Product details

The STM32F423RHT6TR: Connectivity includes CANbus, USB OTG, QSPI, SAI, and multiple UART/SPI/I²C interfaces — enough to tie into a CANopen fieldbus, drive a QSPI NOR Flash for code shadowing, and pipe audio over SAI simultaneously. The 50 GPIOs in a 64-LQFP package leave headroom for a local keypad and status LEDs alongside the main bus. Operating from 1.7 V to 3.6 V and rated -40°C to 85°C, this part fits industrial control panels, outdoor telecom gear, and automotive cabin-adjacent modules. The internal oscillator and brown-out detect reduce external BOM count — no external crystal or reset supervisor needed for many designs.

EOL status — plan the last buy now

The STM32F423RHT6TR carries an EOL hot lifecycle marker. That means the manufacturer has announced end-of-life; the last-time-buy window is open but finite.
