XJTAG Launches Two new Flash Programmers: XJExpress and XJExpress-FPGA

XJExpress is a directly-connected in-circuit SPI flash programmer. XJExpress-FPGA allows for in-circuit programming of flash memory attached to an FPGA

Key features of both products include:

• Easy-to-use – easily configurable and intuitive for all types of users with simple control of erase, program and verify stages across multiple targets
• Fast – able to outperform competitors’ cycle times with intelligent erase, program and verify algorithms
• Reliable – developed from factory-proven hardware and with enhanced termination protection
• Powerful – support for a huge range of SPI NOR flash devices as well as serial, dual and quad SPI modes
• Multi-image support – combine multiple files during programming
• Adaptable – GUI and command-line control options
• Flexible – with connection options via direct cable or in-circuit test (ICT) systems
• Proven – part of the XJTAG ecosystem of test and programming tools

Cambridge, United Kingdom. 8 October, 2025 – XJTAG®, a leading provider of test and programming solutions, is excited to announce XJExpress and XJExpress-FPGA – a pair of flash programmers perfect for development, debug, production and in-service applications. Designed to offer engineers an easy-to-use, lightning-fast and reliable way to program flash memory, they are the go-to solution when the pressure is on, whether you want to program the flash through direct connection with XJExpress or via a connected FPGA device with XJExpress-FPGA.

XJExpress

Building on years of experience in electronics design and development, XJExpress has an adaptable and powerful interface with flexibility to configure erase, programme and verify cycles across multiple targets with ease. You can choose to get started quickly using the expertly-designed software to your advantage and get programming in seconds or alternatively, XJExpress can be launched from the command-line for integration into automated workflows or third-party platforms.

XJExpress connects directly to SPI flash memory on a circuit board or assembly to deliver high speed in-system erase, program and verify functionality. In most cases the limit on the speed achieved will be the write time for the flash memory device being programmed, demonstrating XJExpress’ ability to exceed real-world demands. Combining that with intelligent algorithms to optimise cycle times means engineers can be confident with XJExpress throughout the whole product lifecycle.

The programmer is self-contained and USB-connected with the robustness and reliability you would expect from XJTAG’s years of experience in production environments. XJExpress combines a rugged form factor with enhanced termination protection on all pins, ensuring electrical robustness and reliability.

“XJExpress offers the power of high-speed flash programming without the overhead of full system integration,” said Simon Payne, CEO of XJTAG. “It’s plug-and-play, scriptable, and built for speed.”

Whether used on the bench or integrated into production systems, XJExpress simplifies and accelerates direct SPI flash programming, helping engineers streamline programming and saving time.

XJExpress-FPGA

XJExpress-FPGA is pre-configured by XJTAG for the FPGA and flash types you’re using, so you can immediately get programming at blisteringly high speed. It connects to the FPGA or FPGA SoC using the ubiquitous JTAG port and again the write speed of the flash is typically the limit to programming speed.

“XJExpress-FPGA provides the industry’s highest-speed flash programming, over JTAG, for both development and production,” said Pete Wootton, Head of Hardware of XJTAG. “Its speed is truly astonishing”

Whether used on the bench or integrated into production systems, XJExpress-FPGA simplifies and accelerates flash programming for FPGA and FPGA SoC applications, helping engineers streamline programming and saving time.
