Core and memory — fit for a 32-bit control application
The LM3S1C58-IQC80-A1T: The part is built around an ARM Cortex-M3 core, a 32-bit single-core processor running at 80 MHz. This clock rate, paired with 512 KB of on-chip Flash program memory and 64 KB of SRAM, provides enough headroom for a moderately complex control loop or communications stack without external memory. The 512 KB Flash is arranged as 512K x 8, and the 64 KB RAM as 64K x 8, giving a clear picture of the memory map for firmware sizing.
Connectivity and peripherals — serial bus coverage
The connectivity set includes I²C, IrDA, LINbus, Microwire, SPI, SSI, and UART/USART. This covers most common serial interfaces for sensor fusion, motor drive feedback, or industrial fieldbus adaptation. The 60 general-purpose I/O pins allow parallel interfacing to displays or memory-mapped peripherals. On-chip data converters include a 16-channel, 12-bit ADC, suitable for reading multiple analog sensor inputs without an external multiplexer.
Package and supply — board integration
The device is supplied in a 100-pin LQFP package with a 14x14 mm body. The part includes brown-out detect, POR, PWM, and WDT peripherals for robust operation in noisy or power-cycled applications.
