JTAG PROBES FOR SIGNUM EMULATORS
TECHNICAL SPECIFICATIONS

ADA-ARM-SWD
The ARM-SWD probe supports both ARM and Cortex boards at voltages 0.8V to 5.0V. It must be used when
Cortex Serial Wire Debug or Cortex Serial Wire Output operation mode is required.
In addition to a standard 20-pin double-row female ARM connector, this probe has a 20-pin and 10-pin high-
density Cortex connectors. Only one connector can be used at a time. The ARM connector, mounted
underneath the probe, has the pinout of the ADA-JET-ARM20 probe (
Figure 12). The pinouts of the 20-pin
and 10-pin Cortex connectors are shown in Figure 13 and Figure 14, respectively. The two high-density cables
included with the probe provide a link between the Cortex connectors and the target board (Figure 11).

The mating JTAG headers for targets are shrouded with a key, but will require removal of one pin (
