STMicroelectronics STM32G4 series of mixed-signal MCUs

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.

STM32G4 Series 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

Key features

• Rich advanced analog peripherals (comparator, op-amps, DAC)
• Dual-bank Flash memory with error-correcting code (ECC) (supports in-field firmware upgrades)
• USB Type-C interface with Power Delivery including physical layer (PHY)

Applications

• Digital power supplies
• Advanced motor controls
• Lighting
• Building-automation products
