Table V lists the pinout for the female connectors on the EZ-
ICE’s EB board. See the ADSP-2171 Data Sheet for TQFP pin
locations, footprint, and mechanical information.

Table VI lists the ADSP-2171’s emulator-only pins that
correspond to the EZ-ICE connector pins. These 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. These
pins have no function except during emulation. Keep all
connections as short as possible. The 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. The 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
TQFP DSP packages, one alternative does exist for the PQFP
target system. This 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 EZ-LAB and EZ-ICE Together
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. These combinations let you prototype and evaluate
your application without initial time investment in hardware
design.
