It packs 512 KB of Flash and 96 KB of RAM, enough to run a full Ethernet stack with TCP/IP offload and a CANopen node simultaneously. The 108-ball BGA (10x10 mm) keeps the footprint compact for space-constrained industrial or building-automation controllers. ## Connectivity and peripherals at a glance This MCU integrates Ethernet MAC, CAN, USB OTG, UART, SPI, and I²C. The 16-channel 12-bit ADC samples analog signals. On-chip peripherals include PWM, QEI, and DMA. Texas Instruments has marked the LM3S9DN5-IBZ80-A1T as obsolete. No official successor part number is listed; the Stellaris family has been superseded by the Tiva C series, but pin compatibility is not guaranteed. ## Operating conditions and package The core supply is 1.235 V to 1.365 V; I/O voltage is handled separately.","metaTitle":"Texas Instruments LM3S9DN5-IBZ80-A1T Stellaris ARM Cortex-M3 MCU, 80 MHz","metaDescription":"TI Stellaris LM3S9DN5-IBZ80-A1T 32-bit ARM Cortex-M3 MCU, 80 MHz, 512KB Flash, 96KB RAM, Ethernet, CAN, USB OTG, 108-BGA.
