Product details

The LM3S2601-EQC50-A2 is a 32-bit ARM Cortex-M3 MCU from Texas Instruments' Stellaris series. The 50 MHz core handles motor drives, industrial I/O nodes, and sensor fusion tasks. 128 KB of Flash and 32K x 8 RAM support a CANopen slave node or multi-axis stepper controller. The part includes a full set of peripherals: brown-out detect, POR, PWM, and WDT for watchdog supervision.

Industrial temperature grade — rated for harsh environments

Supply range is 2.25 V to 2.75 V.

No official TI successor part number is listed for this order code. For legacy production, the surplus channel is the practical route.

Frequently asked questions

What is the replacement for LM3S2601-EQC50-A2?

No official TI replacement part number is published for this order code. For new designs, consider TI's TM4C series Cortex-M4 MCUs as a functional upgrade, but verify pin-compatibility and peripheral mapping against your layout.

What is the pinout of LM3S2601-EQC50-A2?

The LM3S2601-EQC50-A2 uses a 100-LQFP package (14x14 mm) with 60 general-purpose I/O. The full pinout is in the Texas Instruments datasheet for the Stellaris LM3S2601.

What is LM3S2601-EQC50-A2's core speed?

The LM3S2601-EQC50-A2 runs at 50 MHz on a 32-bit ARM Cortex-M3 core.
