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.","metaTitle":"TI LM3S1J16-IQR50-C0 Stellaris Cortex-M3 MCU, 50 MHz","metaDescription":"Obsolete TI Stellaris LM3S1J16-IQR50-C0 ARM Cortex-M3 MCU, 50 MHz, 128 KB Flash, 20 KB RAM, -40 to 85°C.
