This wide range simplifies power architecture for portable and energy-harvesting designs. ## Memory configuration and firmware strategy With 128 KB of Flash, 20 KB of SRAM, and 6 KB of EEPROM, this MCU targets applications that need moderate code space plus non-volatile parameter storage without external memory. The 6 KB EEPROM is rated for 100k erase/write cycles per byte — sufficient for calibration data, configuration settings, and event logging over a decade-long product life. The 20 KB SRAM supports moderate data buffers, USB packet handling, and LCD frame buffers. ## Connectivity and analog integration USB 2.0 full-speed device support (with on-chip PHY) enables direct PC or charger connection without an external USB interface chip. The 16-channel 12-bit ADC samples at up to 1.14 Msps, adequate for multi-sensor acquisition in industrial control. Two 12-bit DAC channels generate analog setpoints or audio waveforms. The integrated LCD driver supports up to 8x40 or 4x44 segments, driving small alphanumeric displays directly. ## Lifecycle status and sourcing posture No direct pin-compatible second source is recorded, but the STM32L073 family shares the same footprint and peripheral set across density options, providing a roadmap for firmware-compatible upgrades within the family.","metaTitle":"ST STM32L073VBT7TR ARM Cortex-M0+ MCU, 32 MHz, 128 KB Flash","metaDescription":"STMicroelectronics STM32L073VBT7TR 32-bit MCU, 32 MHz, 128 KB Flash, 20 KB RAM, 6 KB EEPROM, USB, industrial temp -40 to 105°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":"Tape & Reel (TR)","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":"128KB (128K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 105°C (TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.6292","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/106d684d3945a6b1be3c8ecd66f3e28c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does STM32L073VBT7TR have USB support?","answer":"Yes, the STM32L073VBT7TR includes USB 2.0 full-speed device connectivity with an on-chip PHY, listed under its connectivity peripherals."},{"question":"What is a direct replacement for STM32L073VBT7TR?","answer":"No pin-compatible direct second-source replacement from another manufacturer is recorded.
