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.

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.
