It packs 192 KB of Flash program memory, 20 KB of SRAM, and a separate 6 KB EEPROM block, which saves an external EEPROM in many designs. ## Memory headroom and firmware strategy The 20 KB SRAM is tight for heavy data logging — budget for external SPI SRAM or use the 6 KB EEPROM for configuration parameters that survive resets. The EEPROM endurance is rated for 100k cycles per byte, so wear-leveling in firmware is advisable for frequently updated fields. It is ROHS3 compliant.","metaTitle":"STM32L073VZI6 32-bit ARM Cortex-M0+ MCU, 192KB Flash, 32 MHz","metaDescription":"STMicroelectronics STM32L073VZI6 32-bit ARM Cortex-M0+ MCU, 32 MHz, 192KB Flash, 20KB RAM, 6KB EEPROM, 84 I/O, 100-UFBGA, -40 to 85°C.","metaKeywords":null},"attributes":{"series":"STM32L0","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","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-UFBGA","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-UFBGA (7x7)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.2900","priceTiers":[{"qty":1,"price":"$6.29000","currency":"USD"},{"qty":10,"price":"$5.68400","currency":"USD"},{"qty":25,"price":"$5.41960","currency":"USD"},{"qty":80,"price":"$4.70575","currency":"USD"},{"qty":230,"price":"$4.49426","currency":"USD"},{"qty":440,"price":"$4.09770","currency":"USD"},{"qty":945,"price":"$3.56896","currency":"USD"},{"qty":2496,"price":"$3.43678","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/106d684d3945a6b1be3c8ecd66f3e28c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32L073VZI6/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32L073VZI6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32L073VZI6 when reusing this data.
