Frequently Asked Questions
How many I/O lines does the LM3S1P51-IQC80-C1T provide, and which on-chip peripherals support analog measurement?
The LM3S1P51-IQC80-C1T provides 67 I/O lines and includes an on-chip ADC for direct analog signal acquisition. The DMA controller offloads ADC result transfers to memory, allowing continuous 12-bit sampling without CPU intervention. This combination supports multi-channel sensor monitoring in industrial data-logging and process-control applications running on the 32-bit ARM Cortex-M3 core.
What package does the LM3S1P51-IQC80-C1T use, and how does it suit high I/O count PCB designs?
The LM3S1P51-IQC80-C1T comes in a 100-pin PQFP (S-PQFP-G100) package. The 100-pin perimeter layout exposes all 67 I/O lines plus power and ground pins with a 0.5 mm lead pitch, making it accessible for standard SMT soldering and suitable for boards needing dense peripheral connectivity without BGA infrastructure. This package is also compatible with common ICT bed-of-nails fixtures.
When would the LM3S1P51-IQC80-C1T be selected over a smaller ARM Cortex-M3 device for a motor-control design?
A motor-control design requiring simultaneous PWM outputs, encoder feedback (multiple digital inputs), and analog current sensing across 3 phases benefits from the LM3S1P51's 67 I/O lines and integrated ADC channels. Smaller 48-pin or 64-pin ARM Cortex-M3 parts would exhaust their I/O before accommodating all control, feedback, and communication signals, whereas the 100-pin LM3S1P51 handles the full signal set within a single chip.
