Flasher PRO
The most versatile flash programmer on the market
Overview
Flasher PRO is a universal in-system programming (ISP) tool for reliable single-unit microcontroller and system-on-a-chip (SoC) programming. Engineered to meet all of the industry's flash programming requirements, it supports a wide range of microcontrollers and memory types, ensuring compatibility across a wide range of embedded systems. Flasher PRO can program over 20,000 devices, supports hundreds of different interfaces, and is flexible enough to work in any setup — whether on the development bench, in the lab, or on the factory floor. With a robust feature set that includes high-speed programming options, a built-in FTP server, remote control, trigger options, and detailed logging, it is ideal for both prototyping and production environments. Its ability to deliver fast, scalable, and reliable programming solutions make it the perfect choice for bringing efficiency and flexiblity to mass production.
Key features
High-speed programming
Flasher PRO achieves programming speeds that approach the theoretical maximum. For MCUs that allow memory access while running, for example, Flasher PRO’s "turbo mode" minimizes overhead by downloading and programming simultaneously, enabling unmatched speeds.
Serial-number assignment
Many modern devices require unique data. Flasher PRO enables programming of variable information, such as serial numbers, Ethernet hardware addresses (MAC), digital signatures, and license keys. These options can be customized for each device by applying patch data to the original firmware.
Flexible control
With SEGGER software tools, Flasher PRO is easy to set up and use. With the ability to operate as a standalone programmer or be controlled via PC, Flasher PRO offers flexibility for production. In standalone mode, it supports remote control via USB, UART, Ethernet, a TTL trigger, or the push of a button.
Use cases
Boosting production at scale
Flasher PRO is built to maximize programming speed for single or multiple programming lines within production environments. Using (Q)SPI, Flasher PRO minimizes programming times, thus maximizing the number of devices that can be programmed in a given amount of time.

Varying hardware platforms in production environments
In production environments, different types of hardware platforms often have to be programmed with different firmware images. Flasher PRO is universal, meaning these different platforms can be programmed with just one device. Users can store multiple data and configuration files, and it is even possible to program multiple targets located in a JTAG chain. Each target can be programmed with an individual configuration and a data file.
How Flasher PRO works
Flasher PRO writes firmware to a device's non-volatile memory, verifies the contents, and provides immediate feedback through LEDs, software, or via hardware interfaces. It connects to target devices via standard interfaces, and operates in either PC-controlled or standalone mode. In PC-controlled mode, programming is managed directly from a host computer using SEGGER tools like J‑Flash. In standalone mode, Flasher PRO uses preloaded firmware images stored in its internal memory. Programming can be triggered through the press of a button, a TTL signal, or remotely via USB, UART, RS232, or Ethernet. Since the feedback can be read directly over the host interfaces, software is not necessarily required for evaluation.
Supported devices
The list of supported manufacturers, families, devices, and SoCs includes tens of thousands of devices in hundreds of device families.

Flasher DSK
If a new device needs to be programmed which does not already have Flasher support, users can implement device support themselves via the Flasher Device Support Kit (DSK). It is directly available from the Web Shop and includes the necessary documentation, example scripts, and tools to implement the programming process for targets not supported by default. This makes the Flasher DSK especially suitable for developers looking to integrate proprietary hardware or new components into their production workflows, ensuring that their production setup will work with any target memory they choose.
Software
A multi-platform solution, Flasher PRO comes with SEGGER's Flasher Software and Documentation Package for Windows, Linux, and macOS. It provides the tools and resources necessary for configuring, managing, and using Flasher PRO effectively. It also includes flash loaders for all supported devices, including a wide range of target microcontrollers. The list of supported manufacturers, families and devices, and SoCs provides a detailed overview.
The software package can be downloaded free of charge, and it includes future software and firmware updates as well as all new flash loaders for target devices added in the future.
Support
Flasher PRO comes with one year (12 months) of Basic Support. Beyond that, SEGGER's Extended Coverage gives users the option to extend the hardware warranty and Basic Support for one additional year (12 months) or two additional years (24 months). These options are only available at the time of purchase, either through the Web Shop or upon request; adding coverage at a later date is not possible.
