You are not fitting a USB stack or a real-time OS in there. The 256 bytes of EEPROM are handy for calibration constants or configuration that survive a power cycle without wearing the Flash. ## 18 I/O and on-chip peripherals in a 20-pin TSSOP The 20-TSSOP package gives you 18 general-purpose I/O lines — enough for a handful of sensors, a small character LCD, or a few pushbuttons and LEDs. On-chip peripherals include a 10-channel 12-bit ADC, PWM timers, brown-out detect, power-on reset, DMA, and a watchdog. Communication is covered by I²C, SPI, and UART, plus IrDA if you need infrared.","metaTitle":"ST STM8L151F2P6 8-bit MCU, 16 MHz, 4 KB Flash, 20-TSSOP","metaDescription":"STM8L151F2P6 8-bit STM8 core MCU from STMicroelectronics, 16 MHz, 4 KB Flash, 1 KB RAM, 256 B EEPROM, 18 I/O, -40 to 85°C, 1.8-3.6V.

The STM8L EnergyLite series is designed for low-power operation, with stop-mode current in the microamp range. The 4 KB Flash and 1 KB RAM limit the firmware complexity, but for a simple sensor node or remote monitor it is a solid fit."},{"question":"What is the difference between STM8L151F2P6 and STM8L152F2P6?","answer":"The STM8L152F2P6 adds an LCD segment driver peripheral that the STM8L151F2P6 lacks. Otherwise the two parts share the same 8-bit STM8 core, 16 MHz clock, 4 KB Flash, 1 KB RAM, 256 B EEPROM, 18 I/O, and 20-TSSOP package. If your design does not need direct LCD drive, the STM8L151F2P6 covers the same ground at a lower BOM cost."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM8L151F2P6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM8L151F2P6 when reusing this data.
