The 108-BGA package (10x10 mm body) brings out 67 GPIOs, plus dedicated pins for the internal oscillator, brown-out reset, DMA, PWM, and watchdog timer. Connectivity covers I²C, SPI, SSI, UART/USART, IrDA, LIN, and Microwire — a broad set for industrial sensor interfaces, motor-drive comms, or simple fieldbus gateways. Texas Instruments has marked the LM3S1J11-IBZ50-C5 as obsolete. Date-code spread and packaging condition (sealed reels or trays) are confirmed at quote time.","metaTitle":"Texas Instruments LM3S1J11-IBZ50-C5 ARM Cortex-M3 MCU, 50MHz","metaDescription":"Texas Instruments LM3S1J11-IBZ50-C5 Stellaris ARM Cortex-M3 MCU, 50MHz, 128KB Flash, 20K RAM, 108-BGA.
