It includes CAN, Ethernet, I²C, SPI, SSI, UART, and IrDA connectivity. ## 256 KB Flash and 64 KB RAM — firmware headroom for protocol stacks The 256 KB Flash holds a TCP/IP stack plus application code; the 64 KB RAM leaves room for packet buffers and real-time data. The 50 MHz Cortex-M3 delivers deterministic interrupt response for the PWM and WDT peripherals — useful for motor-control loops that cannot tolerate jitter. The 100-LQFP (14x14 mm) package keeps the board footprint compact. ## End-of-life status — sourcing via independent channel End-of-life. Sourcing runs through the surplus and broker channel.","metaTitle":"LM3S8933-IQC50-A2 Stellaris ARM Cortex-M3 MCU, 50 MHz, 256 KB Flash","metaDescription":"LM3S8933-IQC50-A2 32-bit ARM Cortex-M3 MCU from TI Stellaris series. 50 MHz core, 256 KB Flash, 64 KB RAM, CAN/Ethernet/I²C/SPI/UART.
