JTAG Isolation Adapter for ARM to protect Equipment

Blackhawk ARM04 October 2019 – Blackhawk introduce some time ago a USB JTAG Emulator for Texas Instruments DSP’s and now announced the BH-ADP-ISOARM an JTAG Isolation Adapter for ARM. The Blackhawk JTAG Isolation Adapter is a board that connects between the JTAG emulator and the JTAG connection of the target board. The adapter is designed to minimize and protect connected devices (PC/ Emulator/Target) from ground loop voltage, harsh environments and new, untested designs.

The adapter is very flexible by providing three JTAG connection options (Std. 20-pin ARM, 10 and 20-pin ARM Cortex) on both emulator and target sides. This also allows the adapter to be used as a converter from one JTAG connection type to another.

Features

  • Supports I/O voltages of 1.8V-5.0V targets
  • Serial wire debug (SWD) and IEEE 1149.1 (JTAG) protocols supported
  • High electromagnetic immunity
  • High-Speed operation: up to 24MHz TCK
  • Connections: ARM Std 20-pin, ARM Cortex 10 & 20-pin
  • Voltage Isolation: 5K Vrms
  • Powered by USB, Target VCC or Emulator
  • Current consumption is 20-80mA (varies with I/O voltage level and SW3 setting)
  • RoHS Compliant

The signal interface supports both standard JTAG (1149.1) and serial wire debug (SWD) protocols, eliminating the need to purchase two different isolators. The emulator and target sides of the adapter are powered from the target side VCC signals; however, the emulator side can be powered from USB or JTAG Emulator connectors with SW3 off to reduce power draw from the target should it be necessary. These features in addition to the high electromagnetic immunity, make this adapter a very versatile solution to protect equipment.

What’s Included

  • Isolation Adapter PC Board
  • 20-pin Ribbon Cable (0.100” x0.100”)
  • 10-pin Ribbon Cable (0.050” x 0.050”)
  • Bump-ons (4)
  • Quick Start Guide
  • Warranty and Product Registration Information
