System Architecture and Scalability
The SEGGER Flasher ATE Main Module forms the central communications hub in a modular high-volume flash programming system. As the mainboard controller, it manages command distribution between host ATE systems and up to 10 individual programming modules via an internal bus architecture. This modular approach enables unprecedented scalability in production environments, allowing manufacturers to configure systems from single-module prototyping setups to full 10-module high-throughput production lines.
Each programming module operates independently with its own 128MB memory storage, programming circuit, and target interface. The Main Module coordinates these resources whilst maintaining functional isolation between programming channels, preventing cross-contamination and enabling simultaneous programming of different target types or firmware versions.
Communication Interfaces and ATE Integration
The Main Module provides comprehensive connectivity options for diverse production environments. The primary interfaces include:
| Interface | Specification | Use Case |
|---|---|---|
| Ethernet | 10/100 Mbit | Remote control, FTP access, web monitoring |
| USB 2.0 | High-Speed | PC configuration, firmware updates |
| RS232 | 9-pin | ATE handshake control, ASCII commands |
The RS232 interface supports both simple 3-wire handshake control for basic ATE integration and full ASCII command protocol for advanced remote control with detailed status reporting.
Target Interface Support and Programming Capabilities
Programming modules connect to targets via standard 20-pin JTAG/SWD connectors with support for various interface types through optional adapters. The system utilises the same proven flash algorithms found in SEGGER's J-Link debug probes, ensuring reliable programming across diverse microcontroller families.

Memory Storage and File Management
Each programming module incorporates 128MB of non-volatile memory for storing configuration files, firmware images, and programming data. The integrated FTP server provides network-based file access, with each module appearing as a separate directory (Module.001 through Module.010) in the file system hierarchy.
File transfers support both standard firmware formats (Intel HEX, Motorola S-Record, binary) and SEGGER's native .DAT format for optimal programming performance.
Operating Modes and Control Methods
Remote-Controlled Mode
In remote-controlled mode, the Main Module receives commands via Ethernet, USB, or RS232 ASCII interface. This mode provides comprehensive status reporting, error diagnostics, and programming verification, making it ideal for automated production lines requiring detailed process monitoring.
Handshake Mode
Handshake mode enables direct ATE integration through simple digital I/O signals via the RS232 connector. Programming operations are triggered by hardware signals without requiring host PC interaction, streamlining integration into existing production equipment.
Setup and Configuration Workflow
Initial system configuration utilises J-Flash software to create project files containing target-specific programming parameters. These configuration (.CFG) and data (.DAT) files are then uploaded to individual modules via FTP, enabling autonomous operation without ongoing PC connectivity.
- Project Creation: Use J-Flash to configure target device, memory layout, and programming options
- File Generation: Export configuration and firmware files in SEGGER format
- FTP Upload: Transfer files to appropriate module directories via network connection
- Module Selection: Configure FLASHER.ini files to specify active project per module
- Verification: Test programming operations before production deployment
Serial Number Programming and Traceability
The system supports automatic serial number programming for production traceability requirements. Serial numbers can be programmed as continuous sequences, from predefined lists, or with custom patch data applied per programming cycle. This capability ensures unique device identification whilst maintaining high-throughput programming speeds.
Web Interface and Remote Monitoring
The integrated web server provides browser-based access to system status, configuration parameters, and operational statistics. Production managers can monitor programming progress, view error logs, and adjust system parameters remotely without specialised software installation.
| Web Interface Feature | Functionality |
|---|---|
| System Overview | Module status, programming progress, error indicators |
| Network Configuration | IP settings, DHCP configuration, connectivity status |
| Module Management | Individual module control, firmware versions, memory usage |
| Log Access | Programming logs, error history, statistical reports |
