It is not automotive-grade (no AEC-Q100 mark in the record), so it belongs in the control panel, not the engine bay. ## Supply rail and power-on behaviour The POR and brown-out detect peripherals handle power-up sequencing and monitor the rail for dips during relay or motor starts — no external supervisor needed unless the system requires a tighter threshold than the internal circuit provides.","metaTitle":"LM3S800-IGZ50-C2 Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"Texas Instruments LM3S800-IGZ50-C2 32-bit ARM Cortex-M3 MCU at 50 MHz with 64 KB Flash and 8 KB RAM in 48-VQFN.
