The 0.50 mm pitch demands a 4-layer PCB for reliable fan-out of the 52 I/O lines. ## Peripheral set and analog integration Connectivity includes I²C, SPI, SSI, UART/USART, IrDA, Microwire, and a quadrature encoder interface (QEI) for motor position feedback. An 8-channel 10-bit ADC is on-chip, eliminating the need for an external converter in many sensor-front-end designs. ## Temperature grade and supervisory features On-chip brown-out detect, POR, and a watchdog timer (WDT) provide the supervisory coverage needed for unattended equipment.","metaTitle":"TI LM3S1968-IQC50-A2 ARM Cortex-M3 MCU, 50MHz, 256KB Flash","metaDescription":"Texas Instruments LM3S1968-IQC50-A2 Stellaris ARM Cortex-M3 MCU, 50MHz, 256KB Flash, 64KB RAM, 100-LQFP.
