It packs 16 KB of Flash program memory, 4K x 8 of RAM, and 2K x 8 of EEPROM in a compact 28-UFQFPN package measuring 4x4 mm. At 16 MHz, this STM8 core delivers enough throughput for real-time capacitive sensing scans, PWM generation for LED dimming or motor speed control, and UART/I²C/SPI communication without a separate coprocessor. If your application needs faster math or higher update rates, the 16 MHz ceiling sets the boundary — but for typical touch-interface and control-loop tasks, it leaves comfortable headroom. ## Memory map: Flash, RAM, and EEPROM allocation With 16 KB of Flash, 4 KB of RAM, and 2 KB of EEPROM, the memory budget suits firmware that combines a capacitive-sensing library, communication stack, and application logic. The EEPROM is useful for storing calibration constants, configuration parameters, or last-state data without wearing the Flash. The 4 KB RAM limits buffering — heavy data logging or large frame buffers would push this part to its ceiling, but it is adequate for typical sensor polling and UI response. ## Peripherals and I/O in a 28-pin package The 28-UFQFPN exposes 17 I/O pins, which must share duty among POR, ProxSense touch channels, PWM outputs, WDT, and the I²C/SPI/UART serial interfaces. The ProxSense block is the key differentiator — it handles capacitive sensing in hardware, offloading the CPU. The UART/USART and I²C/SPI connectivity cover most sensor and display communication needs. The 17 I/O count means careful pin allocation is required if multiple peripherals run simultaneously, but for a touch-interface controller with a few serial peripherals, it is workable. For dual-sourcing resilience, the STM8L151 family shares the same STM8 core but lacks the ProxSense peripheral — verify pin-compatibility against your specific layout before substituting.","metaTitle":"ST STM8TL52G4U6 8-bit MCU, 16 MHz, 16 KB Flash, 28-UFQFPN","metaDescription":"STMicroelectronics STM8TL52G4U6 8-bit STM8 MCU, 16 MHz core, 16 KB Flash, 4K x 8 RAM, 2K x 8 EEPROM, ProxSense, I²C/SPI/UART, -40°C to 85°C, 28-UFQFPN.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"16MHz","Series":"STM8T","Package":"Tray","RAM Size":"4K x 8","Core Size":"8-Bit","EEPROM Size":"2K x 8","Peripherals":"POR, ProxSense, PWM, WDT","Connectivity":"I²C, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"17","Core Processor":"STM8","Package / Case":"28-UFQFN","Product Status":"Active","Data Converters":"-","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM8","Program Memory Size":"16KB (16K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"28-UFQFPN (4x4)","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.7500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/418346685aa8d3a54c4e6903e4b098db.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8TL52G4U6/alternatives.json"},"ai":{"faq":[{"question":"What are the peripherals of STM8TL52G4U6?","answer":"The integrated peripherals include POR (Power-On Reset), ProxSense capacitive touch sensing, PWM, and WDT."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM8TL52G4U6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM8TL52G4U6 when reusing this data.
