The brown-out detect and POR supervisor reduce external reset-IC cost. The WDT is there for safety-critical loops — enable it early in firmware bring-up to catch runaway code during development. The LM3S6432-IBZ50-A2 is officially obsolete. No last-time-buy window remains from the manufacturer. If your design can tolerate a pin-compatible migration, the Stellaris family includes other Cortex-M3 variants in the same 108-BGA footprint; verify the exact memory and peripheral set against your firmware image.","metaTitle":"LM3S6432-IBZ50-A2 Stellaris ARM Cortex-M3 MCU, 50MHz","metaDescription":"LM3S6432-IBZ50-A2 Stellaris ARM Cortex-M3 MCU, 50MHz core, 96KB Flash, 32KB RAM, Ethernet, 108-BGA.
