It runs on a 1.08 V to 1.32 V core supply, packs 33 general-purpose I/O lines, an 8-channel 10-bit ADC, and a full set of serial interfaces (I²C, SPI, SSI, UART, IrDA, LIN, Microwire). The 64-LQFP package (10x10 mm) and industrial temperature range (-40°C to 85°C) make it a fit for embedded control in factory automation, sensor nodes, and motor-drive auxiliary boards where 50 MHz is enough for the control loop and the 16 KB Flash holds a modest firmware image. Texas Instruments has marked the LM3S1Z16-IQR50-C0T as obsolete. No last-time-buy window or successor part number is on record.","metaTitle":"Texas Instruments LM3S1Z16-IQR50-C0T ARM Cortex-M3 MCU, 50MHz","metaDescription":"Texas Instruments Stellaris LM3S1Z16-IQR50-C0T 32-bit ARM Cortex-M3 MCU, 50MHz, 16KB Flash, 6KB RAM, 64-LQFP, -40°C to 85°C.
