Sourcing is through independent distribution — quantities and pricing confirmed at RFQ against your BOM line. ## Core architecture and memory configuration Built around the ARM Cortex-M3 core at 50 MHz, the LM3S2730-EQC50-A2 is a 32-bit single-core MCU from the Stellaris ARM Cortex-M3S 2000 series. The 2.25 V to 2.75 V supply range means the core and I/O share a single low-voltage rail — a 2.5 V regulator is the typical choice. ## Peripherals, I/O, and temperature grade On-chip peripherals include brown-out detect, POR, DMA, PWM, and a watchdog timer. Connectivity covers CAN, IrDA, Microwire, SPI, SSI, and UART/USART — the CAN 2.0B controller is useful for industrial or automotive sub-networks. The 100-LQFP (14x14 mm) footprint is a standard fine-pitch package — a 4-layer PCB with a solid ground plane under the QFP is recommended for signal integrity at 50 MHz.","metaTitle":"LM3S2730-EQC50-A2 Texas Instruments ARM Cortex-M3 MCU, 50MHz","metaDescription":"Texas Instruments LM3S2730-EQC50-A2 ARM Cortex-M3 MCU, 50MHz, 128KB Flash, 64KB RAM, 100-LQFP.
