On-chip brown-out detect, POR, PWM, and watchdog timer reduce the need for external supervisory ICs in an industrial control application. ## Package and supply rail Housed in a 48-LQFP (7x7 mm) surface-mount package, the part is suited for reflow assembly on a standard 4-layer board. The 3.0–3.6 V single supply rail simplifies power-tree design. ## Lifecycle reality — obsolete, sourced through surplus channels Texas Instruments lists this part as Obsolete. Quantities are lot-specific; confirm availability and pricing at RFQ time.","metaTitle":"TI LM3S828-IQN50-C2 ARM Cortex-M3 MCU, 50 MHz, 64 KB Flash","metaDescription":"Texas Instruments LM3S828-IQN50-C2 Stellaris ARM Cortex-M3 MCU, 50 MHz, 64 KB Flash, 8 KB SRAM, 48-LQFP.
