Product details

Peripheral set and I/O — what connects where

The STM32F058T8Y6TR: The 13-channel 12-bit ADC and single 12-bit DAC handle analog sensor conditioning and simple waveform generation.

WLCSP package — what it means for assembly and rework

The 36-ball WLCSP (0.4 mm pitch typical) demands a clean stencil and a reflow profile matched to the solder-ball alloy. No exposed paddle — thermal dissipation relies on the PCB copper plane under the package. The small ball diameter means visual inspection under a microscope; X-ray is recommended for hidden solder-joint voids. Hot-air rework is possible with a fine nozzle, but the risk of adjacent component displacement is higher than with a QFN.

For dual-sourcing resilience, the STM32F0 family includes pin-compatible density variants (e.g., 32 KB Flash / 6 KB RAM) that share the same WLCSP footprint, though the exact RAM and Flash sizes differ.

Frequently asked questions

What are the alternatives to STM32F058T8Y6TR?

Within the STM32F0 family, pin-compatible WLCSP variants with different Flash/RAM densities exist — for example, the STM32F058C8U6 (48-pin UFQFPN) shares the same core and peripheral set but uses a larger package. No exact pin-for-pin second source from another manufacturer is listed; for a drop-in replacement, stick to the same base product number (STM32F058) with the desired Flash and RAM size.
