The 16-channel 12-bit ADC covers multi-sensor analog front ends without an external mux. Brown-out detect and POR are integrated, reducing external supervisor IC count. ## Package and supply rails — layout notes The 100-LQFP (14x14 mm) is a standard fine-pitch package — 0.5 mm pitch — that routes easily on a 4-layer board with a ground plane. The core supply is a narrow 1.235 V to 1.365 V rail, which means a dedicated low-noise regulator is required; the I/O bank runs separately. An internal oscillator is available, though an external crystal improves accuracy for time-sensitive protocols.","metaTitle":"LM3S1G58-IQC80-A1T Stellaris ARM Cortex-M3 MCU, 80MHz","metaDescription":"LM3S1G58-IQC80-A1T Stellaris ARM Cortex-M3 MCU, 80MHz, 384KB Flash, 64K SRAM, 60 I/O, industrial temp.
