It integrates CAN, Ethernet, USB OTG, I²C, SPI, UART, and a 16-channel 10-bit ADC. The 80 MHz core speed supports a real-time Ethernet stack alongside a control loop and CAN messaging. The 48 KB SRAM buffers two Ethernet frames plus a data log. The 72 GPIOs and quadrature encoder interface suit motor-drive feedback.","metaTitle":"Texas Instruments LM3S9L71-IBZ80-C3 ARM Cortex-M3 MCU, 80MHz, 128KB Flash","metaDescription":"Texas Instruments LM3S9L71-IBZ80-C3 Stellaris ARM Cortex-M3S 9000 MCU, 32-bit single-core, 80MHz, 128KB Flash, 48K x 8 RAM, 108-BGA.
