The base product number STM32L052 covers a density-and-package family, and the K8U3 variant (64 KB Flash, 32-pin UFQFPN) is a standard catalog item with consistent supply through ST's distribution network.","metaTitle":"STM32L052K8U3 ARM Cortex-M0+ MCU, 32 MHz, 64 KB Flash","metaDescription":"STMicroelectronics STM32L052K8U3 32-bit ARM Cortex-M0+ MCU at 32 MHz with 64 KB Flash, 8 KB SRAM, 2 KB EEPROM, -40°C to 125°C, 1.65-3.6 V.

They are not pin-compatible across package types. For a drop-in replacement, stay within the UFQFPN-32 footprint variants of the STM32L052 family; the Flash and SRAM sizes must match the application's memory map."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32L052K8U3","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32L052K8U3 when reusing this data.
