Runs at 80 MHz with 32-bit single-core Cortex-M3, 128 KB Flash, 64K x 8 SRAM. Peripherals include 16-channel 10-bit ADC, brown-out detect, DMA, I²S, PWM, WDT. Connectivity: CANbus, Ethernet, USB OTG, I²C, SPI, UART/USART. 100-LQFP package, 1.235 V to 1.365 V supply, -40°C to 85°C. This part is marked obsolete by the manufacturer. ## 80 MHz clock — what it means for control and protocol throughput The 80 MHz Cortex-M3 core handles real-time control loops and protocol stacks without external glue logic. The integrated Ethernet MAC and CAN controllers allow this single chip to serve as a fieldbus gateway or motor drive controller, processing incoming packets and responding within microseconds. The 60 GPIOs give enough headroom for parallel sensor interfaces and display buses. Supply range 1.235 V to 1.365 V.","metaTitle":"LM3S9790-IQC80-C3 Stellaris ARM Cortex-M3 MCU, 80MHz, 128KB Flash, Obsolete","metaDescription":"LM3S9790-IQC80-C3 Stellaris ARM Cortex-M3 MCU at 80MHz, 128KB Flash, 64K x 8 RAM, 60 I/O, CAN/Ethernet/USB.
