The 10-channel 12-bit ADC provides enough analog front-end resolution for current sensing or battery voltage monitoring without an external converter. ## Package and thermal — the 32-UFQFN exposed pad The 32-UFQFN Exposed Pad package with the supplier device package 32-UFQFPN (5x5 mm) is a space-saver for compact PCBs. ## Lifecycle — active, no last-time-buy pressure ST continues manufacturing this SKU, so there is no LTB window to manage and no forced redesign for a replacement. For new designs the STM32F0 family remains a supported portfolio; the base product number STM32F038 is the reference for ordering variants with different temperature grades or packaging options.","metaTitle":"STM32F038K6U6 STM32 ARM Cortex-M0 MCU, 48 MHz, 32 KB Flash","metaDescription":"STMicroelectronics STM32F038K6U6 32-bit ARM Cortex-M0 MCU at 48 MHz with 32 KB Flash, 4 KB RAM, 26 I/O, -40 to 85°C.

All share the same ARM Cortex-M0 core and supply range, so a board respin is not required to switch between them."},{"question":"Is STM32F038K6U6 recommended for new designs?","answer":"Yes. The Active lifecycle status and continued STM32F0 family support mean there is no near-term risk of obsolescence. The 48 MHz Cortex-M0 core, 32 KB Flash, and wide supply range make it a fit for low-power sensor nodes, motor-control feedback, and LIN-bus slave modules that are still in the concept or prototype phase."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F038K6U6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F038K6U6 when reusing this data.
