That is enough for a USB HID or a CANopen slave node running a few hundred lines of control code. ## EOL lifecycle — plan the replacement now The STM32F042C4T6 carries an end-of-life (hot) status. The manufacturer has discontinued the part; last-time-buy windows may have closed or are closing.","metaTitle":"ST STM32F042C4T6 ARM Cortex-M0 MCU, 48 MHz, 16 KB Flash","metaDescription":"STMicroelectronics STM32F042C4T6 32-bit MCU, 48 MHz Cortex-M0, 16 KB Flash, 6 KB RAM, USB/CAN, -40 to 85°C, 48-LQFP.

The STM32F072C8T6 also fits the same footprint and adds a larger memory array (64 KB Flash, 16 KB RAM) while keeping the Cortex-M0 core."},{"question":"Where can I buy STM32F042C4T6?","answer":"We source STM32F042C4T6 through our independent supply chain and quote it to order against an RFQ. Availability and current pricing are confirmed at quote time — submit an RFQ through the storefront for a firm response with date-code and packaging condition."},{"question":"What is STM32F042C4T6's listed speed?","answer":"The core runs at 48 MHz, which is the maximum clock for the STM32F0 Cortex-M0 line. That is enough for USB full-speed (12 Mbps) and CAN 2.0B at 1 Mbps without stalling the CPU on interrupt handling."},{"question":"What compliance documentation is available for STM32F042C4T6?","answer":"RoHS and REACH compliance declarations, along with conflict minerals reports, are available on request for each shipment lot. The part is not AEC-Q100 qualified; it is rated for industrial temperature (-40 to 85 °C)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F042C4T6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F042C4T6 when reusing this data.
