STM32G4 Series


STM32G4 Series of mixed-signal MCUs with DSP and FPU instructions

The STM32G4 Series combines a 32-bit Arm® Cortex®-M4 core (with FPU and DSP instructions) running at 170 MHz combined with 3 different hardware accelerators: ART Accelerator™, CCM-SRAM routine booster and mathematical accelerators. The STM32G4 Series also offers:

  • Rich advanced analog peripherals (comparator, op-amps, DAC)
  • ADC with hardware oversampling (16-bit resolution)
  • Dual-bank Flash memory with error-correcting code (ECC) (supports in-field firmware upgrades)
  • Securable memory area
  • High-resolution timer version 2
  • USB Type-C interface with Power Delivery including physical layer (PHY)
  • AES hardware encryption

A flexible interconnect matrix allows autonomous communication between peripherals and saves CPU resources and power consumption.

A high degree of compatibility with the STM32F3 Series guarantees outstanding efficiency when designing derivatives of applications at different performance levels.

The STM32G4 Series of mixed-signal microcontrollers consists of:

  • The STM32G4x1 Access line: general-purpose microcontrollers with an entry level set of analog peripherals
  • The STM32G4x3 Performance line: general-purpose microcontrollers with the maximum number of analog peripherals
  • The STM32G4x4 Hi-resolution line with high-resolution timer and complex waveform builder plus event handler (HRTIM) for digital power conversion, such as digital switched-mode power supplies, lighting, welding, solar and wireless charging

Package options are LQPF32/48/64/80/100/128, UFBGA64/100/121, WLCSP48/64/81, UQFN32/48 for devices with 32 up to 512 Kbytes of Flash memory.

Temperature range from -40 to 85° C or from -40 to 125° C.
