Cortex-M3 core at 50 MHz — what it means for the BOM line
The LM3S828-IQN50-C2: The 32-bit single-core processor handles control loops, protocol stacks, and sensor fusion without an external memory bus — the on-chip memory budget determines the application ceiling. 28 general-purpose I/O lines and an 8-channel 10-bit ADC mean a single chip can read analog sensors and drive digital outputs, reducing the external component count in a compact control board.
Peripherals and connectivity for panel integration
Serial interfaces include I²C, SPI, SSI, and UART/USART — enough to talk to common peripherals like temperature sensors, serial EEPROMs, or a host controller over a simple backplane. On-chip brown-out detect, POR, PWM, and watchdog timer reduce the need for external supervisory ICs in an industrial control application.
Package and supply rail
Housed in a 48-LQFP (7x7 mm) surface-mount package, the part is suited for reflow assembly on a standard 4-layer board. The 3.0–3.6 V single supply rail simplifies power-tree design.
