The 60 GPIOs, combined with I²C, SPI, SSI, UART, and IrDA connectivity, make it suitable for sensor aggregation and actuator control in a distributed automation node. ## NRND — plan for a migration path Texas Instruments has designated this part as NRND (Not Recommended for New Designs). ## Peripheral set and board integration On-chip brown-out detect, POR, PWM, and a watchdog timer reduce the external BOM count — a clean two-layer board with a 3.3 V regulator and a decoupling cap array is enough to bring the core up. For timing-critical interfaces like UART at higher baud rates, an external source is still advisable.","metaTitle":"Texas Instruments LM3S1601-IBZ50-A2T MCU, 50 MHz","metaDescription":"Texas Instruments LM3S1601-IBZ50-A2T Stellaris ARM Cortex-M3 MCU, 50 MHz, 128 KB flash, 32 KB SRAM, 60 GPIO, -40 to 85°C.
