Product details

This combination puts it squarely in the mid-range MCU tier: enough processing headroom for motor-control loops, protocol bridging, or sensor fusion, while the Flash and RAM budget fits firmware footprints typical of industrial actuators, building-automation nodes, and portable instrumentation.

No separate extended-temperature variant needed — the same order code covers motor-drive cabinets, outdoor telecom enclosures, and engine-bay modules that see sustained heat soak.

48-VQFN package — footprint and thermal notes

Housed in a 48-VFQFN with exposed pad (supplier package 48-VQFN 7x7 mm).

Listed as Active by the manufacturer. The part remains a valid selection for production builds and new BOMs without a forced migration timeline.

Frequently asked questions

What are the equivalents or cross-references for LM3S808-EGZ50-C2?

Within the Stellaris LM3S800 series, pin-compatible density variants share the same 48-VQFN footprint and peripheral set but differ in Flash and RAM sizes. No single official cross-reference is published for this exact order code; for a second-source evaluation, compare the memory and I/O requirements against the full LM3S800 family to identify a drop-in alternative at a different density tier.

What is LM3S808-EGZ50-C2's listed speed?

The core speed is 50 MHz, driven by the ARM Cortex-M3 pipeline. That is the maximum clock — the PLL and flash wait states must be configured correctly in firmware to run at full speed without bus errors.
