Product details

The LM3S8530-IQC50-A2: This part is officially obsolete per the manufacturer's lifecycle status. Texas Instruments no longer accepts orders; available stock is through independent distribution channels.

50 MHz Cortex-M3 — what the speed rating delivers

The 50 MHz core clock handles a TCP/IP stack for Ethernet communication and a CANopen stack for fieldbus, with cycles left for a PID control loop. The 96 KB Flash is the firmware ceiling; the 64 KB SRAM handles packet buffers and moderate data logging.

Frequently asked questions

Is the LM3S8530-IQC50-A2 obsolete?

Yes, the LM3S8530-IQC50-A2 is officially obsolete. The only available supply is through independent distributors sourcing verified surplus and new-old-stock inventory. Every unit we quote is inspected for marking and date-code consistency before shipment.

What is a direct replacement for LM3S8530-IQC50-A2?

The official manufacturer successor for this part is not listed in the available records. For a pin-compatible drop-in, the closest candidates are other Stellaris LM3S8000-series MCUs with the same 100-LQFP footprint, but each variant differs in Flash size, SRAM, and peripheral set. A parametric search against the 50 MHz core, Ethernet + CAN, and 100-pin package is the best approach to identify a functional replacement. We can assist with cross-referencing against available stock on a quote request.

Where can I purchase the LM3S8530-IQC50-A2?

We can quote it against an RFQ with confirmed availability and current pricing at the time of your request. Because the supply is limited to verified surplus and new-old-stock, availability varies — a quick quote request is the most reliable way to check current inventory and lead time.
