Product details

No new factory orders can be placed.

The core runs at 50 MHz. The 20 KB SRAM and 67 GPIOs are available in the 108-LFBGA package.

Package and temperature: design-in notes

The 108-ball LFBGA (10x10 mm) uses a fine-pitch BGA. Reflow profile should follow MSL 3 guidelines.

Frequently asked questions

Is the LM3S1J11-IBZ50-C3 obsolete?

Yes, Texas Instruments lists the LM3S1J11-IBZ50-C3 as Obsolete.

What is the replacement for LM3S1J11-IBZ50-C3?

No official successor is recorded for the LM3S1J11-IBZ50-C3. A functionally similar part would need to be a Cortex-M3 MCU in a 108-BGA package with at least 128 KB Flash and 20 KB SRAM, but pin compatibility must be verified against the original PCB footprint.
