The internal oscillator eliminates an external crystal for many applications, though the UART and I²C peripherals still need accurate bit timing if the internal RC drifts outside the tolerance for the baud rate. On-chip brown-out detect and a watchdog timer (WDT) reduce the external supervisor IC count — the POR circuit holds the core in reset until the supply is stable, and the WDT catches firmware hangs without a separate watchdog chip. ## Active lifecycle — sourcing posture for production and spares The part ships in tray packaging (per the spec record), which is the standard delivery format for 100-LQFP devices. Reels are not the default — if tape-and-reel is required for automated pick-and-place, confirm the alternate order code with the supplier at RFQ time.","metaTitle":"Texas Instruments LM3S1960-IQC50-A2 ARM Cortex-M3 MCU, 50MHz","metaDescription":"Active-production Stellaris ARM Cortex-M3 MCU, 50MHz, 256KB flash, 64KB RAM, 100-LQFP, -40 to 85°C.
