    Why reliable programming matters

    Reliable programming lies at the core of modern electronics manufacturing, and SEGGER’s Flashers deliver robust, secure, and scalable solutions for every programming requirement — from prototype testing to high-volume production. Transferring firmware to a microcontroller’s flash memory, a key step in the programming process, demands speed, efficiency, and reliability.

    Key features

    SEGGER Flashers are a professional line of in-system programmers (ISP) designed for use in service environments, prototype programming, and mass production. They are capable of programming non-volatile flash memory in microcontrollers, systems on a chip (SoCs), and external SPI-style flash memory, and they can support both serial and parallel data transfer over multiple I/O pins.

    High throughput

    The flash programming algorithms for SEGGER's Flasher production programmers use a turbo mode that enables programming speeds that are as close to the theoretical maximum as possible.

    Hassle-free reconfiguration

    SEGGER offers a simple approach for swapping target devices. If the in-system programmer supports the new device, it can be programmed—even if support for the device was introduced after the initial purchase.

    High yield rates

    SEGGER's Flasher production programmers are highly reliable, offer multiple levels of verification during the programming process, and utilize proven and thoroughly tested algorithms.

    Use cases

    SEGGER’s Flasher solutions optimize microcontroller programming across diverse scenarios. From prototype testing to secure high-volume production, SEGGER’s Flashers are designed to meet the needs of every stage of the manufacturing process.

    In-field firmware updates for remote devices

    To update firmware on devices deployed in remote locations, technicians can use SEGGER’s Flasher Portable PLUS to program each microcontroller on-site in the field.

    Instead of returning devices for updates, users can employ these single-programming tools to provide reliable, precise firmware updates, saving time and costs while keeping all devices up-to-date and operational.

    An illustrated diagram shows a central device labeled "Flasher Hub-4," connected to multiple smaller devices labeled "Flasher." Lines connect these devices to an Automated Test Equipment (ATE) system, indicating a network setup for device communication and testing.

    High-volume gang programming for consumer electronics

    For consumer electronics in high demand, production speed is critical. The Flasher Hub-12 and Hub-4 paired with Flasher Compact units create a powerful gang programming solution, enabling simultaneous programming of multiple devices. This setup maximizes throughput while minimizing the physical footprint required, making it perfect for automated production lines where space and efficiency are priorities.

    With the ability to control multiple Flashers at once, SEGGER’s gang programming solutions support fast, scalable production with minimal downtime.


    Single-unit programming

    Single-unit in-system programming devices are designed to program individual microcontrollers, SoC, or memory components with specific firmware, making them ideal for production environments or in-field updates. SEGGER’s Flasher series provides reliable, high-quality in-system programming solutions tailored to various needs. Each device offers unique features to support efficient, precise programming in diverse applications.

    Flasher PRO

    The "almost-anything" programmer

    The Flasher PRO is SEGGER’s full-featured, in-system universal flash programmer for microcontroller, SoC, and (Q)SPI flashes.

    A blue and grey electronic device labeled "Flasher Pro XL" from SEGGER is prominently displayed. The device features indicators for "Ready," "Not Ready," and "Fail," suggesting its function as a programmer for electronic components. It is set against a blurred background of circuit board elements.

    Flasher PRO XL

    The universal flash programmer for huge images

    The Flasher PRO XL is a Flasher PRO with extra-large memory capacity, designed to program huge images for use during the production programming process.

    A blue and gray programming device labeled "Flasher" for ARM microcontrollers. The front features buttons and indicators for status: "Ready," "Not ready," and "Fail." It is shown against a blurred background of electronic components, highlighting its function in programming hardware.

    Flasher ARM

    The flash programmer for Arm-based microcontrollers

    The Flasher ARM is SEGGER’s full-featured, in-system flash programmer specifically limited to Arm-based microcontrollers.

    A blue and gray portable programming device labeled "Flasher Portable PLUS" is shown. It features a small screen displaying "Programming..." and a progress percentage. The device has buttons for power, programming (PROG), and selection (SEL). It appears to be used in electronics development or testing.

    Flasher Portable PLUS

    The battery-powered portable service programmer

    The Flasher Portable PLUS is a handheld, battery-driven, standalone flash programmer, designed to meet the need for an extremely portable, production-grade flash programmer for in-field firmware updates.

    A compact blue device labeled "Flasher" by SEGGER is prominently displayed. The device includes status indicators: "Ready / O.K." and "Not ready / Fail," along with a "PROG" button. The background features a blurred circuit board to indicate its technological context.

    Flasher Compact

    The space-efficient programmer

    The Flasher Compact is a space-efficient counterpart to the Flasher PRO that is ideal for integration into production rigs or automated test equipment (ATE) where Ethernet connectivity is not needed. Paired with the Flasher Hub-4 or Flasher Hub-12, it enables highly efficient gang-programming solutions.


    Gang programming

    In electronics and manufacturing, gang programming is a highly efficient method for programming multiple devices simultaneously. This approach is particularly beneficial in scenarios where large numbers of microcontrollers or other programmable devices need to be programmed quickly and accurately.

    SEGGER offers several cost-effective gang programming solutions for high-volume in-system programming.
