Product details

STM32F423RHT6 — 100 MHz Cortex-M4 with 1.5 MB Flash

The STM32F423RHT6 is a 32-bit ARM Cortex-M4 MCU from ST's STM32F4 series, clocked at 100 MHz with 1.5 MB of Flash program memory and 320 KB of RAM. This is the high-density member of the STM32F423 line, aimed at applications that need substantial on-chip code storage alongside real-time connectivity — think motor drives with CANopen fieldbus, industrial gateways with USB host/device dual role, or multi-sensor data loggers.

The 100 MHz Cortex-M4 core with FPU handles single-cycle MAC operations and real-time FFT or filter execution. The STM32F423RHT6's 1.5 MB Flash is the deciding factor when the firmware image exceeds half a megabyte.

Peripheral set: USB OTG and CANbus on one chip

This MCU carries both USB OTG and a CANbus controller, so a single part can serve as a USB-to-CAN gateway or a CANopen node with a USB service port.
