Product details

100 MHz Cortex-M4 with 1.5 MB Flash — industrial control and connectivity hub

The STM32F423CHU6: Connectivity includes CANbus, I²C, SPI, UART/USART, USB OTG, SAI, and MMC/SD. Ten 12-bit ADC channels and two 12-bit DAC channels cover analog sensing and control outputs.

Industrial temperature grade and compact 48-UFQFN package

The 48-UFQFN exposed-pad package measures 7x7 mm. With 36 I/O available, the pin count is modest — suited for designs that need a rich peripheral set (CAN, USB OTG, multiple UARTs and SPI) in a small footprint.

Frequently asked questions

What is the difference between STM32F423 and STM32F413?

The STM32F423 is a lower-pin-count, smaller-package variant (48-UFQFN vs typically larger packages on the STM32F413). Both share the same 100 MHz Cortex-M4 core and 1.5 MB Flash, but the STM32F423CHU6 offers 36 I/O and a reduced peripheral set compared to the higher-pin-count STM32F413 parts. The exact peripheral differences are detailed in the STM32F4 reference manual.

What is the closest pin-compatible alternative to STM32F423CHU6?

Within the STM32F4 series, the STM32F423 family shares the same 48-UFQFN footprint and pinout across density options. The STM32F413 parts use different packages and are not pin-compatible. For a direct drop-in, check the STM32F423xH variants with the same 48-UFQFN package — they differ only in Flash and SRAM sizes.
