It packs 192 KB of Flash program memory, 20 KB of SRAM, and a useful 6 KB of true EEPROM — that last bit is rare in this class and saves an external serial EEPROM for calibration or configuration data. The 100-pin LQFP package brings out 84 I/Os, including support for a segment LCD controller and USB, making it a fit for metering, sensor hubs, and human-machine interface panels that need to run for years on a coin cell or two AA batteries. ## Memory and peripheral fit for field-upgradable designs The 6 KB EEPROM is a standout — it lets you store calibration constants, meter readings, or configuration profiles without wearing the Flash or adding a serial EEPROM footprint. On the peripheral side, the USB interface supports device and host modes, and the LCD controller drives up to 8x40 or 4x44 segment displays directly. The 12-bit ADC has 16 channels, and there are two 12-bit DACs for analog output. Brown-out detect and POR are integrated, so external supervisor ICs can often be skipped. ## Lifecycle status — active for new designs STMicroelectronics lists the STM32L073VZT6 as Active (current production). ROHS3 compliant. The 100-LQFP (14x14 mm body) is a hand-solderable package with 0.5 mm pitch — no hot-air station required for rework, just a fine-tip iron and flux. The exposed pad is not present on this package variant; all thermal dissipation goes through the leads.","metaTitle":"STM32L073VZT6 STMicroelectronics ARM Cortex-M0+ MCU, 32MHz","metaDescription":"STM32L073VZT6 32-bit ARM Cortex-M0+ MCU with 192KB Flash, 20K RAM, 6K EEPROM, USB, LCD, 100-LQFP.
