The JTAG Technologies PM3705 Explorer is a high-performance boundary-scan controller engineered for structural board testing and in-system programming of programmable logic devices and flash memories. This self-contained desktop unit connects via PC parallel port and operates at 150 kHz, delivering two synchronized TAP output channels for simultaneous independent chain testing.
## Technical Specifications
The PM3705 Explorer targets 5V operation and maintains full compliance with IEEE 1149.1, IEEE 1149.6, IEEE 1149.4, and IEEE 1532 standards. The dual TAP channels enable parallel test execution across multiple boundary-scan chains with synchronized control for coordinated test pattern application.
## Key Features
• Two parallel TAP output channels for simultaneous driving and observation of independent boundary-scan chains
• PC parallel port host interface operating at the inherent speed of 150 kHz
• TAP channel synchronization for coordinated multi-device testing
• Support for in-system programming (ISP) of (C)PLDs and flash memories
• Structural boundary-scan testing capability
• Connectorized form factor designed for portable bench-top deployment
## Typical Applications
The PM3705 Explorer is suited to engineering environments and low-volume production scenarios requiring board-level functional and structural test coverage. Primary use cases include PLD programming, flash memory programming, and comprehensive JTAG-based circuit validation during prototype development and small-batch manufacturing.
## Compatibility & Integration
The controller integrates with JTAG Technologies developer tools, including JTAG ProVision and JTAG Live software platforms. The parallel port interface and standards-compliant TAP implementation enable integration into existing JTAG test infrastructures without requiring specialized host adapters or protocol converters.
