US corporation with a field-proven product from the early 2000s
A multinational US-based corporation with a strong global presence and operations across Europe, delivering products designed for demanding industrial environments.
One of its key solutions, originally introduced in the early 2000s, remained widely used and commercially successful, creating a need to sustain its availability and competitiveness over time.
Why obsolete components threatened a proven harsh-environment product
The product had proven its reliability in harsh environments over many years, but its long-term viability was increasingly at risk due to the diminishing availability of critical components.
As hardware parts became obsolete, maintaining production and servicing existing deployments became more difficult, threatening both product continuity and customer trust.
At the same time, any redesign had to preserve the original system’s behavior and reliability, which had already been validated in demanding real-world conditions. This created a delicate balance between modernization and stability, where introducing new technologies could not compromise the proven performance of the existing solution.
Requirements for replacing obsolete parts without a full redesign
To secure the future of the product, the solution needed to:
- replace obsolete components with long-term available alternatives
- maintain compatibility with existing system behavior
- ensure reliability in harsh operating environments
- improve energy efficiency and hardware performance
- support future development and scalability
The goal was not to redesign the product from scratch, but to extend its lifecycle while preserving its core value.
Component-level redesign that keeps the proven architecture
A comprehensive redesign approach was introduced, focused on modernizing the system while retaining its proven architecture and operational characteristics. Instead of replacing the product entirely, the effort centered on carefully evolving its components, ensuring that each change aligned with existing functionality and performance expectations.
New hardware components were selected based on long-term availability, reliability, and energy efficiency, reducing the risk of future obsolescence. The embedded systems development work also involved integrating modern software practices with legacy solutions to improve maintainability and flexibility while preserving the system's core behavior.
The process was supported by a feasibility study and a structured development roadmap, enabling a controlled transition from legacy architecture to a future-ready solution.
The project demonstrates how architecture planning, hardware selection, and software integration contribute to successful legacy system modernization. Our guide to the embedded system design process explains these engineering considerations in more detail.

By combining legacy stability with modern flexibility, the solution ensures long-term competitiveness in demanding industrial markets.
Frequently asked questions
Can an obsolete embedded data transmission product be modernized without a full redesign?
Yes. A component-level redesign can replace obsolete parts while retaining the proven architecture and operational characteristics. In this project, InTechHouse selected new hardware for long-term availability, reliability and energy efficiency and kept the original product logic, so a harsh-environment product introduced in the early 2000s could stay in production and servicing for existing customers.
How do you preserve legacy system behavior when moving harsh-environment hardware to ARM Cortex-M4 and FPGA?
By evolving components carefully and checking that each change aligns with existing functionality and performance expectations. In this project, InTechHouse started from a feasibility study and a structured development roadmap, then ran updated embedded C/C++ software on ARM Cortex-M4 microcontrollers and FPGA logic, using embedded software debugging tools for validation and testing.
What does a component obsolescence redesign deliver for an industrial product already in the field?
A component obsolescence redesign extends the product lifecycle and secures component supply without replacing the product. In this project, InTechHouse modernized a harsh-environment data transmission product so it could keep being manufactured and serviced, which protected the existing customer base, improved performance and energy efficiency through modern hardware, and allows new features without disrupting existing deployments.
