Single-unit programming solutions
A complete family of proven and reliable devices
Overview
Single-unit programming involves deploying software to a single dedicated microcontroller or processor within a larger system. SEGGER's single-unit Flasher programmer family includes the Flasher Pro, Pro XL, Compact, and Portable PLUS.
These universal in-system programming (ISP) tools provide reliable single-unit microcontroller and system-on-a-chip (SoC) programming and are engineered to meet all of the embedded industry's flash programming requirements.
SEGGER single-unit programmers offer unique features; support a wide range of microcontrollers, memory types, and interfaces; and are available in form factors that are flexible enough to work in any setup — whether on the factory floor or out in the field.
Key features
Stand-alone operation
Each Flasher single-unit programmer is designed to operate independently, without the need for a connected PC. This standalone capability ensures that programming tasks are performed efficiently and reliably in any environment.
Maximum speeds
SEGGER Flash Loaders deliver unmatched write performance with Turbo Mode technology and optimized hardware for maximum programming speeds across all target interfaces. This means that users can get very close to achieving theoretical minimum programming times for target hardware. In many cases, more than 95 % of a maximum possible programming speed is achievable, which typically means more than 1 MB/s.
Serial-number assignment
Many modern devices require unique data. Flasher devices allow 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.
Use cases
Flasher programmers are the ideal solution for single-line production setups and prototype creation. With fast programming speeds, flexible interfaces, and proven reliability, they help optimize production lines and enable efficient, independent prototype testing and consistent quality.
Single-line production
In single-line production setups, units are programmed one at a time. Members of the Flasher single-programming family are easy to integrate into these lines. Flasher's flexible interfaces allow for local or remote updates, its programming speed minimizes production time, and its reliability ensures a high yield rate.
Prototype creation
Pre-production testing requires prototypes. To create prototypes, development teams prepare Flasher units for use in standalone mode (with a firmware image), and they set up data for the prototype. A testing team then uses these units to create prototypes. Should something go wrong, the prototype's original setup can be restored without the aid of a development team.
