Product details

The LM3S8962-IBZ50-A2T: 32-bit ARM Cortex-M3 MCU from the Stellaris 8000 series, clocked at 50 MHz. Integrates 256 KB Flash and 64 KB SRAM.

At 50 MHz the Cortex-M3 core executes a single-cycle multiply and a hardware divide, which keeps PID loops and protocol stacks (TCP/IP, CANopen) within a deterministic window. The combination of Ethernet and CAN on one die means this part can serve as a gateway node between a plant-floor CAN bus and a higher-level Ethernet network without an external bridge chip.

The LM3S8962-IBZ50-A2T is marked obsolete by the manufacturer. No official replacement part number has been issued.

Frequently asked questions

What is the replacement for LM3S8962-IBZ50-A2T?

Texas Instruments has not published a direct pin-compatible replacement for this Stellaris part. The TM4C series is the architectural successor but requires a board respin. For an exact drop-in, the only option is to source the original LM3S8962-IBZ50-A2T through surplus channels.
