Product details

170 MHz real-time control — what the core delivers

It packs 512 KB of Flash and 128 KB of RAM, enough for complex firmware stacks and data buffers in mixed-signal control loops. The single-cycle multiply-and-accumulate and FPU handle fast math for motor field-oriented control or digital power conversion without a separate DSP.

Analog front end — 20 ADC channels, 7 DAC outputs

With 20 x 12-bit ADC inputs and 7 x 12-bit DAC outputs, this part fits applications requiring simultaneous sampling of multiple analog signals — think three-phase motor current sensing plus position feedback, or multi-channel power-supply telemetry. The 12-bit resolution is typical for industrial sensor interfaces where 10- or 12-bit is the baseline. The DAC count is notably high for this package class, reducing the need for external converters in multi-output control systems.

Industrial temperature grade and connectivity

Connectivity includes CANbus, I²C, SPI, QSPI, UART/USART, IrDA, and LINbus — enough interface variety for sensor hubs, gateway nodes, or distributed control networks. The 38 I/O in a 48-LQFP package (7 mm x 7 mm) provide a compact footprint while leaving room for peripheral routing.

Frequently asked questions

What is the maximum operating frequency of STM32G474CET6?

The core runs at 170 MHz, which is the rated speed for this ARM Cortex-M4F device. At that clock, the Flash requires zero wait states for many instruction sequences; above 170 MHz the part is not specified.

What is the flash memory size of STM32G474CET6?

Program memory is 512 KB of Flash, organized as 512K x 8 bits. That is enough for a full real-time control firmware stack including communications stacks and bootloader.

Is STM32G474CET6 compatible with STM32G474R?

The STM32G474CET6 and STM32G474R series share the same core and memory options but differ in package pin count and I/O count. The 'C' in the code indicates 48 pins, while 'R' indicates 64 pins. They are not pin-compatible, but software can be shared with minor peripheral mapping adjustments.
