ST lists the STM8L151C4T3 as active product status. ## Package and mounting — 48-LQFP with 7x7 mm body The 48-LQFP (7x7 mm) is a fine-pitch surface-mount package with 0.5 mm lead pitch. The 41 I/O count is high for the package size, so fan-out routing on a two-layer board needs careful trace spacing.","metaTitle":"STM8L151C4T3 8-bit MCU, 16 MHz, 16 KB Flash, -40°C to 125°C","metaDescription":"STMicroelectronics STM8L151C4T3 8-bit MCU, 16 MHz core, 16 KB Flash, 2 KB RAM, 1 KB EEPROM, -40°C to 125°C, 48-LQFP.","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":"STM8L EnergyLite","Package":"Tray","RAM Size":"2K x 8","Core Size":"8-Bit","EEPROM Size":"1K x 8","Peripherals":"Brown-out Detect/Reset, DMA, IR, POR, PWM, WDT","Connectivity":"I²C, IrDA, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"41","Core Processor":"STM8","Package / Case":"48-LQFP","Product Status":"Active","Data Converters":"A/D 25x12b; D/A 1x12b","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 ~ 125°C (TA)","Supplier Device Package":"48-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.7458","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a6a751855e41d176288c66669f17dd61.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8L151C4T3/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to STM8L151C4T3?","answer":"The STM8L151C6 (with 32 KB Flash) is pin-compatible in the same 48-LQFP footprint and shares the same peripheral set. The main difference is program memory density — 16 KB vs 32 KB — so firmware that fits in the smaller Flash can move up without a board spin."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM8L151C4T3","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM8L151C4T3 when reusing this data.
