The integrated Ethernet PHY saves a separate transceiver chip and the associated PCB routing, which matters in the 100-LQFP package where board space is tight.","metaTitle":"LM3S6730-EQC50-A2 Stellaris ARM Cortex-M3 MCU, 50 MHz, 128 KB Flash, Ethernet","metaDescription":"Obsolete LM3S6730-EQC50-A2 32-bit ARM Cortex-M3 MCU from TI's Stellaris series. 50 MHz, 128 KB Flash, 64 KB RAM, Ethernet, IrDA, SPI, UART. -40 to 105°C.
