This saves board area, reduces BOM count, and simplifies firmware development — the MCU handles both application logic and touch sensing in a single chip. For designs requiring capacitive buttons, sliders, or proximity wake-up, this peripheral is the key differentiator versus a general-purpose 8-bit MCU without touch hardware. ## Package and footprint — 48-UFQFN with exposed pad The 23 I/O lines are sufficient for small touch panels or sensor aggregation. MSL level should be verified from the latest ST packaging data.","metaTitle":"ST STM8TL53C4U6 8-bit MCU, 16 MHz, 16 KB Flash, ProxSense","metaDescription":"STMicroelectronics STM8TL53C4U6 8-bit MCU with 16 MHz STM8 core, 16 KB Flash, 4K x 8 RAM, 2K x 8 EEPROM, ProxSense touch, I²C/SPI/UART, -40 to 85°C.","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":"23","Core Processor":"STM8","Package / Case":"48-UFQFN Exposed Pad","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":"48-UFQFPN (7x7)","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.6762","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/418346685aa8d3a54c4e6903e4b098db.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8TL53C4U6/alternatives.json"},"ai":{"faq":[{"question":"What is the core processor of STM8TL53C4U6?","answer":"The core processor is the STM8, an 8-bit architecture running at up to 16 MHz."},{"question":"How many I/O pins does STM8TL53C4U6 have?","answer":"The STM8TL53C4U6 provides 23 general-purpose I/O pins."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM8TL53C4U6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM8TL53C4U6 when reusing this data.
