If your firmware needs more than 8 KB of runtime RAM for buffering or a large stack, you will bump into the ceiling; the STM32L0 series does have higher-RAM siblings, but they come in larger packages. If you are dual-sourcing, the STM32L0 series has several pin-compatible density variants — the STM32L053K8T6, for instance, shares the same 32-LQFP footprint and peripheral set, differing mainly in the USB and touch-sensing blocks. ## Package and footprint — 32-LQFP, no hidden surprises Housed in a 32-LQFP (7x7 mm) package with 27 general-purpose I/Os. The LQFP is a hand-solderable, inspection-friendly package — no hidden balls, no X-ray needed. For a field-service swap or a rework station, this is a part you can replace with a hot-air pencil and a pair of tweezers. The mounting is surface-mount, so it sits flat on the board with a standard 0.8 mm pitch. ## Connectivity and peripherals — what is on the bus On the control side, you get PWM timers, a watchdog timer, brown-out detect and POR, plus DMA for moving data without loading the core.","metaTitle":"STM32L052K8T6 ARM Cortex-M0+ MCU, 32 MHz, 64 KB Flash","metaDescription":"STMicroelectronics STM32L052K8T6 32-bit MCU with ARM Cortex-M0+ core, 32 MHz speed, 64 KB Flash, 8 KB RAM, 2 KB EEPROM, 1.65V-3.6V supply, -40°C to 85°C.","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":"Tray","RAM Size":"8K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"2K x 8","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"I²C, IrDA, SPI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"27","Core Processor":"ARM® Cortex®-M0+","Package / Case":"32-LQFP","Product Status":"Active","Data Converters":"A/D 10x12b; D/A 1x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32L052","Program Memory Size":"64KB (64K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"32-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.5600","priceTiers":[{"qty":1,"price":"$5.56000","currency":"USD"},{"qty":10,"price":"$4.99100","currency":"USD"},{"qty":25,"price":"$4.71840","currency":"USD"},{"qty":80,"price":"$4.08925","currency":"USD"},{"qty":250,"price":"$3.87952","currency":"USD"},{"qty":500,"price":"$3.48108","currency":"USD"},{"qty":1000,"price":"$2.93586","currency":"USD"},{"qty":2500,"price":"$2.85960","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/0e08a9b8947f5c1faa7dae988a3ee99f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32L052K8T6/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between STM32L052K8T6 and STM32L053K8T6?","answer":"Both share the same 32-LQFP footprint, 64 KB Flash, 8 KB RAM, and 2 KB EEPROM. The STM32L053K8T6 adds a touch-sensing controller (TSC) and a full-speed USB with crystal-less operation, while the L052 has USB but without the crystal-less feature and no TSC. If you do not need capacitive touch or crystal-less USB, the L052 is the cost-optimized pick."},{"question":"What is the equivalent of STM32L052K8T6?","answer":"Within the STM32L0 series, the STM32L053K8T6 is the closest pin-compatible sibling — same package, same memory map, same supply range. The STM32L151CBU6A from the STM32L1 series is a functional alternative with a Cortex-M3 core and more analog channels, but it is not pin-compatible and draws higher active current."},{"question":"How to program STM32L052K8T6?","answer":"It uses the standard ARM Serial Wire Debug (SWD) interface — a four-wire connection (SWDIO, SWCLK, VDD, GND) is all you need. ST's ST-LINK programmer or any CMSIS-DAP probe works. The bootloader in system memory also supports UART and USB DFU for field updates if the boot pins are strapped correctly."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32L052K8T6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32L052K8T6 when reusing this data.
