What the LM3S612-EQN50-C2 is and where it fits
The Texas Instruments LM3S612-EQN50-C2 is a 32-bit ARM Cortex-M3 microcontroller from the Stellaris family, running at 50 MHz with 32 KB of Flash and 8 KB of RAM. It packs 34 general-purpose I/O lines, two 10-bit ADC channels, and serial interfaces including I²C, SPI, SSI, and UART/USART in a compact 48-LQFP package. The -40°C to 105°C temperature grade qualifies it for industrial environments.
50 MHz core — what it means for throughput
At 50 MHz the Cortex-M3 executes single-cycle multiply and hardware divide. That clock puts this part in the mid-range of the Stellaris 600 series.
