The 6 KB of embedded EEPROM is a useful differentiator — it saves an external serial EEPROM for calibration constants or configuration data that must survive a firmware update. The 32 MHz Cortex-M0+ core handles moderate control loops and protocol stacks without breaking a sweat, though the flash wait state needs to be set to 1 when the system clock exceeds 16 MHz to avoid a hard fault on the first branch. The brown-out detect and POR circuits keep the core from running in an undefined state during power ramps.","metaTitle":"STM32L071CZT6TR ARM Cortex-M0+ MCU, 32 MHz, 192 KB Flash","metaDescription":"STMicroelectronics STM32L071CZT6TR 32-bit MCU with ARM Cortex-M0+ core, 32 MHz speed, 192 KB Flash, 20 KB RAM, 6 KB EEPROM, 48-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, POR, PWM, WDT","Connectivity":"I²C, IrDA, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"37","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 ~ 85°C (TA)","Supplier Device Package":"48-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.3400","priceTiers":[{"qty":1,"price":"$5.34000","currency":"USD"},{"qty":10,"price":"$4.79300","currency":"USD"},{"qty":25,"price":"$4.53160","currency":"USD"},{"qty":100,"price":"$3.92740","currency":"USD"},{"qty":250,"price":"$3.72596","currency":"USD"},{"qty":500,"price":"$3.34330","currency":"USD"},{"qty":1000,"price":"$2.81966","currency":"USD"},{"qty":2400,"price":"$2.67868","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/bdf0122ce3763ca70cc9e1606c816ad1.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32L071CZT6TR/alternatives.json"},"ai":{"faq":[{"question":"What is the flash memory size of the STM32L071CZT6TR?","answer":"The STM32L071CZT6TR has 192 KB of Flash program memory, organized as 192K x 8 bits."},{"question":"What programming tools support the STM32L071CZT6TR?","answer":"The STM32L071CZT6TR uses the standard ARM Cortex-M0+ SWD (Serial Wire Debug) interface.
