Texas Instruments has marked the LM3S2730-EQC50-A2 as Obsolete. 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.
