Frequently Asked Questions
How many I/O lines does the LM3S5P36-IQR80-C3T provide and how does that compare to smaller 48-pin MCU packages?
The LM3S5P36-IQR80-C3T provides 33 general-purpose I/O lines in a 64-pin LQFP package, offering more connectivity than typical 48-pin Cortex-M3 devices that usually provide 20 to 28 I/O lines, making it a better fit for designs that need to interface with multiple peripherals, displays, or sensor arrays simultaneously.
What role does the DMA controller play in the LM3S5P36-IQR80-C3T for high-throughput sensor data collection?
The LM3S5P36-IQR80-C3T includes DMA channels that can transfer ADC conversion results or SPI/UART data to SRAM buffers without CPU involvement. This allows the 16 MHz Cortex-M3 core to execute control algorithms while DMA independently streams 8-bit or 16-bit data blocks, reducing interrupt overhead and improving system responsiveness.
What PCB height does the LQFP-64 package of LM3S5P36-IQR80-C3T impose on a board stack-up?
The 64-pin LQFP (MS-026BCD) package of the LM3S5P36-IQR80-C3T has a maximum body height of 1.40 mm and a 10 mm × 10 mm body outline with 0.5 mm lead pitch, fitting within standard component height clearances for single-board computers and embedded controllers with enclosure height constraints.
Is the LM3S5P36-IQR80-C3T recommended for new product designs?
The LM3S5P36-IQR80-C3T has a YTEOL value of 0, indicating end-of-life status. Texas Instruments recommends migrating new designs to the Tiva C Series TM4C123 or TM4C129 family, which delivers up to 120 MHz Cortex-M4F performance with hardware floating-point, USB, and Ethernet, replacing the Stellaris LM3S product line.
