Frequently Asked Questions
What is the maximum clock frequency of the LM3S3J26-IQR50-C3T and is 16 MHz sufficient for industrial control tasks?
The LM3S3J26-IQR50-C3T runs the ARM Cortex-M3 core at up to 16 MHz, which provides adequate processing throughput for PID control loops, sensor polling, and protocol handling in industrial automation. At 16 MHz, the Cortex-M3 can execute approximately 16 million instructions per second, sufficient for most HVAC controllers, smart metering, and data acquisition nodes running at update rates of 1 kHz or less.
How does the integrated DMA controller benefit sensor data acquisition designs using the LM3S3J26-IQR50-C3T?
The on-chip DMA controller allows ADC conversion results and UART or SPI data streams to transfer directly into memory buffers without halting the Cortex-M3 core. This frees the 16 MHz CPU to process previously acquired data while the DMA simultaneously fills the next buffer, effectively doubling throughput in continuous 12-bit ADC sampling applications compared to interrupt-driven polling schemes.
Which package does the LM3S3J26-IQR50-C3T use and how does it compare to BGA options for industrial PCB assembly?
The LM3S3J26-IQR50-C3T comes in a 64-pin plastic quad flat package (S-PQFP-G64) with exposed leads on all four sides. Unlike BGA packages that require X-ray inspection for solder joint verification, the PQFP's gull-wing leads are fully visible, enabling standard optical inspection and hand-rework during prototype builds — a significant advantage in low-to-medium volume industrial equipment manufacturing.
Is the LM3S3J26-IQR50-C3T approaching end-of-life and should procurement teams look for a migration path?
The LM3S3J26-IQR50-C3T has a YTEOL rating of 0, indicating it is already at or near its product end-of-life horizon. Procurement teams should confirm current stock availability with Texas Instruments authorized distributors and evaluate migration paths to active Tiva C Series or SimpleLink ARM Cortex-M4 microcontrollers, which offer improved performance at 80 MHz or higher with compatible peripheral sets.
