Product details

At 50 MHz, the Cortex-M3 core handles real-time control loops such as motor commutation, sensor fusion, or protocol bridging. The single-cycle multiply and hardware divide keep interrupt latency predictable.

Memory sizing: 64 KB Flash, 8 KB RAM

64 KB of Flash suits firmware images for a single control algorithm plus a modest bootloader. 8 KB of RAM handles stack, UART buffers, and ADC conversion tables.

The LM3S818-EGZ50-C2 is marked with an EOL hot lifecycle stage, meaning it is approaching end-of-life or in last-time-buy status.

Frequently asked questions

What is the closest pin-compatible alternative to LM3S818-EGZ50-C2?

Within the Stellaris ARM Cortex-M3 family, parts with the same 48-VQFN footprint and similar peripheral set (e.g., LM3S811 or LM3S828) may be pin-compatible. Verify the specific memory and ADC configuration against your firmware requirements before substituting.

What is LM3S818-EGZ50-C2's listed speed?

The core runs at 50 MHz, which is the maximum clock for this Cortex-M3 implementation in the Stellaris series.
