The LM3S8630-IQC50-A2T is a 32-bit ARM Cortex-M3 microcontroller from the Texas Instruments Stellaris 8000 series. It runs at 50 MHz and packs 128 KB of Flash program memory and 32K x 8 of RAM, with a rich peripheral set that includes CAN, Ethernet, I²C, SPI, SSI, UART, and IrDA. The 100-pin LQFP package gives you 31 general-purpose I/O lines, and the operating temperature range of -40 to 85 °C makes it suitable for industrial control, building automation, and networked sensor nodes that need both fieldbus and Ethernet connectivity.
The core runs at 50 MHz using the internal oscillator.
Texas Instruments has marked the LM3S8630-IQC50-A2T as obsolete. No official successor part number has been published for this exact order code. The Stellaris family was acquired and transitioned into the Tiva C series, but pin-compatibility is not guaranteed without a full design review.
