The device is supplied in a 100-pin LQFP package (14x14 mm body), surface-mount, with 56 general-purpose I/O lines brought out. ## Peripheral set for industrial control The connectivity peripheral set includes CAN, I²C, SPI, SSI, UART, and IrDA — the CAN 2.0B controller is the key differentiator for industrial bus networks, allowing direct connection to a CANopen or DeviceNet segment without an external CAN controller. On-chip supervisory peripherals — brown-out detect, POR, and a watchdog timer — provide the system-level reset and fault monitoring that keeps the MCU from locking up in noisy industrial environments. ## Industrial temperature qualification This qualifies the part for deployment in factory-floor enclosures, outdoor telecom cabinets, and engine-bay-adjacent modules where the ambient temperature cycles across the full range. Texas Instruments has designated the LM3S2739-IQC50-A2T as NRND (Not Recommended for New Designs). Existing production builds can continue to source the part through independent distribution channels; new designs should evaluate the recommended migration path from TI for the Stellaris portfolio. No stock-holding claim is made; each order is sourced through our multi-supplier network.","metaTitle":"Texas Instruments LM3S2739-IQC50-A2T ARM Cortex-M3, 50MHz","metaDescription":"Texas Instruments LM3S2739-IQC50-A2T Stellaris ARM Cortex-M3 MCU, 50MHz, 128KB Flash, 64KB RAM, industrial temp, NRND.
