Product details

The 19-channel 12-bit SAR ADC and four 12-bit DACs are the analog backbone for multi-phase current sensing and setpoint generation in digital power supplies and servo drives. Combined with the CANbus, USB, and QSPI interfaces, this part fits into fieldbus-connected actuator nodes or sensor hubs that need local signal conditioning. The 48-UFQFN package with exposed pad (7x7 mm) keeps the board area small, but the thermal pad needs a proper via stitch to the ground plane to get the junction temperature under control above 85°C ambient.

The 125°C ceiling means the processor can sit next to a power stage without a heatsink as long as the total dissipation stays within the package limits.

Frequently asked questions

What is the difference between STM32G491CCU3TR and STM32G491CCU6?

The difference is the shipping medium: the 'TR' suffix indicates Tape & Reel packaging, while the 'U6' variant typically ships in tray or tube. The silicon and functional ratings are identical.
