Product details

50 MHz Cortex-M3 with CAN and industrial temperature range

The LM3S2601-IBZ50-A2: This combination suits it for embedded control applications in factory automation, building management, and industrial gateways where CAN connectivity and a moderate processing load are required.

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.

Frequently asked questions

Is the LM3S2601-IBZ50-A2 obsolete?

It is not yet formally discontinued, but TI has signaled that it is on the path to end-of-life. For existing production, the part can be sourced through independent distribution on a quoted-to-order basis. New designs should select a current-production alternate.
