The 6 KB EEPROM is the standout — it stores calibration constants, device configuration, and event logs without needing an external I²C EEPROM, saving board space and BOM cost. The EEPROM endurance is typically 100k cycles per byte, which suits frequent parameter updates in metering or field-configurable devices. ## Package and footprint: 48-LQFP Housed in a 48-LQFP package (7x7 mm body), the STM32L071CZT7 offers 37 general-purpose I/Os. The LQFP footprint is hand-solderable and inspectable, which benefits prototyping and low-volume production. The 0.5 mm pitch requires careful PCB routing for the supply and ground pins, but the package is standard across the STM32L0 series, easing layout reuse if you migrate between density options.","metaTitle":"ST STM32L071CZT7 ARM Cortex-M0+ MCU, 32 MHz, 192 KB Flash","metaDescription":"STMicroelectronics STM32L071CZT7 32-bit MCU, ARM Cortex-M0+ at 32 MHz, 192 KB Flash, 20 KB SRAM, 6 KB EEPROM, -40 to 105°C, 48-LQFP.
