The 16-channel 10-bit ADC covers analog inputs like thermocouple or current-sense signals, and the I²S interface handles digital audio if the application needs it. ## Industrial temperature grade — deployment environment The 1.235 V to 1.365 V core supply is tight — the board's regulator tolerance needs to stay inside that window, especially at the temperature extremes where the LDO reference drifts. The Stellaris line was acquired and absorbed into the TI MCU portfolio; the closest functional match today would be a Tiva-C series part with similar peripheral mix and pin count, but those are not pin-to-pin compatible — the board layout would need a re-spin. ## Package and mounting — 100-LQFP Supplied in a 100-LQFP (14x14 mm) surface-mount package.","metaTitle":"LM3S2U93-IQC80-A2 Stellaris ARM Cortex-M3 MCU, 80MHz","metaDescription":"LM3S2U93-IQC80-A2 Stellaris ARM Cortex-M3 MCU: 80MHz core, 384KB Flash, 96KB SRAM, 67 I/O, industrial temp -40°C to 85°C.
