The 80 MHz core delivers single-cycle multiply and hardware divide, so a PID loop or protocol stack (TCP/IP, CANopen) runs without a heavy clock-stretch penalty. For a motor-drive or networked sensor node, this speed class handles the control math and Ethernet frame processing on one core. Texas Instruments has designated the LM3S9790-IBZ80-C5 as obsolete (EOL). No direct pin-compatible replacement is listed in the Stellaris family; the Stellaris line has been phased out. ## Industrial temperature and BGA package notes X-ray inspection is recommended after reflow to verify solder-joint integrity under the package.","metaTitle":"LM3S9790-IBZ80-C5 Stellaris ARM Cortex-M3 MCU, 80 MHz, 128 KB Flash","metaDescription":"LM3S9790-IBZ80-C5 is a Stellaris ARM Cortex-M3 MCU with 80 MHz core, 128 KB Flash, 64K x 8 RAM, Ethernet, USB OTG.
