Frequently Asked Questions
What is the CPU architecture and maximum clock speed of the LM3S9B92-IQC80-C5T?
The LM3S9B92-IQC80-C5T is built on the ARM Cortex-M3 32-bit core and operates at a maximum clock frequency of 16.384 MHz. The Cortex-M3 architecture provides efficient instruction execution with hardware divide, single-cycle multiply, and a Nested Vectored Interrupt Controller (NVIC) for deterministic real-time interrupt handling in embedded control applications.
How many I/O lines does LM3S9B92-IQC80-C5T provide and in which package does it come?
The device provides 65 configurable I/O lines in a 100-pin LQFP (S-PQFP-G100) surface-mount package. The 100-pin LQFP measures approximately 14x14 mm with 0.5 mm pin pitch, giving designers access to the full peripheral set including UART, SPI, I2C, ADC, and DMA channels without requiring a larger BGA package.
For an industrial motor control design, how does the built-in DMA help manage ADC data throughput?
The integrated DMA engine allows ADC conversion results to be transferred directly to memory buffers without CPU intervention, freeing the Cortex-M3 to run control algorithms. At 16.384 MHz with multiple DMA channels, the MCU can sustain continuous ADC sampling across several channels while simultaneously executing PID calculations and updating PWM outputs, a critical capability for multi-axis servo or stepper motor controllers.
Does the LM3S9B92-IQC80-C5T support boundary scan, and how does this benefit production testing?
Yes, the device includes JTAG boundary scan compliant with IEEE 1149.1. This allows automated in-circuit testing of interconnects on assembled PCBs without requiring physical probe access to every pin, significantly reducing test fixture complexity and cutting defect escape rates in high-volume industrial production environments with dense 100-pin LQFP soldering.
