP target card is
supplied with the EZ-ICE and plugs onto the EZ-ICE through
the same pair of connectors described above.)
Also, while this scheme may be used for either the PQFP or
T QFP DSP packages, one alternative does exist for the PQFP
target system. T his alternative involves a snap on PQFP
adaptor, also shown in Figure 1, that plugs onto the EZ-ICE EB
board and snaps onto the DSP chip.
Using E Z-LAB and E Z-ICE T ogether
Combining an EZ-LAB with an EZ-ICE forms a high speed
DSP evaluation and development environment with an
interactive, window-based debugging interface. For the ADSP-
2101 and ADSP-2111 EZ-LAB/EZ-ICE combinations, remove
the processor device from its socket on the EZ-LAB board and
plug the EZ-ICE into the DSP’s empty socket. For the ADSP-
2171 EZ-LAB/EZ-ICE combination, simply snap the EZ-ICE
with its PQFP adaptor onto the EZ-LAB’s processor. And for
the ADSP-2181 EZ-LAB/EZ-ICE combination, simply plug the
EZ-ICE’s ribbon cable connector onto the EZ-LAB’s ICE-Port
connector. T hese combinations let you prototype and evaluate
your application without initial time investment in hardware
design.
T able V lists the pinout for the female connectors on the EZ-
ICE’s EB board. See the ADSP-2171 Data Sheet for T QFP pin
locations, footprint, and mechanical information.

T able VI lists the ADSP-2171’s emulator-only pins that
correspond to the EZ-ICE connector pins. T hese emulator-
only pins are listed on the ADSP-2171 data sheet as no-
connects (NC). Also, note that the emulator-only pins must be
connected only from the DSP to the emulator connector. T hese
pins have no function except during emulation. K eep all
connections as short as possible. T he scheme of mounting the
connectors on opposite sides of the DSP is best.
Do not connect a separate power supply to your EZ-ICE board
when it is inserted in your prototype through the emulator
connectors. T he power connectors on the EZ-ICE EB board
are for stand-alone operation only.
(Note: For use in a stand-alone mode, a DSP target card is
supplied with the EZ-ICE and plugs onto the EZ-ICE through
the same pair of connectors described above.)
Also, while this scheme may be used for either the PQFP or
T QFP DSP packages, one alternative does exist for the PQFP
target system. T his alternative involves a snap on PQFP
adaptor, also shown in Figure 1, that plugs onto the EZ-ICE EB
board and snaps onto the DSP chip
