Product details

Cortex-M3 with Ethernet and CAN in a 100-pin LQFP

The LM3S8962-EQC50-A2T is a Stellaris ARM Cortex-M3 MCU from Texas Instruments, built around a 32-bit single-core processor running at 50 MHz.

The 256 KB Flash is sized to hold a TCP/IP stack plus a real-time control loop, while the 64 KB SRAM provides enough buffer space for Ethernet frames and CAN message objects. If your firmware image already exceeds 256 KB, this part will not fit without code compression or external memory — plan accordingly.

The only channel for procurement is the independent surplus market.

Ethernet and CAN — the two peripherals that define the part

The integrated Ethernet MAC and CAN 2.0 controller are the features that set this MCU apart from simpler Stellaris siblings. If your board needs both a wired network connection and a fieldbus interface without external PHY or CAN transceiver (the PHY is external, but the MAC is on-chip), this part was designed for exactly that combination. The 42 GPIOs and four 10-bit ADC channels round out the peripheral set for sensor and actuator control.

Frequently asked questions

Is LM3S8962-EQC50-A2T obsolete?

Yes, the LM3S8962-EQC50-A2T is officially marked Obsolete. Texas Instruments has discontinued production, and no last-time-buy window remains active. The only procurement path is through the independent surplus market.

What are the best replacements for LM3S8962-EQC50-A2T?

Texas Instruments does not list a direct pin-compatible successor for the LM3S8962-EQC50-A2T. For a similar Stellaris Cortex-M3 with Ethernet and CAN, look at the TM4C series (e.g., TM4C129x) which offers higher performance and more memory, but requires a board respin due to different package and pinout. No drop-in replacement is available from TI.

Does LM3S8962-EQC50-A2T support Ethernet?

Yes, it includes an integrated Ethernet MAC controller. An external PHY chip is required to connect to an RJ45 jack. The CAN controller is also on-chip, making this MCU suitable for industrial networking applications.
