The 52 general-purpose I/O lines break out through a 100-pin LQFP (14x14 mm body) — the 0.5 mm pitch demands a controlled-impedance stack-up on the PCB for the higher-speed peripherals. ## Peripheral set: CAN, multiple serial interfaces, 8-channel 10-bit ADC Connectivity includes CANbus, I²C, IrDA, Microwire, SPI, SSI, and UART/USART — the CAN 2.0B controller with message filtering is the main draw for industrial fieldbus nodes. The 8-channel 10-bit A/D converter samples at rates adequate for slow-loop sensor feedback, not high-speed acquisition. ## Industrial temperature grade, internal oscillator Operating temperature range covers -40°C to 85°C (TA) — this is the industrial band, suitable for factory-floor controllers, HVAC, and outdoor telecom enclosures that see thermal cycling. The internal oscillator eliminates an external crystal for the core clock, though the CAN and USB timing may still need an external resonator for bit-rate accuracy.","metaTitle":"Texas Instruments LM3S2948-IQC50-A2T MCU, 50MHz, 256KB Flash","metaDescription":"Texas Instruments LM3S2948-IQC50-A2T Stellaris ARM Cortex-M3 MCU, 50MHz, 256KB Flash, 64KB RAM, NRND lifecycle.
