Product details

What this part is and where it fits

The LM3S1J16-IQR50-C0 is a 32-bit ARM Cortex-M3 MCU from the Stellaris 1000 series, clocked at 50 MHz with 128 KB of Flash and 20 KB of RAM. It includes serial interfaces and an 8-channel 10-bit ADC.

50 MHz Cortex-M3 — what the speed buys you

The ARM Cortex-M3 core runs at 50 MHz. The 20 KB RAM and 128 KB Flash support moderate data buffers and firmware with room for bootloader partitions.

Industrial temperature grade and package

Rated for -40 to 85 °C, this MCU is suited for factory-floor cabinets, outdoor telecom enclosures, and engine-bay-adjacent electronics where the ambient can swing. The 64-LQFP (10x10 mm) package is a standard footprint for mid-density MCUs — easy to hand-solder for prototypes and reflow-friendly for production. Surface-mount only; no through-hole option.

Obsolete — sourcing reality

TI has marked the LM3S1J16-IQR50-C0 as obsolete. No official successor is listed in the lifecycle record. This part is available through independent distribution, sourced and quoted to order against an RFQ.
