It packs 58 general-purpose I/O and a full set of serial interfaces — I²C, SPI, UART, IrDA, Microwire, QEI, and SSI — making it a natural fit for motor-control, sensor-fusion, and industrial-communication nodes that need a single-core controller with moderate memory and a wide peripheral set. The industrial temperature range (-40°C to 85°C) suits factory-floor and outdoor telecom enclosures. ## Memory and peripheral budget 96 KB of Flash and 64 KB of RAM are enough for a single control loop, a Modbus RTU stack, and a modest data buffer. The two 10-bit ADC channels handle basic analog sensing — current, temperature, or potentiometer feedback. Brown-out detect, POR, PWM, and a watchdog timer are on-chip, reducing external supervisor IC count.","metaTitle":"LM3S1512-IQC25-A2 Stellaris ARM Cortex-M3 MCU, 25 MHz, 96 KB Flash","metaDescription":"LM3S1512-IQC25-A2 32-bit ARM Cortex-M3 MCU from Stellaris series. 25 MHz, 96 KB Flash, 64 KB RAM, 58 I/O, -40°C to 85°C.
