Product details

ARM Cortex-M4 at 72 MHz — the control-loop workhorse

The 21-channel 12-bit ADC and three 12-bit DAC channels are the standout analog features here — this part carries more ADC channels than many Cortex-M4 peers, which matters when you are sensing multiple phases or monitoring several analog feedback paths on the same die.

Supply range and package — layout-fit check

Operates from 2.0 V to 3.6 V on Vcc/Vdd, which covers a 3.3 V regulated rail with margin for a 3.0 V lithium cell on the low end.

For a production BOM this means you can plan multi-year builds without an obsolescence-driven redesign.

Frequently asked questions

What is the core architecture of STM32F334R8T6TR?

The core is a 32-bit ARM Cortex-M4 single-core processor, which includes a single-precision floating-point unit (FPU) and DSP instructions.

Is STM32F334R8T6TR compatible with STM32F334R8T6?

Yes — the base product number is STM32F334, and the die, package, and pinout are identical. The TR suffix only denotes tape-and-reel packaging instead of tray, so a board designed for STM32F334R8T6 will accept this variant.
