The 20-TSSOP package with 0.65 mm pitch and 4.4 mm body width is hand-solderable and reflow-friendly at MSL 3. For designs that see sustained junction temperatures above 85°C, step up to the STM32F0 extended-temperature variants or the STM32F051 family with a 105°C rating. ## Active lifecycle — no near-term obsolescence concern The STM32F0 series is a mature, volume-driven platform; PCNs are rare and usually limited to wafer-fab or assembly-site changes.","metaTitle":"ST STM32F031F4P6 ARM Cortex-M0 MCU, 48 MHz, 16 KB Flash","metaDescription":"STMicroelectronics STM32F031F4P6 32-bit MCU with ARM Cortex-M0 core at 48 MHz, 16 KB Flash, 4 KB SRAM, 15 I/O, -40 to 85°C.

At this speed, the Flash requires one wait state for zero-wait access, which the STM32F0 clock-configuration routine handles automatically via the internal PLL."},{"question":"Does STM32F031F4P6 have a DAC?","answer":"No, the STM32F031F4P6 does not include a DAC. It has a 12-channel, 12-bit ADC but no digital-to-analog converter. For a DAC, consider the STM32F051 series, which includes a 1-channel 12-bit DAC in a larger package."},{"question":"What are the alternatives or equivalents to STM32F031F4P6?","answer":"The closest functional alternative within the same 20-TSSOP package is the STM32F030F4P6 (same core, 48 MHz, 16 KB Flash, but without I²S and with a narrower peripheral set). For more I/Os and a DAC, the STM32F051K6T7 (32-LQFP, 48 MHz, 32 KB Flash, 25 I/O, -40 to 105°C) requires a board footprint change. Both are pin-compatible only within the same package variant — verify the datasheet pin assignment before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F031F4P6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F031F4P6 when reusing this data.
