The Texas Instruments/Burr-Brown JTAG 3/5V Parallel Port JTAG Emulator is a hardware debugging tool for embedded systems development. It connects to a host PC via standard parallel port (SPP8, EPP, ECP) and interfaces with target systems through IEEE 1149.1 JTAG headers. The emulator supports both 3.3 V and 5 V JTAG signaling, making it suitable for diverse processor architectures across TI’s DSP and microcontroller portfolios.
Technical Specifications
• Host Interface: DB25 parallel port connector; supports SPP8, EPP, and ECP modes
• Target Interface: JTAG (IEEE 1149.1); 14-pin standard header plus support for TI 20-pin compact, 20-pin ARM, and 60-pin TI configurations via adapter boards
• TCK Frequency: Programmable up to 32 MHz
• JTAG Voltage Support: 3.3 V and 5 V signaling; target processor compatibility 1.8 V to 5 V
• Power Consumption: Up to 250 mA when powered by target system
• Emulation Controller: Advanced controller for high-performance debugging
• Boundary Scan: Programmable EMU0/EMU1 pins for Boundary Scan Test support; includes Wait-In-Reset features for TI DSP families (e.g., TMS27xx)
• Status Indicator: Single operational status LED
– Key Features
• Flexible dual-voltage JTAG support eliminates need for multiple tools across 3.3 V and 5 V target systems
• Multiple header configurations reduce adapter board requirements for common TI processor packages
• Programmable TCK frequency to 32 MHz enables optimization for target architecture timing constraints
• EMU0/EMU1 pin control supports both boundary scan testing and processor-specific wait-in-reset initialization sequences
– Typical Applications
• Development and debug of TI DSP systems (C2xx through C674x families)
• Firmware programming and real-time debugging on ARM-based and OMAP processors
• Hardware validation of DaVinci-based imaging platforms
• Boundary scan testing and in-circuit verification
