Product details

The Texas Instruments LM3S812-IGZ50-C2 is a 32-bit ARM Cortex-M3 microcontroller from the Stellaris® family, running at 50 MHz with 64 KB Flash and 8 KB SRAM. The 48-VFQFN exposed-pad package suits compact industrial control boards, sensor hubs, and motor-drive auxiliary controllers where the -40 to 85°C temperature range covers factory-floor and outdoor telecom enclosures.

Package and mounting — VFQFN exposed pad

Store the reels dry — this package is moisture-sensitive and needs baking if the moisture-barrier bag is compromised.
