Frequently asked questions
What is the speed rating of this MCU?
The LM3S1165-IBZ50-A2T is rated for 50MHz operation, implemented on an ARM Cortex-M3 single-core architecture.
What are the memory specifications?
Program memory is 64KB of Flash; RAM is 16K×8. This is the entry-density configuration of the Stellaris 1000 series — adequate for basic industrial MCU firmware but not for memory-intensive applications.
How do I source this part given its NRND status?
The LM3S1165-IBZ50-A2T is sourced to order against an RFQ. Current supply comes from independent channel and broker inventory; availability is episodic and pricing follows allocation logic rather than volume-discount schedules. Quantities, lead times, and pricing are quoted on request.
