The SONE033 defect—a latent timing‑race condition in the SONE‑Series line of low‑power microcontroller units (MCUs) used in safety‑critical IoT devices—has been reported across multiple automotive and industrial applications. The defect manifests as intermittent watchdog failures and spurious peripheral resets under high‑throughput DMA transactions, jeopardising functional safety (ISO 26262 ASIL B). This paper presents a systematic approach to diagnosing, fixing, and validating the SONE033 anomaly. We first analyse the root cause through static code analysis, formal model checking, and hardware‑level signal tracing, revealing an off‑by‑one error in the DMA‑channel arbitration logic that corrupts the fixed‑point timer register (TIMER0). A fixed‑point remediation—re‑architected as a deterministic, lock‑step arbitration scheme with bounded latency—is implemented in both the silicon micro‑architecture (revision R2.1) and the firmware abstraction layer (v5.4.2). Comprehensive verification is performed using a combination of cycle‑accurate simulation, hardware‑in‑the‑loop (HIL) testing, and statistical fault injection. Results show a 100 % elimination of the failure mode under the worst‑case traffic pattern and a negligible (< 0.3 %) impact on power consumption and latency. The paper concludes with guidelines for early detection of similar fixed‑point race conditions in future MCU designs. : Delete temporary files left behind in the
