Product details

The LM3S1Z16-IQR50-C0T is a Texas Instruments Stellaris-series 32-bit ARM Cortex-M3 MCU clocked at 50 MHz, with 16 KB of Flash program memory and 6 KB of SRAM. It runs on a 1.08 V to 1.32 V core supply, packs 33 general-purpose I/O lines, an 8-channel 10-bit ADC, and a full set of serial interfaces (I²C, SPI, SSI, UART, IrDA, LIN, Microwire). The 64-LQFP package (10x10 mm) and industrial temperature range (-40°C to 85°C) make it a fit for embedded control in factory automation, sensor nodes, and motor-drive auxiliary boards where 50 MHz is enough for the control loop and the 16 KB Flash holds a modest firmware image.

Texas Instruments has marked the LM3S1Z16-IQR50-C0T as obsolete. No last-time-buy window or successor part number is on record.

Frequently asked questions

What is LM3S1Z16-IQR50-C0T's listed speed?

The core runs at 50 MHz, which is the maximum clock for this ARM Cortex-M3 implementation in the Stellaris family. That speed is adequate for control loops, serial protocol handling, and moderate data processing.

How do I get current pricing and availability for LM3S1Z16-IQR50-C0T?
