The pad also serves as the main electrical ground connection, so the solder paste coverage on that central pad matters for both thermal and electrical integrity. For a production BOM this removes the single-source obsolescence worry that haunts older 8-bit MCU lines.","metaTitle":"STM8L151C6U3 STMicroelectronics 8-bit MCU, 16 MHz","metaDescription":"STM8L151C6U3 8-bit MCU from STMicroelectronics STM8L EnergyLite series. 16 MHz core, 32 KB Flash, 2 KB RAM, 1 KB EEPROM, -40°C to 125°C.

The STM8L151C6U3 comes in a 48-UFQFN exposed-pad package (7x7 mm), while the STM8L151C6T6 uses a 48-LQFP package. The UFQFN saves board area and has a lower profile, but the LQFP is easier to hand-solder and inspect. Both share the same core, memory, and peripheral set."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM8L151C6U3","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM8L151C6U3 when reusing this data.
