The 48 MHz core delivers about 44 DMIPS, which is sufficient for sensor fusion, CANopen node processing, or a USB CDC/ACM virtual COM port without choking. The 128 KB Flash can hold a FreeRTOS kernel, a USB stack, and a CANopen stack with room left for application code. The 16 KB SRAM handles a couple of moderate-sized buffers — enough for a 1 KB USB endpoint pair plus a CAN message queue. If your application needs more RAM for frame buffering or a larger heap, you'll want to step up to the STM32F072 with 32 KB SRAM (STM32F072VB), but for most control and gateway tasks this part keeps the BOM lean. ## USB + CAN on a single 48-pin QFN — board-space saver Having both USB 2.0 full-speed device and CAN 2.0B on the same 48-pin package eliminates a second MCU or an external USB-to-CAN bridge in dual-interface designs. The 37 GPIOs leave enough pins for a few sensors, an SPI flash, and an I²C display while still routing the USB DP/DM and CAN TX/RX pairs. The pad also serves as a low-inductance ground return for the USB transceiver, which helps with signal integrity on the DP/DM lines. ST lists the STM32F072CBU7 as Active. That means no last-time-buy notice is in effect, and the part continues to be manufactured and supported through ST's distribution channel.","metaTitle":"STM32F072CBU7 ARM Cortex-M0 MCU, 48 MHz, 128 KB Flash","metaDescription":"STMicroelectronics STM32F072CBU7 32-bit MCU with 48 MHz ARM Cortex-M0 core, 128 KB Flash, 16 KB SRAM, USB & CAN, -40°C to 105°C, 48-UFQFPN.

This makes it a strong candidate for a USB-to-CAN gateway or a dual-interface control node on a single chip."},{"question":"What is the difference between STM32F072CBU7 and STM32F072CBT6?","answer":"The two parts share the same core, Flash, SRAM, and peripheral set. The difference is the package: the CBU7 is a 48-UFQFPN (7x7 mm) with an exposed pad, while the CBT6 is a 48-LQFP (7x7 mm) without an exposed pad. The UFQFPN gives better thermal performance if you need to dissipate more than about 400 mW, but the LQFP is easier to hand-solder and inspect. Both are active and pin-compatible on the same 48-pin footprint, so a board could be laid out for either."},{"question":"What is the maximum operating frequency of STM32F072CBU7?","answer":"The core runs at 48 MHz maximum. At that speed the Flash requires one wait state for zero-wait access; the STM32F0's prefetch buffer helps keep single-cycle execution for most instructions. For timing-critical loops, consider placing code in SRAM or using the ART Accelerator."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F072CBU7","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F072CBU7 when reusing this data.
