Product details

The Texas Instruments LM3S2601-IQC50-A2T is a 32-bit ARM Cortex-M3 MCU from the Stellaris® 2000 series, clocked at 50 MHz with 128 KB Flash and 32 KB RAM. It carries CAN, I²C, SPI, SSI, UART, and IrDA interfaces, plus a PWM unit and brown-out/POR supervisor — a typical fit for a CAN-based industrial controller, sensor hub, or motor-drive node that needs one protocol stack and a handful of analog or digital I/O.

NRND — plan the BOM line accordingly

That means TI has stopped actively promoting it for new projects, though it may still be available for existing production runs through the independent channel.

Frequently asked questions

How do I get current pricing and availability for LM3S2601-IQC50-A2T?

Submit an RFQ through this listing. Availability and current pricing are confirmed at quote time through our independent sourcing network. No stock or price figures are published here because the channel fluctuates for NRND parts.

What is the closest pin-compatible alternative to LM3S2601-IQC50-A2T?

No official successor is listed in the lifecycle record. However, the Stellaris LM3S family shares the same 100-LQFP footprint and peripheral set across many density options (e.g., LM3S2965 with 256 KB Flash). A migration within the family is typically a firmware recompile and a BOM swap. For a current-design recommendation, contact our sourcing team with your firmware requirements.

What is LM3S2601-IQC50-A2T's listed speed?

The core runs at 50 MHz. That is the maximum clock for the ARM Cortex-M3 on this part, delivering roughly 62.5 MIPS — adequate for a single CANopen node with a 1 ms cycle and a PID loop.

What compliance documentation does this brand provide for LM3S2601-IQC50-A2T?

Texas Instruments provides RoHS and REACH compliance documentation for this part. The 100-LQFP package is lead-free and compatible with standard reflow profiles. No UL or IEC certification is listed in the component record; check the TI product page for the latest compliance certificates.
