STM32 with at least 4x SPI and 2x USB

DZ888 · ‎2026-04-08

Dear STMicroelectronics Team,

I am looking for an STM32 microcontroller for a new project. My main requirements are:

At least 4 SPI interfaces
At least 2 USB interfaces

Could you please suggest suitable STM32 part numbers that meet or come close to these requirements?

Thank you for your support.

Best regards,

DZ

You can also search using STM32CubeMX

Distributors also often have parametric search facilities ...

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

Hello @DZ888 and welcome to the ST community,

You can use STM32 Cube finder tool or CubeMx tool then you fine tune the selection with the datasheet.

For example: STM32F429 has 5 SPIs and two USB interfaces: USB_OTG_FS (Full speed) and USB_OTG_HS (High speed):

STM32F746 has 6xSPIs and two USB interfaces: USB_OTG_FS (Full speed) and USB_OTG_HS (High speed):

You need take care about the chip price and the performance you need in your application.
