The 32-bit single-core Cortex-M3 handles 16/32-bit multiply-accumulate in a single cycle. ## Peripherals and I/O — what connects 43 GPIOs in a 100-LQFP package, plus four 10-bit ADC channels, a PWM module, brown-out detect, POR, and a watchdog timer. The connectivity set covers I²C, SPI, SSI, UART, IrDA, and Microwire — enough to talk to most sensor modules, serial displays, and industrial fieldbus transceivers. No CAN or USB on this die, so if the application needs a CAN node or a USB virtual COM port, this isn't the part. ## What compliance documentation is available The LM3S1165-EQC50-A2 is a standard commercial semiconductor — TI provides the datasheet, a revision history, and RoHS/REACH declarations on request. No UL, IEC, or military certification on record for this order code.","metaTitle":"LM3S1165-EQC50-A2 Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"LM3S1165-EQC50-A2 from Texas Instruments — Stellaris ARM Cortex-M3 MCU, 50 MHz, 64 KB Flash, 16 KB RAM, industrial temp -40°C to 105°C.
