This chapter lists the features of the current Flasher models.
Flasher connects to a PC using the USB/Ethernet/RS232 interface (what host interfaces are available depends on the Flasher model), running Windows, Linux & MacOS. In stand-alone mode, Flasher can be driven by the "PROG" button, or remote (handshake control or ASCII interface): #Remote Control Flasher always has a 20-pin connector, which target interfaces are supported depends on the Flasher model:
- Flasher ARM: JTAG and SWD.
- Flasher PRO/Compact/Portable PLUS: JTAG, SWD, SPI, cJTAG and many more.

- ↑ The ST STM32WB1x devices are special compared to the other STM32WB devices e.g. the sector size is 2KB instead of 4KB. As a legitimate owner of a SEGGER Flasher, you can always download the latest software free of charge. Though not planned and not likely, we reserve the right to change this policy. Note that older models may not be supported by newer versions of the software. Typically, we support older models with new software at least 3 years after end of life.

Working environment
General
The Flasher can operate from a PC with an appropriate software like J-Flash or in stand-alone mode.
Host System
IBM PC/AT or compatible CPU: 486 (or better) with at least 128MB of RAM,
running Windows, Linux & MacOS. It needs to have a USB, Ethernet or RS232 interface available for communication with Flasher.
Power supply
- Flasher Portable PLUS: internal rechargeable 680mAh Li-Ion battery, min. 100 mA via USB connector.
- Other Flashers: 5V DC, min. 100 mA via USB connector.
Installing Flasher PC-software
The software is part of the Flasher Software and Documentation Pack, which you can download here: Download.
More information about the package you can find in the similar J-Link Software and Documentation Pack.
The package includes U-Flash and J-Flash, the main tools for flashing targets:
- J-Flash : J-Flash User Guide (UM08003_JFlash.pdf).
