Includes CAN, I²C, SPI, UART, six 10-bit ADC channels, PWM, DMA, and a brown-out detector. ## 50 MHz, 64 KB Flash, 32 KB RAM — fit check The 50 MHz core is enough for a control loop running at a few kilohertz with a CAN message stack and a UART debug channel. The 64 KB Flash holds a moderate firmware image — think bootloader plus application code for a motor drive or a remote I/O node. The 32 KB RAM gives headroom for a couple of CAN message buffers and a small data log. ## Industrial temperature grade","metaTitle":"LM3S2276-IQR50-A0 Stellaris ARM Cortex-M3 MCU, 50 MHz, 64 KB Flash","metaDescription":"Obsolete LM3S2276-IQR50-A0 32-bit ARM Cortex-M3 MCU from TI. 50 MHz core, 64 KB Flash, 32 KB RAM, CAN/I²C/SPI/UART.
