Product details

It targets cost-sensitive embedded control applications — motor drives, industrial sensors, human-machine interfaces — where the Cortex-M3 core handles deterministic interrupt response and the peripheral set covers the common control-loop needs: PWM, quadrature encoder interface (QEI), and a 6-channel 10-bit ADC.

Memory and peripheral fit for a BOM line

Brown-out reset and POR are integrated, so external supervisor ICs can be dropped from the BOM in non-critical designs.

Package and rework — 48-VFQFN exposed pad

It reworks cleanly with hot air if the pad is properly tinned and the board has a solder-mask-defined pad. The tray shipping means no tape-and-reel handling fee for prototype quantities.

Listed as active in the manufacturer's product status. No pin-compatible second source is documented in the Stellaris 600 family, so the BOM carries single-source risk — plan a qualification gate if volume ramps.

Frequently asked questions

What is the maximum speed of LM3S618-IGZ50-C2?

The core runs at 50 MHz. That's the maximum clock from the internal oscillator or an external source; the flash needs zero wait states at this speed, so instruction fetch doesn't stall.

How many I/O pins does LM3S618-IGZ50-C2 have?

30 general-purpose I/O pins are available on the 48-VFQFN package. Some are shared with the ADC and serial interfaces, so the usable count depends on which peripherals are enabled.
