Two 10-bit ADC channels are integrated, enough for one or two analog feedback signals without an external converter. The internal oscillator means you can boot without a crystal, though a precision clock improves timing for baud-rate generation. The 46 I/O lines in a 108-LFBGA package mean many pins are shared with alternate functions — the BGA ball map needs careful routing to avoid signal conflicts on shared pads. ## NRND status — plan the replacement now TI lists the product status as NRND. No last-time-buy date is published in the record. ## BGA assembly and rework notes The 108-BGA (10x10 mm) package has a 0.8 mm ball pitch typical for this density. That is hand-solderable with a hot-air station and stencil, but the inner balls are hard to inspect without X-ray. The board needs a via-in-pad or microvia strategy for the center balls to escape to inner layers.","metaTitle":"TI LM3S1162-IBZ50-A2T ARM Cortex-M3 MCU, 50MHz, 64KB Flash","metaDescription":"Texas Instruments LM3S1162-IBZ50-A2T Stellaris 32-bit ARM Cortex-M3 MCU at 50MHz with 64KB Flash, 16KB RAM, 46 I/O, 108-BGA.
