Secure Renesas Controller Development
Budget: ₹12,500 – ₹37,500 INR
I’m building a prototype around a TrustZone-enabled Renesas MCU that must meet tight security requirements while handling 4 digital inputs, 4 digital outputs, 2 relays, 2 analog inputs, plus Bluetooth and Wi-Fi connectivity. Hardware and firmware are moving in parallel, but I now need extra horsepower on both fronts.
On the hardware side the immediate focus is full-cycle support: schematic capture, board layout, prototyping, bench testing, and clean integration of every section—power, relays, analog front end, RF modules, and debug interfaces. Schematics and PCB files should be delivered production-ready with a complete BOM and clear test reports so I can push the design straight to a short run.
Firmware must preserve TrustZone isolation and enforce restricted user logins while driving the peripherals and wireless stacks. Clean, well-documented C/C++ (or Renesas-preferred toolchain) is essential, along with OTA-friendly builds so future updates remain secure.
Key acceptance points
• Hardware: validated prototypes showing stable I/O, relay drive and analog accuracy, plus RF range tests over BLE and Wi-Fi.
• Firmware: authenticated login flow, verified TrustZone boundary, reliable Bluetooth/Wi-Fi data exchange, and source code that compiles without warnings in the provided environment.
Milestones will be split between board release, prototype test results, and firmware feature drops so progress stays easy to measure. If you have proven Renesas, TrustZone or similar secure-MCU experience and can jump straight into joint design reviews, let’s connect and lock in the timeline.
