This project is based on the file from stm32 official file. And this version is based on v1.1 and which is released on V1.1 FEBRUARY 28，2019 .
I build it using Altium Designer 2019, but I think you can use the intergration file on any altium designer version (version > 10).
For now, there are three series is include in STM32G4 series and they are STMG4x1, STM32G4x3 and STM32G4x4 depending on if they include FSMC or High-Resolution Timer.
The STM32G4x1 are mixed-signal microcontrollers with an Arm® Cortex®-M4 core (with FPU and DSP instructions) running at 170 MHz. These are entry-level devices in the STM32G4 series .They cover 10 packages: LQFP32, UFQFPN32, LQFP48, UFQFPN48, WLSP49, LQFP64, UFBGA64, LQFP80, LQFP100 and BGA100.
The STM32G4x3 are mixed-signal microcontrollers with an Arm® Cortex®-M4 core (with FPU and DSP instructions) running at 170 MHz. These are performance devices in the STM32G4 series, which embed a maximum number of analog peripherals. They include LQFP48, UFQFPN48,LQFP64, LQFP80, WLCSP81, LQFP100, BGA100 and LQFP128.
The STM32G4x4 Hi-resolution line specifically addresses digital power conversion applications, such as D-SMPS, lighting, welding, inverters for solar systems and wireless chargers. They cover LQFP48, UFQFPN48, LQFP64, UFBGA64, LQFP80, WLCSP81, LQFP100, BGA100 and LQFP128.
