Product details

The LM3S601-IQN50-C2: It is built for industrial-control and sensor-interface tasks where a moderate processing load and a rich peripheral set are needed in a compact 48-pin LQFP package.

The brown-out detect and POR circuits protect against supply glitches in noisy industrial environments, while the PWM and watchdog timer support simple motor-drive and fail-safe supervision without an external supervisor IC.

Obsolete — sourcing reality for sustainment programs

The LM3S601-IQN50-C2 is obsolete per the lifecycle record.

Frequently asked questions

What is the replacement for LM3S601-IQN50-C2?

No official successor is documented in the lifecycle record. The LM3S611 is a pin-compatible sibling within the same Stellaris 600 family and 48-LQFP package, but it carries a larger memory configuration — firmware and peripheral validation are required before substituting it into an existing design.
