The 4 KB RAM (4K x 8) supports moderate data buffers for protocol stacks or sensor fusion. For designs that need field-updatable firmware, the Flash block size and write endurance should be checked against the OTA strategy — the datasheet's programming section covers the specifics. On-chip peripherals include brown-out detect, power-on reset, a watchdog timer, DMA, and an internal oscillator — reducing external BOM count. ## Package and I/O — 64-LQFP with 54 GPIO The LQFP footprint is standard for mid-density MCUs and reflows well with typical lead-free profiles.","metaTitle":"STMicroelectronics STM8L151R8T3 8-bit MCU, 16 MHz","metaDescription":"ST STM8L151R8T3 8-bit MCU from EnergyLite series: 16 MHz core, 64 KB Flash, 4 KB RAM, 2 KB EEPROM, 54 I/O, -40 to 125°C.

If your application requires the extended temperature range, the T3 is the correct choice; otherwise, the T6 may be a cost-effective alternative. Pin compatibility should be verified against the respective datasheets."},{"question":"What programmer is compatible with STM8L151R8T3?","answer":"The STM8L151R8T3 uses the standard STM8 SWIM (Single Wire Interface Module) debug interface. Compatible programmers include the ST-LINK/V2, ST-LINK/V3, and third-party tools that support SWIM. The SWIM pin is typically on the reset line, so the programmer connects via a 4-pin header (SWIM, GND, VDD, and optionally NRST)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM8L151R8T3","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM8L151R8T3 when reusing this data.
