Product details

170 MHz Cortex-M4F with a full analog toolbox

The part is in a 64-LQFP package with 52 I/O lines, making it a practical fit for motor drives, digital power supplies, and industrial sensors where board space is tight but you still need access to multiple PWM and ADC channels.

Analog peripherals that save external components

What sets this MCU apart from a plain Cortex-M4 part is the analog front-end: 26 channels of 12-bit ADC and 7 channels of 12-bit DAC. That many ADC channels can handle three-phase current sensing plus a couple of voltage and temperature feedback lines without an external multiplexer. The seven DACs are useful for generating analog setpoints or reference voltages in multi-loop control.

Active lifecycle — no near-term LTB concern

The base product number is STM32G474, and the series is the STM32G4 family, which remains a mainstream offering.

Frequently asked questions

What is the maximum clock speed of STM32G474RBT6?

The core runs at 170 MHz. That is the maximum clock speed for this ARM Cortex-M4F part, which includes a single-precision FPU for math-heavy control loops.

What are the alternatives to STM32G474RBT6?

A lower-speed alternative in the STM32 portfolio is the STM32L151CBU6A, which runs a Cortex-M3 core at 32 MHz with less RAM and fewer analog channels. The STM32G474 is the higher-performance choice for applications needing the 170 MHz clock, the FPU, and the 26-channel ADC bank.
