25 MHz Cortex-M3 with 16 KB flash — the firmware budget check
The LM3S328-EGZ25-C2: At 25 MHz the Cortex-M3 core delivers deterministic interrupt latency for control loops — the 16 KB flash holds the application code plus the bootloader, so read the linker map before committing the firmware.
Industrial temperature grade and on-chip peripherals
On-chip peripherals include brown-out detect, POR, PWM, and a watchdog timer, plus I²C, Microwire, SPI, SSI, and UART/USART connectivity — enough to interface with sensors, actuators, and serial displays without external glue logic.
