The LM3S2739-IQC50-A2T: It runs at 50 MHz, providing a deterministic interrupt response typical of the Cortex-M3 pipeline. 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.
