Product details

It carries 128K x 8 of SRAM and a dense set of analog peripherals: 42 channels of 12-bit ADC and 7 channels of 12-bit DAC. This part is aimed at mixed-signal control applications — think motor drives, digital power conversion, and sensor fusion — where you need fast loop closure and a lot of analog inputs without adding external converters. The 100-TFBGA (8x8 mm) package keeps the footprint small, but the BGA pitch means the PCB layout needs careful fanout planning.

Analog channel count and peripheral set

With 42 analog inputs on the 12-bit ADC and 7 DAC outputs, this MCU can handle multi-phase current sensing, voltage monitoring, and waveform generation on a single chip. The connectivity list includes CANbus, I²C, SPI, QSPI, SAI, UART/USART, USB, and IrDA — enough for industrial fieldbus and sensor interfaces.

Lifecycle and sourcing posture

The base product number is STM32G473, so future die revisions or package variants will carry the same base.

Frequently asked questions

What is the maximum clock speed of STM32G473VBH3?

The core runs at 170 MHz. At that speed the flash wait states need to be configured correctly in the clock tree — the datasheet's reference table gives the settings for zero-wait vs one-wait operation.

How does STM32G473VBH3 compare to STM32G474?

The STM32G474 is a close sibling in the same G4 family. The main difference is that the G474 typically offers higher-resolution timers (HRTIM) for advanced power conversion, while the G473 focuses on the analog channel count. Both share the same 170 MHz Cortex-M4 core, 128 KB Flash option, and 100-TFBGA package — pin-compatible across the series, so a board swap is possible if the timer peripheral matches your need.
