Product details

50 MHz Cortex-M3 — what the core speed buys you

The LM3S615-EGZ50-C2: The 50 MHz ARM Cortex-M3 core runs at 50 MHz. The 32 KB Flash and 8 KB SRAM support moderate data buffers and stack depth.

The internal oscillator is accurate enough for UART communication at standard baud rates, but for CAN or precise timing you will want an external crystal.

On-chip peripherals and connectivity

Serial connectivity covers I²C, SPI, SSI, Microwire, and UART/USART, which handles most industrial sensor buses and debug consoles.

Frequently asked questions

Is LM3S615-EGZ50-C2 a direct replacement for LM3S615-EGZ50-C1?

The evidence does not list a direct cross-reference between the -C2 and -C1 suffix variants. Typically, the suffix change indicates a revision or manufacturing site change. Verify pin compatibility and any electrical differences against the respective datasheet revision tables before substituting in a production BOM.

What is the closest pin-compatible alternative in the Stellaris 600 family?

The LM3S615-EGZ50-C2 is a specific density and speed variant in the Stellaris 600 series. Pin-compatible alternatives exist across the LM3S600 family with different Flash/SRAM sizes and peripheral sets, but the evidence does not list a specific alternate order code. For dual-sourcing, contact TI for their recommended second-source matrix within the series.
