The 64-LQFP package (10x10 mm) gives access to 51 I/O, plus integrated peripherals including a 12-bit ADC (16 channels), a 12-bit DAC (2 channels), an LCD segment driver, and USB, I²C, SPI, and UART connectivity. ## Memory and peripheral fit for firmware OTA and data logging The 192 KB Flash (192K x 8) is the primary code store; the 20 KB SRAM (20K x 8) supports moderate-sized buffers and a real-time OS. The 6 KB EEPROM (6K x 8) is a genuine on-chip EEPROM, not emulated Flash — no wear-leveling needed for frequent parameter writes. The integrated LCD driver (up to 8x40 segments) reduces BOM for metering and control panels. ## Active lifecycle — no EOL risk for new designs For production buyers, this means no imminent obsolescence risk for ongoing builds. ## Package and supply rails — layout notes The 64-LQFP (10x10 mm) is a common footprint with 0.5 mm pitch, suitable for two-layer PCBs with careful routing. The device includes brown-out detect and POR, so external reset supervision is optional. Surface-mount assembly with MSL 3 handling is typical — bake before reflow if the moisture barrier bag has been open past the floor-life window.","metaTitle":"STM32L073RZT6 STMicroelectronics ARM Cortex-M0+ MCU, 32 MHz","metaDescription":"STM32L073RZT6 is a 32-bit ARM Cortex-M0+ MCU from STMicroelectronics with 192 KB Flash, 20 KB RAM, 6 KB EEPROM, 32 MHz clock, 64-LQFP, -40 to 85 °C.","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":"51","Core Processor":"ARM® Cortex®-M0+","Package / Case":"64-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":"64-LQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.2300","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/106d684d3945a6b1be3c8ecd66f3e28c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between STM32L073RZT6 and STM32L073RZT6TR?","answer":"The STM32L073RZT6 ships in a tray; the STM32L073RZT6TR variant ships in tape-and-reel packaging.
