What this part is and where it fits
The LM3S6110-EQC25-A2T is a 32-bit ARM Cortex-M3 microcontroller from the Stellaris 6000 series, built for industrial control and networked embedded systems. It runs at 25 MHz with 64 KB of Flash program memory and 16K x 8 of SRAM, enough for moderate control loops and protocol stacks. The on-chip Ethernet MAC and PHY, plus UART/USART, SPI, SSI, and IrDA interfaces, make it a natural fit for factory-automation gateways, remote I/O modules, and building-management controllers that need a wired network connection without an external transceiver. The operating temperature range is -40°C to 105°C. The supply voltage is 2.25 V to 2.75 V.

Memory sizing and peripheral set
64 KB of Flash and 16 KB of SRAM set a firm boundary on firmware complexity. The peripheral list includes brown-out detect, POR, PWM, and WDT.
