The 31 GPIOs, internal oscillator, and brown-out/POR/WDT peripherals reduce external component count in space-constrained 100-LQFP designs. The 50 MHz Cortex-M3 core runs a TCP/IP stack alongside a CANopen master or Modbus TCP gateway without a separate protocol coprocessor.","metaTitle":"Texas Instruments LM3S8630-EQC50-A2T ARM Cortex-M3 MCU, 50MHz","metaDescription":"Obsolete TI Stellaris LM3S8630-EQC50-A2T ARM Cortex-M3 MCU, 128KB Flash, 32KB RAM, 50MHz, Ethernet, CANbus, -40°C to 105°C, 100-LQFP.
