Product details

48 MHz Cortex-M0 in a 1.8 V-only QFN

The STM32F048C6U6TR: The 48-UFQFN exposed pad package (7x7 mm) keeps board area small and thermal transfer direct to the PCB ground plane.

Supply voltage — the 1.8 V-only constraint

The 1.65 V to 1.95 V supply is the single most important BOM constraint. It is not a 3.3 V part and cannot tolerate 2.5 V or 3.0 V on VDD. The upside is very low dynamic power at 48 MHz and compatibility with 1.8 V logic families without level shifters on the I/O.

The base product number is STM32F048, so any future PCN or die revision will carry that root.

Frequently asked questions

What is the closest pin-compatible alternative to STM32F048C6U6TR?

Within the STM32F0 series, the STM32F042 family shares the same 48-UFQFPN footprint and 1.8 V supply range, but memory and peripheral options differ. The STM32F048C6U6TR is distinguished by its 32 KB Flash and HDMI-CEC peripheral. For a direct drop-in, verify the specific memory and feature set against your firmware requirements.

Where can I find the STM32F048C6U6TR datasheet?

The full datasheet and reference manual are published by STMicroelectronics under the base product number STM32F048. It covers the 48 MHz Cortex-M0 core, memory map, peripheral registers, and electrical characteristics including the 1.65 V to 1.95 V supply range.
