What are the key features of LM3S1P51-IQC80-C1?
- 32-bit ARM Cortex-M3 core at up to 16 MHz with hardware DMA for high-throughput peripheral data transfers
- Integrated multi-channel ADC and 67 programmable I/O lines for rich sensor and actuator interfacing
- 100-pin LQFP package supporting industrial temperature ranges and a broad peripheral set for embedded control designs
What is LM3S1P51-IQC80-C1 used for?
The LM3S1P51-IQC80-C1 is suited for industrial automation, motor drives, building control, and instrumentation systems that demand a deterministic 32-bit real-time processor with multiple analog and digital peripherals. Its DMA engine offloads the Cortex-M3 core during high-rate data transfers between ADC channels and memory, enabling concurrent control loops with minimal latency. The 67 I/O lines in the 100-pin LQFP package give engineers the flexibility to interface sensors, relays, communication buses, and displays without additional I/O expanders.

Frequently Asked Questions
What is the maximum clock speed of the LM3S1P51-IQC80-C1 and how does it compare to other Stellaris devices?
The LM3S1P51-IQC80-C1 runs at up to 16 MHz on its ARM Cortex-M3 core. Higher-end Stellaris LM3S devices reach 80 MHz, so this variant targets cost-optimized control applications where 16 MHz throughput—roughly 16 million instructions per second—is adequate, such as HVAC controllers, simple motor drives, and building automation nodes.
How many I/O lines does the LM3S1P51-IQC80-C1 provide, and which peripheral buses does it support?
The device provides 67 programmable I/O lines across its 100-pin LQFP package. These pins are shared among multiple peripherals including UART, SPI, I2C, and GPIO banks. With DMA support across peripheral channels and an integrated ADC, engineers can simultaneously manage serial communications, analog sampling, and digital control without requiring external interface ICs.
Does the LM3S1P51-IQC80-C1 include an ADC, and what resolution does it offer for sensor signal acquisition?
Yes, the LM3S1P51-IQC80-C1 integrates an on-chip ADC suitable for reading analog sensors directly. The Stellaris LM3S family ADC typically provides 10-bit resolution across multiple input channels, allowing direct connection to temperature sensors, pressure transducers, and potentiometers without an external analog front-end, reducing BOM cost in measurement instruments.
For a compact industrial controller PCB, what board area does the LM3S1P51-IQC80-C1's 100-pin LQFP package require?
The 100-pin LQFP (S-PQFP-G100) package has a standard body size of 14 mm × 14 mm with 0.5 mm lead pitch, occupying approximately 196 mm² of PCB footprint including the pad ring. This fits within a standard eurocard or half-brick module layout, making it practical for DIN-rail industrial controllers and instrument panel inserts with 67 accessible I/O lines.
