Embedded electronics engineering
Razenberg Engineering develops firmware, digital logic and printed circuit boards. We also take apart existing hardware when the documentation is missing. We work from our own lab in Beuningen, the Netherlands, for clients across Europe.
We write bare-metal and RTOS firmware for 8-bit and 32-bit microcontrollers: drivers, bootloaders, communication stacks and low-power designs. We bring up new boards, and we take over existing code that someone else started and never finished.
We design digital logic in VHDL and Verilog: high-speed interfaces, signal processing, custom peripherals and soft-core integration. We simulate the design, close timing, and debug on the chip itself when the simulation and the hardware disagree.
We analyse existing hardware and firmware: protocol decoding, firmware extraction and disassembly, schematic recovery from boards, and talking to devices nobody documented. Typical reasons are a repair, a move away from an obsolete part, or a security review of a product you own or are licensed to work on.
We do schematic capture and layout, from small single-sided boards to multi-layer designs with fine-pitch components. We pick parts that are in stock, and we assemble and test the prototypes in our own lab.
