The 108-BGA package (10x10 mm) means the 0.50 mm pitch ball array demands a 4-layer PCB for fan-out — two-layer boards will struggle to route the inner rows. ## Lifecycle reality — obsolete, no direct successor Texas Instruments lists this part as Obsolete. For a BOM line that depends on this MCU, the supply path runs through independent surplus channels — quantities are lot-specific and confirmed at RFQ.","metaTitle":"Texas Instruments LM3S1J11-IBZ50-C3T","metaDescription":"Texas Instruments Stellaris LM3S1J11-IBZ50-C3T ARM Cortex-M3 MCU, 50MHz, 128KB Flash, 20K RAM, 108-BGA.
