Frequently Asked Questions
What is the maximum CPU clock frequency of LM3S617-IQN50-C2 and how does it compare to other LM3S devices?
The LM3S617-IQN50-C2 operates at a maximum clock frequency of 32 MHz using its ARM Cortex-M3 core, which delivers up to 32 MIPS of fixed-point throughput for deterministic control loops. This places it in the lower-frequency segment of the LM3S family, making it a cost-effective choice versus higher-clocked 50 MHz or 80 MHz LM3S variants when processing requirements do not demand maximum speed.
Does LM3S617-IQN50-C2 include an ADC, and what sensor interface scenarios does that enable?
Yes, the LM3S617-IQN50-C2 integrates an on-chip ADC, allowing it to directly digitize analog sensor signals such as temperature (0 V to 3.3 V range), pressure transducers, or current-sense resistors without an external ADC IC. This integration reduces BOM cost by at least 1 component and simplifies routing, making the device well-suited for thermostat, flow-meter, and light industrial sensor-fusion applications.
How does the 48-pin LQFP package influence PCB layout for the LM3S617-IQN50-C2?
The 48-pin LQFP (MS-026BBC) package has a 0.5 mm pin pitch and a 7 mm × 7 mm body, providing a compact footprint that fits on a 2-layer or 4-layer PCB with standard SMT reflow assembly. Its peripheral pin arrangement on all 4 sides facilitates short trace routing to decoupling capacitors and GPIO peripherals, which is important for signal integrity at 32 MHz operation.
Is LM3S617-IQN50-C2 still in active production, and what should designers consider for long-term supply?
The LM3S617-IQN50-C2 has a YTEOL of 0, indicating it may be at or near end-of-life status, so designers starting new 32-bit Cortex-M3 designs should evaluate the TM4C series or MSP432 as pin-compatible or functionally equivalent successors with longer product lifecycle. Existing designs requiring this exact part should secure buffer stock, as distributor inventory levels may decline; typical automotive or industrial programs plan for at least 5-year supply coverage.
