Overview

About Digilent JTAG-HS3 Programming Cable

Digilent JTAG-HS3 high-speed USB JTAG programming cable for AMD Xilinx FPGAs and Zynq SoCs, buy in India from GSAS

The Digilent JTAG-HS3 Programming Cable is an affordable high-speed USB programming solution for AMD (formerly Xilinx) FPGAs. Building on the successful JTAG-HS1, the HS3 adds an open-drain buffer on pin 14 that lets debugging software reset the processor core of AMD’s Zynq SoC platform, making it the budget-friendly choice for Zynq-7000 bring-up and debug. It works with any target voltage from 1.8 V to 5 V, runs at up to 30 Mbit/s with a user-adjustable frequency, and connects over a High-Speed USB 2.0 Micro-B port using AMD’s 2x7 2 mm JTAG connector.

How Engineers Use the JTAG-HS3

The JTAG-HS3 is the go-to external programmer when a project centers on AMD Zynq-7000 SoC hardware and needs processor-system (PS) reset control during debug. Its pin-14 open-drain buffer asserts PS_SRST_B so Vivado’s debug tools can reset the Arm core cleanly between sessions, essential for repeatable Zynq software bring-up. The slim form factor and AMD 2x7 connector make it ideal for compact custom boards, while the user-adjustable clock keeps programming reliable on long or loaded chains. R&D teams keep an HS3 on the bench for Vivado and iMPACT sessions; the cable also drops onto Zynq development boards that expose the standard AMD 2x7 JTAG header.

Vivado, ISE, and the Digilent Ecosystem

The JTAG-HS3 supports AMD ISE 14.1 and newer and Vivado 2013.3 and newer, alongside iMPACT, ChipScope, and EDK. For teams building on Digilent Zynq SoC boards such as the Zybo Z7, Eclypse Z7, or the Genesys ZU, the HS3 provides external programming and Zynq PS reset debug as an alternative to the on-board programmer. For Artix-7 boards without Zynq, the JTAG-HS2 is the more flexible companion cable.

GSAS Micro Systems is the authorized Digilent engineering partner in India, supplying the JTAG-HS3 with INR invoicing and FPGA and Zynq bring-up support for engineering teams across Bengaluru, Chennai, Hyderabad, Delhi NCR, Mumbai, and Pune.

Common questions about Digilent JTAG-HS3 Programming Cable

What FPGAs does the Digilent JTAG-HS3 program?

The JTAG-HS3 is an affordable high-speed programming solution for AMD (formerly Xilinx) FPGAs. It is compatible with AMD ISE 14.1 and newer and AMD Vivado 2013.3 and newer, and works with iMPACT, ChipScope, and EDK. It also adds support for debugging AMD Zynq SoC processors.

What is special about the JTAG-HS3 for Zynq debugging?

The JTAG-HS3 builds on the earlier JTAG-HS1 by adding an open-drain buffer on pin 14. This allows debugging software to reset the processor core (PS) of AMD's Zynq platform during a debug session, a capability the slimmer JTAG-HS2 does not provide. If your bring-up targets Zynq-7000 SoC boards, the HS3 is the cable to choose.

What target voltages and speeds does the JTAG-HS3 support?

The JTAG-HS3 works with any Vref between 1.8 V and 5 V and runs at up to 30 Mbit/s, with the frequency adjustable by the user. It connects to the host over a High-Speed USB 2.0 Micro-B port and uses AMD's 2x7 2 mm pitch JTAG connector on the target side.

Should I choose the JTAG-HS2 or the JTAG-HS3?

Both cables share the 1.8 V-5 V range and 30 Mbit/s speed. The JTAG-HS2 ships with both the Digilent 6-pin 100-mil header and the AMD 2x7 adapter and supports IEEE 1149.7 2-wire JTAG, with 24 mA three-state buffers for long chains. The JTAG-HS3 is a slimmer, lower-cost cable on the AMD 2x7 connector that adds the open-drain pin-14 buffer for Zynq PS reset debug. Choose HS2 for connector flexibility and 2-wire JTAG; choose HS3 for Zynq SoC debug on a budget. See our JTAG-HS2 vs HS3 comparison guide for details.

What does the Digilent JTAG-HS3 cost in India?

Final pricing depends on quantity, GST, and INR exchange rates. GSAS Micro Systems issues formal INR quotations with GeM, SAP Ariba, Coupa, and TReDS support for institutions and enterprises across India. Request a quote for current JTAG-HS3 pricing and lead time.
