EZ-ICE EMULATORS: SPECIAL CONSIDERATIONS
Connector Requirements
The PGA probe’s footprint that protrudes from the bottom of
the ADSP-2101 and ADSP-2111 EZ-ICE boards fits into the
DSP chip socket on your target system. Note that the socket
must allow sufficient clearance for the ADSP-21xx’s footprint.

TARGET BOARD
CUSTOMER
The ADSP-2171 EZ-ICE attaches to the target DSP chip by
simply clipping over the PQFP package version of the DSP. An
alternate approach is needed for use with the TQFP package
version of the DSP. Because the TQFP packaged chip and its
leads are too small for a probe, the target board should include a
pair of header connectors to allow the EZ-ICE board to plug
directly onto it in order to interface with the DSP chip. Both
methods are illustrated in Figure 2.
