With 16 I/Os, I²C, SPI, UART, and a 9-channel 12-bit ADC, it fits into compact 20-TSSOP designs where every millimetre of board space counts. ## Memory budget — what fits in 8 KB Flash and 2 KB SRAM 8 KB of Flash is tight: a typical STM32L0 HAL plus a minimal RTOS kernel leaves about 4 KB to 5 KB for application code. The 2 KB SRAM handles a few local buffers and a modest call stack. The 512 bytes of EEPROM are useful for calibration constants, node IDs, or fault logs that survive a power cycle — no external EEPROM needed. If your firmware image or data buffers exceed this, you are looking at the next density step in the STM32L0 family, like the STM32L031 with 32 KB Flash. ## Supply and temperature — where it works The 1.65 V minimum supply means this MCU keeps running as a single-cell Li-ion battery discharges to its cutoff. The 3.6 V maximum covers a 3.3 V rail with margin. ## Lifecycle and sourcing reality No last-time-buy or obsolescence risk for current designs.","metaTitle":"STM32L011F3P6 ARM Cortex-M0+ 32-bit MCU, 32 MHz, 8 KB Flash","metaDescription":"STM32L011F3P6 32-bit ARM Cortex-M0+ MCU from STMicroelectronics, 32 MHz, 8 KB Flash, 2 KB SRAM, 512 B EEPROM, -40°C to 85°C, 20-TSSOP.","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":"Tube","RAM Size":"2K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"512 x 8","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"I²C, IrDA, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"16","Core Processor":"ARM® Cortex®-M0+","Package / Case":"20-TSSOP (0.173\\\", 4.40mm Width)","Product Status":"Active","Data Converters":"A/D 9x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32L011","Program Memory Size":"8KB (8K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"20-TSSOP","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.6100","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9c099abe8e75939b63e0c0b04b4c1a1d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to the STM32L011F3P6?","answer":"Within the STM32L0 series, the STM32L011F3P6 shares the same 20-TSSOP footprint and pinout as other STM32L011 variants with different Flash densities (e.g., STM32L011D3P6 with 8 KB Flash).
