The two 10-bit ADC channels handle analog inputs like potentiometers or current-sense resistors without an external converter. Built-in brown-out detect, POR, PWM, and watchdog timer reduce the need for external supervisory ICs. The internal oscillator saves a crystal on low-cost boards, though an external clock can be used for tighter timing. ## Package and temperature — board-fit realities Housed in a 108-ball BGA (10x10 mm body), the LM3S1162-IBZ50-A2 requires a multi-layer PCB for fan-out — the 0.8 mm ball pitch is manageable with standard 4-layer stack-ups. The 32-bit single-core Cortex-M3 with Thumb-2 instruction set delivers good code density for the 64 KB Flash budget. ## Lifecycle reality — NRND and what that means for procurement Texas Instruments lists the LM3S1162-IBZ50-A2 as NRND (Not Recommended for New Designs). This means it is still available for existing production but is not intended for new projects — the Stellaris family has been superseded by TI's newer Tiva-C and other Cortex-M4 parts. For a BOM that already uses this MCU, we can source it against an RFQ through independent distribution channels. No official pin-compatible replacement is recorded from TI, so a board spin would be needed to migrate to a different part.","metaTitle":"TI LM3S1162-IBZ50-A2 ARM Cortex-M3 MCU, 50MHz, 64KB Flash","metaDescription":"Texas Instruments LM3S1162-IBZ50-A2 Stellaris ARM Cortex-M3 MCU, 50MHz, 64KB Flash, 16KB RAM, 108-BGA.
