STMicroelectronics STM32G4 series mixed-signal MCUs

The STM32G4 series combines a 32-bit Arm® Cortex®-M4 core with FPU and DSP instructions, running at 170 MHz, 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 (MCUs) with an entry-level set of analog peripherals
• The STM32G4x3 Performance Line: general-purpose MCUs with the maximum number of analog peripherals
• The STM32G4x4 Hi-Res Line: high-resolution timer, complex waveform builder, and event handler (HRTIM) for digital power conversion

Key features

• Rich Advanced Analog Peripherals (Comparator, Op-Amps, DAC)
• Dual-Bank Flash Memory with Error-Correcting Code (Supports In-Field Firmware Upgrades)
• USB Type-C Interface with Power Delivery, Including Physical Layer (PHY)
• A Comprehensive Set of Power-Saving Modes Allows Design of Low-Power Applications

Additional features

• ADC with Hardware Oversampling (16-bit Resolution)
• Securable Memory Area
• High-Resolution Timer Version 2
• AES Hardware Encryption

Applications

• Digital Power Supplies
• Advanced Motor Controls
• Lighting
• Building Automation Products
