It determines the instruction execution rate for polling loops, interrupt latency, and peripheral data handling. With 16 KB of Flash, the firmware budget is tight for complex protocol stacks but adequate for dedicated sensor fusion, motor commutation, or UART-to-I²C bridge code. The 2 KB RAM and 1 KB EEPROM together define the volatile and non-volatile data storage — the EEPROM is useful for calibration constants or configuration parameters that survive power cycles without external serial memory. ## Analog integration and I/O count The 41 general-purpose I/O lines provide enough headroom for a keypad matrix, segment LCD drive, or parallel sensor interface.","metaTitle":"STM8L151C4T6TR STM8 8-bit MCU, 16 MHz, 16 KB Flash, 48-LQFP","metaDescription":"STMicroelectronics STM8L151C4T6TR 8-bit MCU from STM8L EnergyLite series. 16 MHz core, 16 KB Flash, 2 KB RAM, 1 KB EEPROM, 41 I/O, 25x12b ADC, 1x12b DAC.","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":"Tape & Reel (TR)","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~85°C(TA)","Supplier Device Package":"48-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5347","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a6a751855e41d176288c66669f17dd61.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8L151C4T6TR/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM8L151C4T6TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM8L151C4T6TR when reusing this data.
