STMicroelectronics STM32G4 Microcontrollers

Mixed-signal MCUs feature multiple connectivity options including USB Type-C interface and PHY

STMicroelectronics’ STM32G4 series of microcontrollers provides a combination of high processor throughput, generous provision of analog peripherals, and a choice of connectivity options.

 

The STM32G4 MCUs are based on a 32-bit Arm® Cortex®-M4 core, which includes floating-point unit and digital signal processor instructions, running at a clock speed of 170MHz. The series also offers three kinds of hardware accelerators:

• ART Accelerator™ block for speeding processor-memory interactions

• CCM-SRAM memory routine booster

• Mathematical accelerators

 

The STM32G4 series also offers:

• Advanced analog peripherals, including comparators, operational amplifiers and DACs

• 12-bit ADC

• Dual-bank Flash memory with error-correcting code. The dual-bank configuration supports in-the-field firmware upgrades.

• Securable memory area

• High-resolution timer

• AES hardware encryption

 

Advanced connectivity options include a USB Type-C® interface and physical layer (PHY). The USB Type-C implementation supports the USB Power Delivery specification for controlling power supplied to peripheral devices.

 

The STM32G4 series consists of:

• The STM32G4x1 Access line – general-purpose MCUs with a basic set of analog peripherals

• The STM32G4x3 Performance line – general-purpose MCUs with a high number of analog peripherals

• The STM32G4x4 Hi-resolution line – includes a high-resolution timer and complex waveform builder plus event handler for digital power conversion. This line of MCUs is suitable for applications such as digital switch-mode power supplies, lighting, welding, solar power generation and wireless charging.
