Product details

256 KB Flash and 64 KB SRAM — firmware and data budget

The 256 KB Flash and 64K x 8 SRAM support firmware and data buffers for CAN message queues and Modbus holding registers.

CAN bus and peripheral set — fieldbus ready

The LM3S2918 includes a CANbus controller along with I²C, SPI, SSI, Microwire, IrDA, and two UART/USART interfaces. The 52 general-purpose I/O pins connect local sensors and indicators.

Temperature grade and package — mounting and environment

The 100-LQFP package (14x14 mm) uses a 2.25 V to 2.75 V supply rail.

Obsolete — sourcing reality for this EOL MCU

Texas Instruments has marked the LM3S2918 as obsolete. No official successor part number is published for this order code, and no last-time-buy window remains open.

Frequently asked questions

Is LM3S2918-EQC50-A2 obsolete?

Yes, the LM3S2918-EQC50-A2 is marked as obsolete by Texas Instruments. No last-time-buy window is active, and no official replacement order code has been published.

What is the replacement for LM3S2918-EQC50-A2?

There is no official direct replacement published by the manufacturer. A functionally similar current-production alternative is the TM4C123GH6PM series from the Tiva C family, but pin compatibility in the 100-LQFP package should be verified against the original PCB layout.

Does LM3S2918-EQC50-A2 have CAN bus?

Yes, the LM3S2918 includes a CANbus controller (CAN 2.0B) as part of its connectivity peripheral set, alongside I²C, SPI, UART, and other serial interfaces.
