Housed in a 64-LQFP package with a 10x10 mm body and 0.50 mm pitch, the STM32L100R8T6A requires a four-layer PCB for reliable fan-out of the inner rows. At 32 MHz the core draws roughly 10 mA in active mode; the brown-out detect and POR blocks add negligible overhead, so a 200 mAh coin cell can power a sensor node for several months if the duty cycle is low. It is ROHS3 compliant, meeting the latest EU restriction on hazardous substances.","metaTitle":"STM32L100R8T6A MCU, ARM Cortex-M3, 32MHz, 64KB Flash","metaDescription":"STM32L100R8T6A ARM Cortex-M3 MCU, 32MHz, 64KB Flash, 8K x 8 RAM, -40 to 85°C.
