Product details

What this Stellaris MCU brings to an industrial control board

The LM3S8530-IQC50-A2T is a 32-bit ARM Cortex-M3 MCU from the Stellaris 8000 series, clocked at 50 MHz with 96 KB Flash and 64 KB RAM. The 64 KB RAM is notably generous for a Cortex-M3 in this Flash class; it can hold a moderate Ethernet TCP/IP stack plus a CANopen object dictionary without tight buffer management.

Sourcing reality — obsolete, no direct replacement listed

Texas Instruments has marked the LM3S8530-IQC50-A2T as obsolete. If the design is still in development, consider migrating to a currently active Stellaris or Tiva-C family part; a pin-compatible drop-in is not guaranteed, but the peripheral set (Ethernet + CAN) is common across the Stellaris line.

Frequently asked questions

What is the closest pin-compatible alternative to LM3S8530-IQC50-A2T?

No official pin-compatible second source or successor is listed in the lifecycle record. The Stellaris 8000 series shares a common peripheral architecture, so a migration to a currently active Stellaris or Tiva-C part with Ethernet and CAN is the practical route, but pin compatibility must be verified per target part.

What is the core speed of LM3S8530-IQC50-A2T?

The ARM Cortex-M3 core runs at 50 MHz.
