That matters for designs where the MCU handles both application logic and real-time network responses — the 80 MHz clock keeps the CPU from becoming the bottleneck. ## EOL — sourcing reality for this part ## Peripheral set — what you get on-chip On-chip peripherals include a 16-channel 12-bit ADC, internal oscillator, brown-out detect, POR, PWM, watchdog timer, and a DMA controller. This is a full-featured control-and-communications MCU that can serve as a single-chip gateway or sensor-fusion node.","metaTitle":"Texas Instruments LM3S9U92-IBZ80-A2T ARM Cortex-M3 MCU, 80 MHz, 384 KB Flash, 10","metaDescription":"TI Stellaris LM3S9U92-IBZ80-A2T ARM Cortex-M3 MCU, 80 MHz, 384 KB Flash, 96 KB SRAM, Ethernet MAC+PHY, USB OTG, dual CAN, 65 I/O, -40 to 85 °C, 108-BGA.
