Minimum circuit help: STM32F446 with ULPI PHY & Audio Codec

[Davi Roza]

Hi everyone,

​I'm currently developing a MIDI controller/audio device for guitar VST plug-ins.

​The project features a guitar audio input using the CS4272K IC connected to an STM32F446RET6. Additionally, the STM32 will operate in USB High Speed mode using Microchip's USB3300 PHY.

​My main challenge at the moment is finding or designing the standalone minimum circuit (schematic) for these components to move forward with the project. Could anyone provide some guidance or share reference schematics for this setup?

​Thanks in advance!

Hi ​@Davi Roza 

You can refer to STM32446E-EVAL schematics using a WM8994 codec implementation and  USB3300 ULPI PHY for USB HS operations
