This means Texas Instruments is no longer actively promoting this part for new projects. For existing production, the part remains available through independent distribution on a sourced-to-order basis. Any new BOM should target a pin-compatible or functionally equivalent alternate within the Stellaris family or a current-generation Cortex-M3/M4 from TI or another vendor. Do not lock this into a new design without a qualified second source. ## Memory and peripheral budget for the design The 60 I/O pins and the CAN controller suit a distributed I/O node or motor-drive interface board. The 108-ball LFBGA (10x10 mm) is a fine-pitch BGA requiring a multi-layer PCB with microvias or blind vias for fanout. Brown-out detect and POR are integrated, so an external supervisor is optional unless the system needs a tighter reset threshold.","metaTitle":"Texas Instruments LM3S2601-IBZ50-A2 ARM Cortex-M3 MCU, 50MHz","metaDescription":"Texas Instruments LM3S2601-IBZ50-A2 Stellaris ARM Cortex-M3 MCU, 50MHz, 128KB Flash, 32KB RAM, 60 I/O, CAN/I2C/SPI, -40 to 85°C, 108-BGA.
