ARM Cortex Probe

ADA-ARM20-Cortex

This passive adapter allows you to interface any Signum JTAGjet emulator that uses the 20-pin JTAG probe

for ARM (ADA-JET-ARM20 or its low-voltage variant ADA-JET-ARM20-LV) with a Cortext-M target board.

Both 20-pin and 10-pin high-density Cortex connectors are supported, but only one of them can be used at a

time. The ARM connector of the probe has the pinout of the ADA-JET-ARM20 probe (Figure 2). The pinouts

of the 20-pin and 10-pin Cortex connectors are shown in Figure 13 and Figure 14 (page 5), respectively.

FIGURE 16 The dimensions of the ADA-ARM20-SWD probe. C = 23.6 mm (0.93 in),

D = 3.11 mm (0.122 in), H = 5.1 mm (0.2 in), L = 69.3 mm (2.73 in), W = 15.73 (0.62

in), W1 = 10.5 mm (0.41 in), W2 = 16.9 mm (0.67).

The mating JTAG headers for targets are the same as those for the ADA-ARM-SWD probe (Table 4 on page

).
