The 46 GPIOs and serial interfaces (I²C, SPI, SSI, UART, IrDA) suit it for sensor aggregation, human-machine interface panels, or motor-drive comms in factory-floor equipment. ## NRND — sourcing for existing BOMs through independent channels Texas Instruments lists the LM3S1435-IBZ50-A2 as NRND (Not Recommended for New Designs). This means the part remains available for production builds already qualified, but TI does not target it for new project starts. For existing BOM lines, the part is sourced through independent distribution against an RFQ. Buyers should verify lot date codes and RoHS compliance documentation with the supplier at order placement. ## 108-ball BGA — board integration and layout considerations The 108-LFBGA package measures 10x10 mm with a 0.80 mm ball pitch. This fine-pitch BGA requires a controlled-impedance PCB stack-up, solder-mask-defined pads, and X-ray inspection after reflow. The narrow supply range (2.25 V to 2.75 V) means a 2.5 V regulator with ±10% tolerance is the typical companion; the internal POR and brown-out detect supervise the rail on power-up and during dips. On-chip peripherals include a 2-channel 10-bit ADC, PWM outputs, and a watchdog timer — these reduce external component count for basic analog monitoring and timing tasks.","metaTitle":"LM3S1435-IBZ50-A2 Texas Instruments ARM Cortex-M3 MCU","metaDescription":"Texas Instruments LM3S1435-IBZ50-A2 Stellaris ARM Cortex-M3 MCU, 50 MHz, 96 KB flash, 32 KB RAM, 108-BGA.
