The 100-pin LQFP package (14x14 mm) exposes 65 GPIOs. The core logic runs from a 1.235 V to 1.365 V supply rail, which means a separate 1.3 V regulator is needed alongside the 3.3 V I/O rail — a two-supply design that the board layout must accommodate. ## 128 KB Flash, 64 KB RAM — memory sizing for the application With 128 KB of on-chip Flash and 64 KB of SRAM, this part fits firmware images for a TCP/IP stack with a small web server, a CANopen node, or a USB device class driver. The 64 KB RAM provides enough headroom for Ethernet packet buffers and a modest RTOS heap.","metaTitle":"LM3S9792-IQC80-C1 Stellaris ARM Cortex-M3 MCU, 80MHz","metaDescription":"LM3S9792-IQC80-C1 Stellaris ARM Cortex-M3 MCU, 80MHz, 128KB Flash, 64KB RAM, Ethernet, USB OTG, CAN, -40°C to 85°C.
