The LM3S1N16-IQR50-C1: The 50 MHz clock rate is typical for a mid-range Cortex-M3, adequate for motor-control loops, protocol bridging, and data-logging tasks that don't require heavy DSP. The 64 KB Flash and 12 KB RAM limit firmware to moderate code size — think a single protocol stack plus application logic, not a full RTOS with multiple stacks. If your firmware footprint exceeds this, you'll need to step up to a higher-density Stellaris variant or a different family entirely. Connectivity includes I2C, SPI, UART/USART, LIN, IrDA, and Microwire, which covers most industrial sensor and actuator buses. The 8-channel 10-bit ADC is sufficient for basic analog sensing but not high-resolution measurement.
Obsolete — sourcing strategy for the LM3S1N16-IQR50-C1
The LM3S1N16-IQR50-C1 is listed as obsolete. For existing BOM lines, the only supply channel is the surplus and independent distribution market.
Housed in a 64-pin LQFP with a 10x10 mm body, the LM3S1N16-IQR50-C1 is a surface-mount device.
