The 6 KB EEPROM is a genuine hardware block, not emulated Flash, so you get 100 kcycle endurance per byte without wear-leveling code. ## Package and mounting The 100-LQFP (14x14 mm) is a hand-solderable QFP with 0.5 mm pitch — no BGA rework station needed, but a decent hot-air station and a fine-tip iron are the right tools.","metaTitle":"STM32L073VZT6D ARM Cortex-M0+ MCU, 32 MHz, 192 KB Flash","metaDescription":"STM32L073VZT6D 32-bit ARM Cortex-M0+ MCU from STMicroelectronics, 32 MHz, 192 KB Flash, 20 KB RAM, 6 KB EEPROM, 84 I/O, 100-LQFP, -40°C 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":"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)":"1.65V ~ 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":"Where can I buy STM32L073VZT6D and what is the price?","answer":"The STM32L073VZT6D is available to order through independent distribution."},{"question":"What is the replacement for STM32L073VZT6D if it becomes unavailable?","answer":"There is no direct pin-compatible second source from another manufacturer.
