Frequently Asked Questions

What processor core and maximum clock speed does the LM3S5P56-IQR80-C3T use?

The LM3S5P56-IQR80-C3T is based on the 32-bit ARM Cortex-M3 processor core and operates at a maximum clock frequency of 16 MHz. The Cortex-M3 architecture provides deterministic interrupt latency and hardware multiply/divide support, making it well suited for real-time embedded control applications.

What on-chip peripherals does the LM3S5P56-IQR80-C3T include?

The LM3S5P56-IQR80-C3T integrates an ADC for analog signal measurement, DMA channels for memory-to-peripheral data transfers without CPU intervention, and PWM channels for motor control or power conversion. It also provides 33 GPIO lines for flexible digital I/O connectivity across multiple peripherals and interfaces.

What package does the LM3S5P56-IQR80-C3T use?

This microcontroller is packaged in a 64-pin plastic quad flat package (JESD-30 code S-PQFP-G64). The QFP package provides all-side lead access for signal routing on standard multilayer PCBs and is compatible with lead-free reflow solder assembly as indicated by the Pb-free designation.

Is the LM3S5P56-IQR80-C3T still in active production?

The YTEOL value of 0 for this part suggests it may be at or near end-of-life status. Designers starting new projects should verify current availability and lifecycle status with Texas Instruments or authorized distributors. For long-term production programs, migrating to a currently active Tiva C Series or SimpleLink MCU is recommended.

What are the primary application areas for the LM3S5P56-IQR80-C3T?

This 32-bit microcontroller targets industrial control panels, smart metering, building automation, and motor drive applications that benefit from the ARM Cortex-M3 architecture combined with on-chip ADC, DMA, and PWM. Its 33 GPIO lines and 64-pin QFP package suit mid-complexity embedded designs requiring multiple sensor and actuator interfaces without the overhead of a larger processor platform.
