The industrial temperature range (-40 to 85 °C) suits factory automation and motor-drive interface cards. The 50 MHz Cortex-M3 core runs a Modbus RTU stack, a PID loop at 10 kHz, and leaves headroom for ADC sampling and PWM generation. No hardware FPU — budget cycles for floating-point math. 256 KB of Flash is sized for a moderate application: a bootloader, a real-time kernel, and a few protocol stacks fit without squeezing. The 32 KB RAM handles the runtime heap and stack for a handful of concurrent tasks. If your design needs field-updatable firmware, the Flash supports in-application programming over the serial bootloader — but note that this part is obsolete, so any firmware-locked production run should be finalized before the last-time-buy window closes.","metaTitle":"LM3S1816-IQR50-C0 Stellaris ARM Cortex-M3 MCU, 50MHz, 256KB Flash","metaDescription":"LM3S1816-IQR50-C0 32-bit ARM Cortex-M3 MCU, 50MHz speed, 256KB Flash, 32KB RAM, -40 to 85°C.
