Frequently Asked Questions
What is the maximum CPU clock frequency of the LM3S1850-IQC50-A2T and how does it affect real-time control tasks?
The LM3S1850-IQC50-A2T runs at up to 50 MHz on its ARM Cortex-M3 core, delivering up to 50 DMIPS of integer performance. This frequency is sufficient for deterministic PID control loops executing in under 20 µs, making the device a practical choice for servo drives and industrial sensor polling applications where cycle-accurate timing is required.
How many I/O lines does the LM3S1850-IQC50-A2T provide, and can they interface directly with 3.3 V sensors?
The device provides 56 GPIO lines, all operating at 3.3 V logic levels. Each pin can source or sink up to 2 mA with configurable pull-up or pull-down resistors. This allows direct connection to 3.3 V MEMS sensors, digital encoders, or relay drivers without additional level-shifting hardware in typical 3.3 V system designs.
For a compact motor-controller board, what board area does the 100-pin LQFP package of LM3S1850-IQC50-A2T require?
The 100-pin LQFP (JESD-30 code S-PQFP-G100) measures 14 mm x 14 mm body with 0.5 mm pin pitch, occupying approximately 196 mm² of PCB footprint. This compact form factor, combined with 56 I/O pins and on-chip ADC, allows a full motor-control solution to fit on a board smaller than 50 mm x 80 mm when standard peripheral components are placed around it.
