That Flash-to-SRAM ratio is typical for a control-oriented MCU — the firmware fits the application stack and a moderate communication library, but leaves headroom for field-upgradeable parameter tables. The 32-bit Cortex-M3 core at this speed delivers deterministic interrupt latency for time-critical loops like PWM generation or sensor polling. ## Serial connectivity and ADC – sizing the peripheral mix The two 10-bit ADC channels are adequate for single-ended analog inputs like potentiometer feedback or temperature monitoring; for more channels or higher resolution, an external ADC would be needed. Brown-out detect, POR, PWM, and WDT are integrated, reducing external supervisor IC count. ## NRND status – procurement posture and migration planning For new designs, a pin-compatible successor in the same Stellaris family should be evaluated — the 100-LQFP footprint and 2.25 V to 2.75 V supply rail are common across the series, so migration may be a firmware re-spin rather than a board respin. ## Package and temperature grade – board-fit checklist Housed in a 100-LQFP with a 14×14 mm body, the 0.50 mm pitch demands a controlled impedance board stack — a 4-layer PCB is the practical minimum for fan-out of all 46 I/O plus supply and ground. Supply voltage is 2.25 V to 2.75 V — a tight window that calls for a regulated rail; do not feed this from an unregulated battery or a 3.3 V bus without a low-dropout regulator.","metaTitle":"LM3S1435-IQC50-A2T – Texas Instruments ARM Cortex-M3 MCU","metaDescription":"LM3S1435-IQC50-A2T – TI Stellaris ARM Cortex-M3, 50 MHz, 96 KB Flash, 32 KB SRAM, SPI/I2C/UART, 2×10b ADC, 100-LQFP, -40°C to 85°C, NRND.
