The 8-channel 10-bit ADC samples analog signals directly, eliminating a separate converter on the board. Built-in brown-out detect, POR, and watchdog timer handle power-sequencing and fault recovery without external supervisor ICs. The internal oscillator runs the core, though an external crystal can be used for tighter timing on the serial ports. ## Supply rails and temperature range The core and I/O share a single 2.25 V to 2.75 V supply rail — a narrow window that demands a regulated 2.5 V rail with ±10 % tolerance. ## NRND lifecycle — planning the BOM line Texas Instruments lists the LM3S1607-IQR50-A0 as NRND (Not Recommended for New Designs). This means the part is still available for existing production but is not intended for new board spins. For sustainment programs already using this MCU, the part remains orderable through independent distribution channels.","metaTitle":"Texas Instruments LM3S1607-IQR50-A0 ARM Cortex-M3 MCU, 50MHz","metaDescription":"Texas Instruments LM3S1607-IQR50-A0 Stellaris ARM Cortex-M3 MCU, 50MHz, 128KB Flash, 32KB RAM, 64-LQFP.
