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.","metaTitle":"Texas Instruments LM3S1C58-IQC80-A1T Stellaris MCU, 80MHz","metaDescription":"Texas Instruments LM3S1C58-IQC80-A1T Stellaris ARM Cortex-M3 MCU, 512KB Flash, 64KB RAM, 80MHz, 100-LQFP.
