Description
STM32G474CET3TR is an STM32G4 32-bit microcontroller from STMicroelectronics. It uses an ARM Cortex-M4F core with DSP and floating-point support, typically running up to about 170 MHz. Memory and I/O vary by package, commonly offering up to around 1 MB of Flash and tens to hundreds of KB of RAM. Peripherals include multi-channel 12-bit ADCs and a DAC with analog front-ends, op-amps, several timers (including advanced-control timers), and broad connectivity (USB, CAN, I2C, SPI, USART). It suits motor control, power electronics, audio, and mixed-signal sensor applications, with low-power modes for energy efficiency. Security/crypto peripherals are available on many STM32G4 parts. Development is supported by STM32CubeIDE, HAL/LL libraries, and ST’s ecosystem. The CET3TR suffix specifies a particular package/configuration and tape‑and‑reel shipping; check the datasheet for the exact pinout, RAM/Flash, and IO for this variant.
