JTAG PROBES FOR SI GNUM T E C H N I C A L EM ULATORS S P E C I F I C A T I O N S JTAG TMS320 Isolation Probe ADA-ISO-TI14 The JTAG Isolation Probe for TMS320/470/570 Devices from Texas Instruments is a full isolation JTAG probe for JTAGjet emulators which reduces the chance of damage to the emulator associated with ground loops, voltage spikes, electrostatic discharge (ESD) and noise on power and ground lines generated by highcurrent motors and other machinery. The probe fits between the JTAGjet emulator and the user’s target board equipped with the Texas Instruments style 14-pin JTAG connector. The distinctive features of the ADA-ISO-TI14 include • Support for all TMS320C2000, C5000, C6000, OMAP, DM and TMS470 / 570 devices • Operating JTAG voltage from 3.0 V to 5.0 V (± 10%) Galvanic isolation up to 1000 V (peak)* 50kV/µs transient immunity (typical) on JTAG lines ESD protection of 8kV on contact and 15kV air discharge Maximum JTAG clock rate up to 15MHz • • • • Important Notice The continuous normal operating voltage across the isolation barrier can be 0 – 60VDC. The isolation voltage only represents a measure of immunity to transient voltages—the probe should never be used as an element of a safety isolation system. This probe can be expected to function correctly with a few hundred volts offset applied continuously across the isolation barrier. However, the circuitry on both sides of the barrier is then regarded as operating at an unsafe voltage and additional isolation/insulation systems must be used in accordance with safety standard requirements. * Signum Systems shall not be liable for any damages related to the use of this probe.

JTAG PROBES FOR SI GNUM T E C H N I C A L EM ULATORS S P E C I F I C A T I O N S Isolation Probe for TI-14 JTAG with an Optional External Power Input ADA-ISO-TI14-E The isolation probe for TI-14 JTAG with an auxiliary power input ADA-ISO-TI14-E should be used in applications where the target board does not have enough current (about 150mA) to supply the isolation probe. When used with external power adapter, this probe reduces the current taken from the target board to approximately 1 mA. The ADA-ISO-TI14-E probe requires a 5.0V VDC external power source to be connected to the J1 socket. The polarity for the J1 socket is center pin positive (+), outer collar negative (−). Reversed polarity may damage some electronic devices. If the external power supply is not connected, the isolation probe will automatically take power (about 150mA) from the target board. The auxiliary power adapter is not included with the isolation probe. See also the specification of the ADA-ISO.

This probe has 20-pin receptacles. The pin-topin X spacing is 0.10 in., Y spacing 0.05 in. The female connector on the probe is SAMTEC RSM-110-02-S-D. This is a low votage probe operating in the 1.8 – 3.3V (± 10%) range. Figure 30 shows the probe’s pinout. Pin 1 FIGURE 29 The ADA-JET-CTI20 probe for the Signum JTAGjet-eBinder emulator.

Note 1 Note 2 Note 3 Note 4 Set the SW1-4 switches only when the emulator and the target are not powered! Do not set SW1-2 and SW3-4 pairs both ON. The setting will short the EMU0, EMU1 and nSYSRTS lines on the target. The nSYSRTS, EMU0 and EMU1 lines are bi-directional and are driven by an opencollector gate in the emulator. EMU0 and EMU1 have 100K pull-ups to the PD pin on the probe side, while nSYSRST has 220K pull-up to the PD pin. Certain JTAGjet driver packages may not easily allow configuring EMU0 and EMU1 as nSYSRST. Therefore it is recommended to leave the DIP switch in its default position. The software is unable determine the position of this switch automatically. When SW2 or SW4 are ON, the software needs to be configured accordingly. Sample settings that allow EMU0 to act as a CPU reset signal (nSYSRST) are shown in Figure 34. FIGURE 34 Configuring the JTAGjet-eBinder driver to use the EMU0 signal as the CPU reset signal (EmuDiag for the JTAGjet-eBinder). All future releases of the JTAGjet software will allow the user to redefine the EMU0 and EMU1 pins as CPU reset pins. 13 SI GNUM SYSTEM S ETM Connector for ARM & OMAP The JTAGjet-Trace series emulators come with an Embedded Trace Macrocell (ETM) cable terminated with a 38-pin Mictor connector.

Some boards, however, separate the two types of signals, providing two different connectors for them. These boards require a JTAG-ETM splitter probe, ADA-ETM-JTAG.

The probe’s ETM connector has the pinout of ETM connector when used with ARM targets (Figure 42). 38-pin ETM Connector L A W1 W B H Ribbon Cable Pin 1 FIGURE 39 The ADA-ETM-SWD20 probe for Cortex boards with ETM trace.

JTAG PROBES FOR SI GNUM T E C H N I C A L EM ULATORS S P E C I F I C A T I O N S Active 12-pin MPSD Probe ADA-JET-MPSD The Signum MPSD (modular port scan device) probe ADA-JET-MPSD provides a physical interface between JTAGjet emulators for the TMS320 3x family of DSPs and target boards. The probe has 12 double-row, polarized, 2.54 mm × 2.54 mm (.100" × .100") receptacles (female connectors). To ensure proper orientation, the header is keyed. The ADA-JET-MPSD is a 5V Texas Instruments MPSD legacy adapter designed specifically for the Signum JTAGjet-C3x in-circuit emulator. It allows emulation at a maximum speed of 60 MHz. For the pinout, see Figure 44. EMU1 1 2 GND EMU0 3 4 GND TDO / EMU2 5 6 GND VCC 7 8 KEY (no pin) TDI / EMU3 9 10 GND 11 12 GND TCK / H3 Pin 1 FIGURE 43 The ADA-JET-MPSD probe for TMS320 3x DSPs.
