An on-chip 12-bit ADC with 16 channels and a dual 12-bit DAC cover most sensor and control-loop needs without external converters. ## Supply voltage and battery operation A single lithium cell (3.0 V – 4.2 V) or two series alkaline cells (1.8 V – 3.0 V) can power the MCU without a boost regulator, saving board space and quiescent losses. ## Memory and peripheral mix The 192 KB Flash is partitioned for firmware and bootloader staging; the 20 KB SRAM handles moderate data buffers, and the 6 KB true EEPROM eliminates the need for Flash-emulation wear-leveling in the application layer. The 84 GPIOs in the 100-LQFP package give headroom for a parallel LCD interface (the LCD peripheral is listed), a keypad matrix, and multiple chip selects without bit-banging.","metaTitle":"STMicroelectronics STM32L073VZT6U MCU, 32MHz Cortex-M0+","metaDescription":"STM32L073VZT6U 32-bit ARM Cortex-M0+ MCU, 32 MHz, 192 KB Flash, 20 KB RAM, 6 KB EEPROM, 1.8V-3.6V supply, -40°C to 85°C, 100-LQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"32MHz","Series":"STM32L0","Package":"Tray","RAM Size":"20K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"6K x 8","Peripherals":"Brown-out Detect/Reset, DMA, I²S, LCD, POR, PWM, WDT","Connectivity":"I²C, IrDA, LINbus, SPI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"84","Core Processor":"ARM® Cortex®-M0+","Package / Case":"100-LQFP","Product Status":"Active","Data Converters":"A/D 16x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32L073","Program Memory Size":"192KB (192K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.2900","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/106d684d3945a6b1be3c8ecd66f3e28c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is STM32L073VZT6U suitable for battery-operated devices?","answer":"Yes — the 1.8 V minimum supply lets it run from a nearly depleted battery, and the ultra-low-power STM32L0 architecture is designed for extended battery life in sensor nodes and portable instruments."},{"question":"How does STM32L073VZT6U compare to STM32L072?","answer":"The STM32L072 is a close sibling in the same STM32L0 family, but the STM32L073 adds a dedicated 6 KB EEPROM and an LCD driver peripheral — the L072 lacks both.
