• Small, complete, all-in-one JTAG programming/debugging solution for Xilinx FPGAs with UART side channel
• Compatible with Xilinx Tools
• High-Speed USB 2.0 port that can drive JTAG bus up to 30Mbit/sec (frequency settable by user)
• Open drain buffer on PS_SRST_B pin allows debugging software to reset the processor core of Xilinx’s Zynq® platform

The Joint Test Action Group (JTAG)-SMT3-NC is a compact, complete, and fully self-contained surface-mount programming module for Xilinx field-programmable gate arrays (FPGAs). The module can be accessed directly from all Xilinx Tools, including iMPACT, ChipScope™, Vivado, and EDK. Users can load the module directly onto a target board and reflow it like any other component.

The JTAG-SMT3-NC uses a 3.3V main power supply and independent Vref supplies to drive the JTAG and UART signals. All JTAG signals use high-speed 24mA three-state buffers that allow signal voltages from 1.8V to 5.5V, and bus speeds up to 30MBit/sec. All UART signals use high-speed 24mA buffers that allow signal voltages from 1.8V to 5.5V and bus speeds up to 12Mbaud. The JTAG bus can be shared with other devices as the SMT3-NC signals are held at high impedance, except when actively driven during programming. The SMT3-NC module is CE certified and fully compliant with EU RoHS and REACH directives. The module routes the USB D+ (DP) and D- (DM) signals out to pads, providing the system designer with the ability to choose the type of USB connector and its location on the system board.
