Frequently Asked Questions
What is the maximum clock frequency of the LM3S2D93 and how does it affect real-time task scheduling?
The LM3S2D93-IQC80-A2 runs its ARM Cortex-M3 core at up to 16.384 MHz, providing deterministic interrupt latency of a few clock cycles that suits RTOS-based real-time scheduling. At 16.384 MHz the device can execute approximately 16 million instructions per second, sufficient for PID motor-control loops, UART communication at 115200 baud, and periodic ADC sampling at several kilosamples per second.
How does the integrated DMA support high-throughput ADC data collection in an industrial sensor application?
The onboard DMA controller transfers ADC conversion results directly to RAM without CPU intervention, allowing the Cortex-M3 core to continue executing control code while 12-bit samples accumulate in a buffer. This parallel operation is critical in vibration analysis or multi-channel data acquisition where the ADC must run at its maximum sample rate while the processor simultaneously filters and transmits results over UART or SPI.
For a new design today, is the LM3S2D93 still a viable choice or should an alternative Cortex-M4 device be considered?
The YTEOL score of 0 indicates this part may be approaching end-of-life, so new designs should evaluate current TI Tiva C Series or ARM Cortex-M4 devices such as TM4C123 which offer higher clock speeds above 80 MHz, more peripherals, and longer supply availability. Existing designs already using the LM3S2D93 in the 100-pin LQFP footprint can continue procurement but should plan a migration path within 2 to 3 product cycles.
Does the 100-pin LQFP package of the LM3S2D93 support JTAG boundary scan for automated board testing?
Yes, the LM3S2D93-IQC80-A2 includes JTAG boundary scan support per the JESD-30 code S-PQFP-G100 designation, enabling automated in-circuit testing of solder joints on the 100-pin LQFP package. Boundary scan chains allow test equipment to verify pin connectivity without physical probes, which is especially valuable in dense PCB assemblies where the 0.5 mm pitch LQFP pads are difficult to access with flying-probe fixtures.
