The 6 KB EEPROM is the standout feature — it stores calibration constants, configuration profiles, and security keys without wearing the Flash, and it survives 100k write cycles typical of the STM32L0 family. That saves a 1-cent external EEPROM and one I²C bus slot on the BOM. The supplier device package is 64-LQFP (10x10), so the footprint matches the common 64-pin LQFP land pattern. The STM32L0 series is a mature, broadly deployed family, so independent-channel availability is reliable.","metaTitle":"STM32L073RZT6TR MCU, ARM Cortex-M0+, 32MHz, 192KB Flash","metaDescription":"STMicroelectronics STM32L073RZT6TR 32-bit MCU, ARM Cortex-M0+, 32 MHz, 192 KB Flash, 20 KB SRAM, 6 KB EEPROM, 1.8–3.6 V, -40 to 85°C, 64-LQFP.","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":"Tape & Reel (TR) Cut Tape (CT)","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 15x12b; 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":"$6.5200","priceTiers":[{"qty":1,"price":"$6.52000","currency":"USD"},{"qty":10,"price":"$5.85500","currency":"USD"},{"qty":25,"price":"$5.53480","currency":"USD"},{"qty":100,"price":"$4.79690","currency":"USD"},{"qty":250,"price":"$4.55092","currency":"USD"},{"qty":500,"price":"$4.08352","currency":"USD"},{"qty":1000,"price":"$3.44394","currency":"USD"},{"qty":2000,"price":"$3.27174","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/106d684d3945a6b1be3c8ecd66f3e28c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32L073RZT6TR/alternatives.json"},"ai":{"faq":[{"question":"What is the flash size of STM32L073RZT6TR?","answer":"The program memory is 192 KB of Flash, organised as 192K x 8 bits."},{"question":"What package does STM32L073RZT6TR use?","answer":"It comes in a 64-LQFP (10x10 mm) surface-mount package with a 0.5 mm pitch."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32L073RZT6TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32L073RZT6TR when reusing this data.
