It is not a number-cruncher — you are not running FFTs at audio rate — but it handles UART/I²C/SPI traffic, PWM generation, and the occasional ADC conversion without breaking a sweat. The 192 KB Flash and 20 KB RAM leave room for a modest FreeRTOS heap plus a few hundred lines of application code. The 6 KB EEPROM is a real convenience: no external serial EEPROM for calibration constants or boot flags, which saves a footprint and a line item on the BOM. That means it can sit in an engine bay, a rooftop solar inverter, or a cold-chain logger without derating. ## Package and pin count — rework bench friendly 48-LQFP with a 7x7 mm body and 0.5 mm pitch. That is a hand-solderable package — no hot-air station required, no BGA rework. On a field-service call, you can swap this with a fine-tip iron and a loupe. The 40 I/O give you enough for a keypad, a small character LCD, and a few sensor interrupts. Surface-mount, so it sits on the top side of a two-layer board without vias under the part.","metaTitle":"STM32L071CZT3 ARM Cortex-M0+ MCU, 32 MHz, 192 KB Flash","metaDescription":"STMicroelectronics STM32L071CZT3 32-bit MCU with 32 MHz ARM Cortex-M0+, 192 KB Flash, 20 KB RAM, 6 KB EEPROM, -40 to 125°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, POR, PWM, WDT","Connectivity":"I²C, IrDA, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"40","Core Processor":"ARM® Cortex®-M0+","Package / Case":"48-LQFP","Product Status":"Active","Data Converters":"A/D 13x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32L071","Program Memory Size":"192KB (192K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"48-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.2426","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/800dd075f25aea742da71c4c42c978e5.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is STM32L071CZT3 obsolete or active?","answer":"Active.
