For legacy BOM lines already using this MCU, the NRND status means you should secure last-time-buy quantities or validate a drop-in replacement before the official EOL notice arrives. The LM3S1538 includes a Brown-out Detect, POR, PWM, and WDT — the usual supervisory blocks for a standalone embedded controller. On the communication side, it supports I²C, IrDA, Microwire, QEI, SPI, SSI, and UART/USART. That is a practical mix for motor-control feedback (QEI for encoder inputs), sensor aggregation (I²C/SPI), and serial debug or fieldbus links (UART).","metaTitle":"LM3S1538-IBZ50-A2 Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"LM3S1538-IBZ50-A2 32-bit ARM Cortex-M3 MCU from the Stellaris series. 50 MHz core, 96 KB Flash, 64 KB SRAM, 43 I/Os, 8x10-bit ADC.
