The 16-channel 10-bit ADC and PWM timers suit it for motor-control or sensor-fusion nodes that also need network connectivity. ## Connectivity set — gateway-class I/O The EBI/EMI interface allows glueless connection to external SRAM, Flash, or an FPGA, which is useful if the on-chip 64 KB SRAM is tight for Ethernet buffering. The CAN controller and USB OTG mean this single MCU can act as a protocol gateway between a CAN-based machine bus and a USB-attached HMI or a factory Ethernet network. Texas Instruments has marked the LM3S9790-IQC80-C0 as obsolete. If you are in the design phase, consider whether a currently active Cortex-M3 or M4 with similar CAN/Ethernet/USB peripherals could be a pin-compatible or software-portable alternative — but no such cross-reference is documented here.","metaTitle":"LM3S9790-IQC80-C0 Stellaris ARM Cortex-M3 MCU, 80 MHz, 128 KB Flash","metaDescription":"Obsolete TI Stellaris LM3S9790-IQC80-C0 ARM Cortex-M3 MCU, 80 MHz, 128 KB Flash, 64K x 8 RAM, CAN/Ethernet/USB.
