Product details

The STM32G474CBT3: The 128 KB of Flash and 128 KB of SRAM are balanced for mid-complexity firmware. It comes in a 48-LQFP package with 38 I/O.

Industrial temperature grade — deployment context

The internal oscillator allows boot without an external crystal.

Analog integration — ADC and DAC count

Twenty 12-bit ADC channels and seven 12-bit DAC channels are on-chip. That is a lot of analog I/O for a 48-pin MCU — enough to sample three-phase currents plus a DC-link voltage while generating multiple analog references or setpoints. The peripherals include CANbus, I²C, SPI, QSPI, UART/USART, and IrDA, so it talks to most sensor and actuator buses without external transceivers beyond the physical layer.

Lifecycle and supply posture

This is a current-production part suitable for new designs.

Frequently asked questions

What is the difference between STM32G474CBT3 and STM32G474CBT6?

The STM32G474CBT3 and STM32G474CBT6 share the same core, Flash size, RAM, and peripheral set. If your application requires the extended 125°C junction temperature, the CBT3 is the correct choice.
