Hello ST Community,

I am looking for an STM32F4 series microcontroller that meets the following requirements:

:small_blue_diamond: Microcontroller Requirements:
:white_heavy_check_mark: More than 2 UART ports
:white_heavy_check_mark: Quad SPI support
:white_heavy_check_mark: Operating frequency: 100-120 MHz
:white_heavy_check_mark: Preferred package: TQFP/LQFP, but open to other suggestions

Since this MCU will be used in an embedded system, power efficiency and peripheral availability are key considerations.

STM32F4 series

Distributors often have good parametric search tools ...

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.

Have you ever filtered your selection on the websites of the STM32F4?

Hello,

For power efficiency as you mentionned, you might want to look at a newer STM32 range as the F4 family is a bit old.

For example STM32U5 or STM32L4+.
