Gang-programming solutions
Reliable tools for cost-efficient, high-volume production programming
Overview

Unlike single-device programming, gang programming is a highly efficient method used in electronics manufacturing for programming multiple devices simultaneously. This approach is particularly beneficial in setups where large numbers of microcontrollers or other programmable devices need to be programmed quickly and accurately. By significantly reducing total programming time and enhancing throughput, gang programming ensures streamlined production processes
SEGGER provides advanced gang-programming solutions that are purpose-built to meet high-volume production demands. Flasher Compact combined with Flasher Hub-12 or Flasher Hub-4, and the single-board gang programmer Flasher ATE2, support automated control through Ethernet, USB, RS232, or web interface, and they can be fully operated via command-line tools or custom scripts. Furthermore, these systems are compatible with a wide range of microcontrollers and memory types, making them suitable for diverse manufacturing needs across industries.
Key features

Impressive scalability
SEGGER gang programmers permit parallel programming of up to 24 programming units, with each unit serving as an individual channel. Both Flasher Hub-12 and its compact version, Flasher Hub-4, can be connected to as many as 24 Flasher Compacts using SEGGER’s USB Hub-7. Each Flasher can be configured individually to program different targets with different target firmware.

High-speed programming
Flasher programmers are designed to achieve top programming speeds, coming very close to the theoretical minimum programming time of the target hardware. In many cases, more than 95 % of the maximum programming speed can be achieved, meaning more than 1 MB/s.

Complete system configurability
Universal-gang-programmer systems can be controlled and configured via a built-in web server. Thanks to an intuitive user interface, all necessary information for an entire programming system is available to a user at a glance.
Use cases

Solutions for challenges in mass production
In high-volume production environments, there is no room for error. When a programming process is inefficient or leads to faulty devices, companies face not only lost production time, but also increased costs from project delays and the resources required to fix bugs and errors.
Adoption of a SEGGER gang-programming solution consisting of Flasher Compact and a Flasher Hub-4 or Flasher Hub-12 can result in significantly lower production costs, reduced programming times, enhanced programming efficiency, and processes and results that are more reliable and consistent. A case study of this solution in practice is available here.

High-volume production with ATE
Device manufacturers operating semi-automated production lines often face the challenge of integrating programming solutions into compact, space-limited test fixtures. To overcome this, the SEGGER Flasher ATE2 offers a high-density, flexible gang-programming solution designed for efficient integration into automated test equipment (ATE), where space, speed, and scalability are critical.
Standalone operation minimizes PC dependence, while built-in signal control and target power management simplify wiring and speed up reconfiguration. The result is higher throughput, reliable programming, and greater production flexibility across multiple product variants.
