Product details
Frequently asked questions
What is the closest pin-compatible alternative to LM3S8730-IQC50-A2?
No official TI successor with identical Ethernet, CAN, and 100-LQFP footprint is listed. Any replacement would require validating pin compatibility and peripheral set against the original Stellaris family documentation.
What is LM3S8730-IQC50-A2's core speed?
The ARM Cortex-M3 core runs at 50 MHz, which provides enough throughput for protocol bridging between Ethernet and CAN while handling local I/O control.
What compliance documentation is available for LM3S8730-IQC50-A2?
The part is listed with a base product number LM3S8730. Compliance documentation such as RoHS and REACH declarations would be provided with the shipment; specific certificates can be requested at quote time.
