Product details

The Texas Instruments LM3S6110-EQC25-A2 is a 32-bit ARM Cortex-M3 microcontroller from the Stellaris 6000 series, clocked at 25 MHz. The on-chip Ethernet MAC makes this part a natural fit for industrial gateways, remote terminal units, or any control node that needs a direct twisted-pair link without an external MAC chip.

The 25 MHz Cortex-M3 core handles protocol parsing and Modbus TCP bridging. The Ethernet MAC saves an external MAC chip and PCB area.

The chip includes UART/USART, SPI, SSI, Microwire, and IrDA serial interfaces.

Frequently asked questions

What is the replacement for LM3S6110-EQC25-A2?

Texas Instruments has not published an official direct replacement for this exact order code. Pin-compatible Stellaris siblings with larger memory exist, but for new designs a board respin to the TM4C12x series (Cortex-M4F) or an STM32F107 with Ethernet is recommended.

Does LM3S6110-EQC25-A2 have Ethernet?

Yes, the LM3S6110-EQC25-A2 includes an integrated Ethernet MAC controller, supporting MII and RMII interfaces for direct connection to an external PHY.

What is the clock speed of LM3S6110-EQC25-A2?

The LM3S6110-EQC25-A2 runs at 25 MHz, driven by an ARM Cortex-M3 core.

What is the package of LM3S6110-EQC25-A2?

The LM3S6110-EQC25-A2 is supplied in a 100-pin LQFP package (14x14 mm body) with 0.5 mm pitch, suitable for surface-mount assembly.
