Product details

Texas Instruments has ended production of this Stellaris ARM Cortex-M3 MCU, and it is no longer recommended for new designs. Buyers needing this exact order code for field repair, BOM maintenance, or legacy production runs can source it through independent distribution channels.

108-ball BGA — layout and assembly considerations

The 108-LFBGA package (10x10 mm body) is a compact footprint. The 34 I/O count is modest for a BGA of this ball count — many balls are dedicated to power, ground, and the Ethernet PHY interface.

Frequently asked questions

Is LM3S8930-IBZ50-A2 discontinued?

Yes, the LM3S8930-IBZ50-A2 is listed as Obsolete. Texas Instruments no longer manufactures this Stellaris MCU. It is not recommended for new designs.

What is the replacement for LM3S8930-IBZ50-A2?

The evidence does not list an official TI successor part number for the LM3S8930-IBZ50-A2. TI's Stellaris family was superseded by the Tiva C Series ARM Cortex-M4F devices, but pin compatibility and exact functional equivalence are not documented in the available records. For a drop-in replacement, the best approach is to compare the 108-BGA footprint, 50 MHz core, and Ethernet+CAN peripheral set against current TI Tiva or other ARM Cortex-M MCUs in a 10x10 BGA package.
