With 40 general-purpose I/Os, a 13-channel 12-bit ADC, and connectivity including I2C, SPI, and UART/USART, it fits sensor fusion, motor feedback, and IoT edge-node designs where every microamp matters. ## 192 KB Flash plus 6 KB EEPROM — storage strategy The 192 KB Flash (192K x 8) provides ample space for application code and bootloader stages. The 6 KB EEPROM is a separate, non-volatile block that survives 100k erase/write cycles — useful for storing device serial numbers, calibration tables, or configuration parameters without wearing the Flash. The 20 KB SRAM handles stack, heap, and DMA buffers for moderate data acquisition or communication payloads. ## Peripheral set and I/O count Peripherals include brown-out detect, POR, PWM, WDT, DMA, and an I2S interface for audio or serial data streaming. The 13-channel 12-bit ADC covers analog inputs like temperature sensors, potentiometers, or current shunts. With 40 I/Os in the 48-LQFP package, you have enough pins to interface a small keypad, a character LCD, and a few external sensors without a port expander. ## Package and temperature grade for assembly planning Housed in a 48-LQFP (7x7 mm) surface-mount package, this MCU is straightforward for reflow assembly and visual inspection.","metaTitle":"STM32L071CZT3TR ARM Cortex-M0+ MCU, 32 MHz, 192 KB Flash","metaDescription":"STM32L071CZT3TR is an STM32L0 series 32-bit ARM Cortex-M0+ MCU with 192 KB Flash, 20 KB RAM, 6 KB EEPROM, operating at 32 MHz.","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":"Tape & Reel (TR)","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":"$3.0804","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/800dd075f25aea742da71c4c42c978e5.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between STM32L071CZT3TR and STM32L071CBT3?","answer":"Both are STM32L0-series MCUs with the same ARM Cortex-M0+ core, 32 MHz speed, and 48-LQFP package.
