The USB interface supports HID or CDC class for direct PC connection in data-logging applications. With 37 GPIOs in the 48-LQFP package, there is enough headroom for a parallel LCD interface alongside I²C and SPI peripherals. The internal oscillator saves two external capacitors and a crystal, reducing BOM count for cost-sensitive designs. ## Industrial temperature range and active lifecycle The brown-out detect and POR circuits ensure clean reset on supply dips. STMicroelectronics lists the STM32L072CZT6TR as Active. The base part number STM32L072 covers multiple memory and package variants for BOM flexibility.","metaTitle":"STM32L072CZT6TR STM32L0 MCU, 32MHz, 192KB Flash, 48-LQFP","metaDescription":"STM32L072CZT6TR ARM Cortex-M0+ MCU, 32MHz, 192KB Flash, 20KB RAM, 6KB EEPROM, USB, 10x12b ADC, -40 to 85°C, 48-LQFP.
