TSC21020F
4153H–AERO–04/07
A low frequency bypass capacitor (20 F tantalum) located near the junction of the
IVDD and EVDD traces is also recommended.
Target System
Requirements for Use of
EZ-ICE Emulator
The ADSP-21020 EZ-ICE uses the IEEE 1149.1 JTAG test access port of the
TSC21020F to monitor and control the target board processor during emulation. The
EZ-ICE probe requires that CLKIN, TMS, TCK, TRST, TDI, TDO, and GND be made
accessible on the target system via a 12-pin connector (pin strip header) such as that
shown in Figure 20. The EZ-ICE probe plugs directly onto this connector for chip-on-
board emulation; you must add this connector to your target board design if you intend
to use the ADSP-21020 EZ-ICE. Figure 21 shows the dimensions of the EZ-ICE probe;
be sure to allow enough space in your system to fit the probe onto the 12-pin connector.

The 12-pin, 2-row pin strip header is keyed at the Pin 1 location - you must clip Pin 1 off
of the header. The pins must be 0.025 inch square and at least 0.20 inch in length. Pin
spacing is 0.1 x 0.1 inches.
