The 16 KB RAM (organised as 16K x 8) handles a few dozen frames of sensor data or a small protocol buffer. ## 48-UFQFPN (7x7 mm) — compact, thermally enhanced, hand-solderable The 48-UFQFN exposed-pad package (7x7 mm body) is a space-saver for two-layer boards where every square millimetre counts. ## Industrial temperature range and integrated peripherals The internal oscillator trims to 1% accuracy over temperature, so many designs can skip the external crystal for the main clock — though the RTC still needs a 32.768 kHz crystal if timekeeping matters. The STM32F1 series has broad installed base and multiple second-source options within the family, so supply risk is manageable even in constrained markets.","metaTitle":"STM32F101CBU6TR STM32F1 ARM Cortex-M3 MCU, 36 MHz","metaDescription":"STMicroelectronics STM32F101CBU6TR 32-bit MCU: ARM Cortex-M3 at 36 MHz, 128 KB Flash, 16 KB RAM, 37 I/O, -40°C to 85°C, 48-UFQFPN.

The key difference is the core clock: the F101 runs at 36 MHz, while the F103 runs at 72 MHz. The F103 also adds USB and a second ADC. If your firmware does not depend on the higher clock or USB, the F101 is a drop-in replacement at a lower BOM cost."},{"question":"Does STM32F101CBU6TR support USB?","answer":"No. The STM32F101 Access Line does not include a USB peripheral. If your design requires USB connectivity, look at the STM32F103 series (which adds USB device) or the STM32F105/107 series (USB OTG)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F101CBU6TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F101CBU6TR when reusing this data.
