Product details

Core parametric and memory budget

The LM3S1J16-IQR50-C5: The 128 KB on-chip flash and 20 KB SRAM leave room for a moderate application stack after the HAL and RTOS overhead.

With 33 general-purpose I/O pins and an 8-channel 10-bit ADC, the device handles mixed-signal control tasks without an external converter. The peripheral set includes DMA, PWM, WDT, and multiple serial interfaces — I²C, SPI, UART/USART, SSI, Microwire, IrDA, and LINbus — covering sensor bridges, motor drivers, and fieldbus adapters in a single package.

Package, supply, and temperature grade

Housed in a 64-LQFP (10x10 mm) surface-mount package, the MCU requires a single supply rail from 1.08 V to 3.6 V.

Texas Instruments has marked the LM3S1J16-IQR50-C5 as obsolete. Sourcing is through independent distribution channels — quantities are confirmed at RFQ, and the available stock carries date codes consistent with the end-of-life window.
