The 6 KB EEPROM is a differentiator: it supports byte-level erase/write at up to 100k cycles, so you can store calibration constants, device IDs, or usage counters without wearing the Flash or adding a separate EEPROM chip. That saves board area and BOM cost. ## Peripheral set and connectivity The STM32L072KZU6TR includes a 10-channel 12-bit ADC and a dual 12-bit DAC for analog front-end tasks. The brown-out detect, POR, and watchdog peripherals are standard for reliable unattended operation. ## Package and thermal pad layout Housed in a 32-UFQFN with an exposed pad (5x5 mm body), this package is compact enough for space-constrained designs. The 25 available I/Os are enough for a sensor hub or a simple user interface with a few buttons and LEDs.","metaTitle":"ST STM32L072KZU6TR ARM Cortex-M0+ MCU, 32 MHz, 192 KB Flash","metaDescription":"STMicroelectronics STM32L072KZU6TR 32-bit ARM Cortex-M0+ MCU at 32 MHz with 192 KB Flash, 20 KB RAM, 6 KB EEPROM.
